Neal,

When you list the GPIO in Linux, they are exactly what the DTS defines.

No, I did not find Poweroff. However, shutdown is working fine in Debian, so looks like there is no GPIO for Poweroff.

There are other GPIOs that this u-boot defines, but they don't seem to have any effect when I poke them.

Without GPL source code, it will take too much time to complete a new u-boot for this box.

That's a shame, but you've done quite a lot! Thanks for all the work you've put into making this into a quite capable little server!

The M300 went into production today with the 120GB SSD and the cover installed. It's had a week or two of burn-in and several successful boots. No haveged, I just wait. The SSD is secured with zip ties through a couple of fittings installed in the tapped holes in the enclosure on each side of the SSD. Working great. Thanks Bodhi!

FYI, there are mainline works going on for kernel 5.4.x which will solve the entropy delay issue.

Just wanted to let those interested know that the M300 does indeed support port multiplication as I had earlier hoped. I bought a 22 pin male to male adapter and a SATA to ESATA cable and hooked these up (via ESATA cable) to a Sans Digital 4 bay ESATA external disk enclosure.

The 22 pin male to male adapter is here: https://www.amazon.com/gp/product/B00S6HTVGI/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
The SATA to external ESATA port cable is here: https://www.amazon.com/gp/product/B000GX4C7I/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1


I have attached pics of the setup linked below.

/dev/sdb:

 Timing buffered disk reads: 218 MB in  3.02 seconds =  72.24 MB/sec
root@debian:~# hdparm -Tt /dev/sdc

/dev/sdc:
 Timing cached reads:   816 MB in  2.00 seconds = 407.27 MB/sec
 Timing buffered disk reads: 194 MB in  3.01 seconds =  64.38 MB/sec

Have to admit not the performance I was hoping for therefor I am debating whether it's worth it to go through the hassle of putting a hole in the beautiful enclosure for the ESATA port.

Your thoughts / impressions bodhi?

LeggoMyEggo,

Cool! Port multiplier works so that would make this box substantially more powerful than the NSA325 :)

This might need adjustment

root@debian:~# dd if=/dev/zero of=/media/output bs=8k count=100k; rm -f /media/output

I hope it was the case that you've overlooked this: If your rootfs is USB then /media/output is on /dev/sda1. So the dd test should be tried on sdb1 or sdc1, after you've mounted them.

I had mounted /dev/sdb1 to /media before performing the test.

Then I would suggest plugging in a SATA cable directly for the single HHD test (to remove the possible slow down impact by external HDD enclosure controller).

For comparisons sake, I mounted the stock SSD module to media and tested.

root@debian:~# mount /dev/sda2 /media
root@debian:~# cd /media
root@debian:/media# dd if=/dev/zero of=/media/output bs=8k count=100k; rm -f /media/output
102400+0 records in
102400+0 records out
838860800 bytes (839 MB, 800 MiB) copied, 31.1632 s, 26.9 MB/s 

root@debian:/media# hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   766 MB in  2.00 seconds = 383.06 MB/sec
 Timing buffered disk reads: 210 MB in  3.00 seconds =  69.99 MB/sec

Have to dig out a single external ESATA enclosure I have somewhere to test your hypothesis about the controller of the Sans Digital ESATA unit. It is an older model I picked up used and it is SATA II but that should not mean much as the controller in the M300 is SATA 2 as well.

Leggo,

> Have to dig out a single external ESATA enclosure

I think the enclosure of any type would effect the speed. I don't recall right now if this M300 SATA is a 22 pin connector type, I'm thinking about a direct cable connection.

It is. See first picture in my upper post for the way I adapted 22 pin to 7 pin SATA.

Just curious, what performance read / write would you have expected given the M300's specs?

The NSA325 (1.6 GHz CPU) benchmarks tested with older kernel.

I did not save dd test. But usually it is about 70MB/s write speed cp a large file (> 1GB) on NSA325.

Re: Debian on Dell Kace M300

I'm trying to get my second M300 going. I have installed the Debian filesystem (5.9.2 with M300 DTB) on a 4GB partition of the 16GB SSD card that comes in the M300. The remaining space on the card is formatted EXT 3 to be used for data. I had this card running on my frist M300 back in September with no significant problems that I can recall. After installing it in the new M300, making the environment settings, testing with a USB drive (OK) and then booting from the SSD card, I've run into several boot failures with kernel panic. The environments are set to boot USB first, if that is not found, then to boot SATA. Here is the serial log of the latest:

Mike,

It's software. Try mounting this SD card on another Linux box and running chkdisk. If it does not help, create a new rootfs and boot with it.

Hi all, I saw mikeh49's post over on the slimdevices forum which had a link back here and just wanted to say thanks for the info and work you've done on the m300. I bought 1 off ebay for $13.95 shipped (new in the box) and once I got it I felt like it was such a good deal I bought 3 more!

I've been spending a lot of time with Alpine Linux and have been working on getting all the components of squeezebox ecosystem working with it (Logitech Media Server, squeezelite, jivelite), mostly on RPi's, but now have a cross-compiled base load of Alpine running on the m300, using the info from this thread and the kernel config and dts file that bodhi made available.

This could change, but right now I've got a StarTech dual m.2 to sata adapter configured as a jbod, 2x 500GB HP m.2 ssd's with 2 md raid partitions being autodetected by the kernel using the 0.90 metadata version. I've got a 100M partition mounted on /boot and then the second partition is the rest of the space ~465GB.

For whatever reason I thought it would be nice to not change the uboot environment variables from the stock, so right now I've got the uImage file of the 5.4.18 kernel with appended .dtb that I changed the dts file bootparams to include root=/dev/md1 and I'm not using an initramfs but created an empty uInitrd file to keep uboot happy.

It's a bit early yet but things seem to be mostly working.

Nice use of the internal SATA port!

That's a good alternative if you stay with this system configuration and not booting other. You can also make another DTS to boot USB rootfs (root=/dev/sdxx) to be a rescue system. It is not flexible as using root device label in u-boot env, but since you already know how the DTS should be coded, so not bad at all!

Funny you mention it, I've spent a number of hours (and spent some brain cells) trying to get bluetooth audio working with squeezelite and pulseaudio on the M300. Have the logitechmediaserver working as well after recompiling CPAN for Debian 10. It works for the most part but I am having issues getting things to auto load after boot.

The problem for us not using RasPi's is that everything is written for Raspi! I have Raspi 3 and 4 but from a hacking point of view they are not as much a challenge. Throw in it being headless without display and it increases the challenge. Quite the bargain this M300 is, if only it had USB3.0 or mPCIe but you won't find another Kirkwood device running at 2GHZ and with 2 Gigs of Ram. They are so cheap, I have three of them. Plus you get network cables and if the unit shits the bed, you can recycle the SATA drive for other projects. This is now my favorite 'play plug' with the Cisco ON100 (Onplus) a close second.

Thanks. Next job is to get the bottom plate drilled out so I can mount the drive brackets and get it closed back up. Hopefully it doesn't get too hot in there!

I did boot from USB to set up the raid partitions. I originally tried to do it on my laptop by connecting the dual sata adapter via a USB adapter but it was only able to see one of the two drives - I guess it doesn't provide the port multiplier support that the m300 controller does. I tried to setup the md partitions with just one drive using the "missing" keyword for the second drive, thinking I could add it later on the m300 but I couldn't get it working. Which is to say, yes, a rescue usb is probably a great idea!!

You are using a USB DAC? Any recommendations? I thought this Topping D50S in silver would go nicely with the m300 but I'm too much of a tight wad to spend $250 on a DAC.
http://amzn.com/B07VJMJVC6

I don't have any squeezebox stuff working with Alpine on the M300 yet - just got the base OS to the point today that I think it looks good to press on. LMS will be the hardest to get going but is really the main thing I want to use this box for. Squeezelite with a DAC is a possibility but I'm not running any audio out of my current LMS server since I have numerous other players in service already.

Completely agree on all points! I've spent way more time on the m300 than on the RPi4 I got for Christmas. Not sure what that says about me?? That and the fact I'm planning on replacing my 10 year old Atom based LMS / file server with a 9 year old M300!?

I've thought about USB DAC for the M300, even noticed the one you like (nice match to the finish of the M300), this one is about the most I would spend: Cheap USB DAC Hope it performs better than my cheap Sarbent USB audio adapter. There are dozens upon dozens of these things, some that cost north of $2,000 and I don't necessarily trust the reviews.

Only problem with getting LMS to work on the M300 is that the pre-compiled CPAN version is meant for armhf (aka RasPi). For Debian 10, after you dpkg the latest nightly deb (which will fail to start because of the missing proper CPAN), you need to clone the slimserver git at https://github.com/Logitech/slimserver-vendor.git, switch to the CPAN subdirectory and run the buildme.sh script. This will create 5.28 version of CPAN that you will need to manually copy per the instructions on this page: https://github.com/Logitech/slimserver-vendor/tree/public/7.9/CPAN. Note the required packages you will need before compiling. Restart logitechmediaserver after the new CPAN directory has been copied.

Re: Debian on Dell Kace M300

A user on the LMS forum has compiled Perl 5.28 for LMS and posted it here:
https://github.com/mw9/slimserver/commit/46c22a3c7e69187a2ead9392c53f1c90790a03fa

I could not get the buildme script to work, this kind soul stepped up on the forum and saved me. LMS has been running great on the M300 for about 5 months with a internal 120GB drive plugged into the SATA port.

I have been happy with the Muse DAC, typically available on ebay, but only see one there now. Maybe the virus.
https://www.ebay.com/itm/MUSE-HIFI-USB-to-S-PDIF-Coaxial-Optical-Converter-Analog-out-USB-DAC-PCM2704/392620943106?hash=item5b6a082702:g:7JsAAOSwbyVdIujg

Also, hifimediy has a well regarded DAC:
https://www.amazon.com/HiFiMeDIY-Digital-Analog-Converter-Optical/dp/B00AOH5JTQ/ref=sr_1_2?keywords=hifimediy&qid=1581626227&s=hi&sr=8-2

Both of these are in the non-audiophile price range, but are not junk either. I have one of the junk ones and one that looks like junk but sounds pretty good.

Re: Debian on Dell Kace M300
February 18, 2020 09:27AM
Thanks for the info mikeh49. I bought an Apple USB-C dongle/DAC and a two pack of USB-C to USB-A adapters from Amazon based on this review and some other positive comments about the Apple dongle:

https://www.audiosciencereview.com/forum/index.php?threads/review-apple-vs-google-usb-c-headphone-adapters.5541/

It's the first Apple product I've ever purchased and I did it reluctantly but I figure it was just a $8 dongle so it didn't really count, of course my daughter said that full Apple conversion is now required (not likely!). I can confirm it works on my Fedora laptop and it looks like it is recognized correctly on the M300 but I don't have alsa or any of the other necessary packages built for Alpine yet so I haven't been able to test it.

I ran into an issue with Alpine's package manager that you can read about here:
https://lists.alpinelinux.org/~alpine/apk-tools/%3CCAGP1gyMH+GoXnGd3YQjg4piFYpMpNiHkC7PDO7BoHTSbYsP1Ug%40mail.gmail.com%3E

Came down to an issue with memory alignment that I never would have figured out on my own. I did find a couple references to it here on this site (after I knew what to search for) - this must be something that the Debian port accounts for in their configuration?

Would one of you post the results of cat /proc/cpu/alignment so I can configure Alpine the same way?

Thanks!

Re: Debian on Dell Kace M300
February 18, 2020 01:43PM
Thanks Mike, this memory alignment thing on the M300 may be something that could also affect you guys running Debian.

See:
https://wiki.debian.org/ArmEabiFixes#word_accesses_must_be_aligned_to_a_multiple_of_their_size
and
https://www.kernel.org/doc/html/latest/arm/mem_alignment.html

It looks like by your output above that you are set to "0" which I believe is what my Alpine install defaulted to and was causing the problem I talked about in the mailing list thread I linked to.

"0" supposedly means "A user process performing an unaligned memory access will cause the kernel to print a message indicating process name, pid, pc, instruction, address, and the fault code." but if it was printing any messages I never saw them anywhere. The crappy part about it was that the apk command I was using (alpine's package manager) worked for some things, sort of worked for others, and didn't work at all for still others, but the command never actually caused a crash or seg fault or anything else that would be an _obvious_ problem. I'd rather have that then something that "sort of" works and leaves you wondering what else can't be trusted.

//edit, see also https://stackoverflow.com/questions/16548059/how-to-trap-unaligned-memory-access

I'd be curious to see if you did a:
echo 2 > /proc/cpu/alignment

let the system run for a while and cat the file periodically if you'd see fault numbers going up (and being corrected by the kernel) which I think would mean that at the current setting of 0, the faults were still there, just not being caught and what's worse, not being corrected.

I could be completely misunderstanding the situation and settings, I just know I ran into an issue and it looks like you are running with the same setting I was.

//edit 2, now that I'm home I pulled the /cat/proc/alignment info off the two m300 I have running, keep in mind that the one that says "2 (fixup)" I just changed yesterday by doing the "echo 2 > /proc/cpu/alignment" as a troubleshooting step, so It's been running at 0 like the other one for the majority of it's uptime.

Don't know what your uptime was but it looks like you've had 0 errors which seems like a good thing. I think it either means your system config is accounting for it somehow or all the software you're running is coded to only do aligned memory access (or whatever the correct way of stating that is).

sodface,

This box architecture is Armv5te, i.e Kirkwood. Same as other Kirkwood boxes that we have been supporting since kernel 3.16.x. So I dont think alignment is a problem at all.

Hi bodhi, you guys have way more knowledge on this than I do so I don't doubt you are correct, at least for debian, which is what this forum is about so I probably shouldn't be posting about Alpine here anyway. I'm definitely seeing memory alignment problems with this one application on Alpine though, as you can see from the number of errors in my output above. Mike's output from his one box indicates 3 errors so it doesn't seem to be a complete non-issue on debian but certainly nothing like I'm seeing. I think this is largely dependent on the application and how it's coded.

On the contrary, when you're out of idea to fix something, please post here. We welcome any Linux distro users. You should see a very long thread about booting FreeBSD here :) We will learn something from it.

I did not recall Mike has "bus error" ? usually iirc that it is hardware problem, or running a binary that was compiled for a wrong architecture. If other binaries are running fine on Alpine on this box, and then just one binary that has bus error, then it itself is suspected.

FWIW, here's the alignment info from a Pogo E02 running latest Debian and samba:
root@BlackPogo:~# uptime
 03:28:46 up 7 days, 18:05,  1 user,  load average: 0.00, 0.00, 0.00
root@BlackPogo:~# cat /proc/cpu/alignment

The M300 with the errors is running Logitech Media Server with Perl modules compiled by a LMS forum member for armel. Don't know if that means anything It'd s pretty big app I think. .
