Debian on Dell Kace M300

sudos, welcome to the party! I mentioned it in another thread, but I've been meaning to mention here as well where maybe it will get more attention. I removed the CPU from one of my M300s and it's like nothing I've ever seen. I could trace the GPIOs if I could just a pinout for the 88F6282 in the FCBGA package, so if anyone has a source for Marvell data sheets let me know.

There is no need to do that anymore (postpone that approach for now). I did a surgery of stock uboot. And what we are using in the new u-boot is stock header. It seems to be working fine for me.

So the issue is if others can test this new u-boot to their satisfaction.

I would be most interested in is running the box without any USB drive plugged in. Just use the stock SSD or your new SDD in the SATA slot. When this configuration is running OK, then we know we've solved the power problem.

Here is the latest u-boot.

is this also not flashable yet?

Not yet. I will do that while writing the instruction.

But it does not hurt if you can try kwboot it.

After booting many times with the new u-boot using my two stock SSDs one boots reliably while the other does the same old sometimes it boots, sometimes it kernel panics, sometimes it segmentation faults, and sometimes it spews error messages ad nauseam. I think it still boots reliably if I have something in the USB port.

I'm ready to flash this anyway since it boots my USB flash drive reliably while the stock u-boot does not.

I tried your latest kwb file on my Kace. It seems to have broken in the same place as the previous one:

[root@CQ50 Downloads]# kwboot -p -t -B 115200 -b uboot.2021.10-tld-1.m300.mtd0.kwb /dev/ttyUSB0

Success at latest kwboot!

I bungled an attempt to upgrade the 5.2.9 kernel so had to start over with a fresh mSATA formatted to ext3. Not quite the same kernel as yours but close.

does it still have the same no-boot behavior unless something is plugged into USB with the latest kernel/rootfs combo?

Not for me. The only drive I have on this box is the internal SSD. No other USB gadget.

One of my two SSDs still has that behavior. They're running two different debian versions (buster vs bullseye), so I don't know if that has anything to do with it. I'll have to check if they're also using different kernel versions (I don't think so). I'm going to clone the working SSD to the non-working and see what happens when I get a chance.

For kwboot, it worked with or without a USB device plugged in. Switching back to the original uboot it would only boot the mSATA with something plugged into USB. Same as before so it doesn't seem to be the fault of the kernel or Debian version.

That's a very good test dougdeep! I was hoping to hear that from somebody. Myself alone is only one data point, after all :)

Basically, the new u-boot married the stock u-boot header with modern u-boot code. That was my plan B from the start. In retrospect, that should have been plan A.

But the ultimate test would be to flash it to SPI flash, and run with mSATA only drive for a while to see there is any abnormal behavior.

At the moment, the only possible installation on flash is to have serial console to unprotect the flash before writing, so I'm not satisified yet. But, perhaps we'll live with that restriction for now, and refine it with a patch in the next kernel release.

Cloning the reliable SSD to the unreliable one definitely made things better. I did get this a couple of times:

After seeing the above a couple of times I haven't seen it again after another half dozen boots.

In case it matters, before I cloned the "better" SSD it had Kernel version 5.2.9 and Debian version 10.0. It now has Kernel version 5.16.5 and Debian version 11.2 and is more reliable as far as booting goes.

I may have to admit it's just a flaky SSD because I can't say for certain that it always boots with something in the USB port. I've noticed before that it usually boots the first time after it's been sitting on my desk for a while and starts to fail once it warms up. However, even "warmed up" it will boot with something in the USB port with the stock u-boot or the modified ones.

I'm still ready to flash this thing, so if you need a guinea pig I'm here. :-)

I'm tracking down a problem with the SPI flash. I have flashed it to SPI and it runs beautifully, but the envs always end up having CRC error upon boot. Not sure why yet.

Let me post it and you guys can flash with that caveat.

-bodhi

Here is the new u-boot. This image can be flashed to SPI mtd0.

At the moment, I still have some problem flashing the default envs image in Debian, so that will come later.

1. Unprotect the SPI flash

Boot with serial console, interrupt u-boot count down and unprotect the SPI flash

protect off all

Expected output

Un-Protect Flash Bank # 1
................................................................................................................................ done

And then go ahead boot into Debian

boot

2. Flash new u-boot

Log into Debian, download the attached u-boot image. And flash it.

flash_unlock /dev/mtd0
flashcp -v uboot.2021.10-tld-1.m300.mtd0.kwb   /dev/mtd0

Expected output

Erasing blocks: 96/96 (100%)
Writing data: 384k/384k (100%)
Verifying data: 384k/384k (100%)

3. Prepare the rootfs to boot with new u-boot.

As we have been booting with stock u-boot, the DTB is appended to uImage. So it should be restored to the original uImage before we will boot with separate DTB.

cd /boot
cp -a uImage uImage.m300.dtb
cp -a uImage.orig uImage

Or just recreate uImage

mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.16.5-kirkwood-tld-1 -d vmlinuz-5.16.5-kirkwood-tld-1 uImage

4. Prepare the uEnv.xt.

Replace the ethaddr, ipaddr, and serverip values to the appropriate ones for your box. The other envs are optional, nice to have (it will make booting faster).

cat /boot/uEnv.xt

ethaddr=18:03:73:xx:xx:xx
ipaddr=192.168.0.249
serverip=192.168.0.220
custom_params=raid=noautodetect
bootdev=sata
devices=sata usb

And then sync and reboot

sync
sync
sync
shutdown -r now

Observer serial console output, the banner should show

U-Boot 2021.10-tld-1 (Mar 15 2022 - 13:07:52 -0700)

Just let it boot automatically into Debian. And if there is problem, please post serial boot log. Or if you'd like, post it anyway so I can doublecheck.

Well it boots from SATA, but I can't get it to boot from USB. I need to take a break since I've watched this thing boot or not boot dozens of times today.

Since the DTB is removed from uImage should there be a directive in uEnv.txt? I tried adding one, but it still kernel panics when I try to boot from USB. Without any dtb entry I got something like a machine ID error and something else when trying to boot from USB, but my brain is fried and I can't remember anything right now. I may have messed up something else. I'll try again and post a log later.

Whether booting from USB or SATA, you can recreate the uImage to make sure that it has no DTB appended.

mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.16.5-kirkwood-tld-1 -d vmlinuz-5.16.5-kirkwood-tld-1 uImage

The DTB file is defaulted to the correct location, so there is no set up need.

Power up, interrupt u-boot countdown and

printenv
boot

Success! changed root login, flashed the uboot image from stock Debian, set up a spare SSD with 5.13.6 and used a mixture of the "permanent" uboot envs from the M300-specific tutorial post and such to get it to boot off SATA. it works!!

up next will be upgrading it to the latest kernel and seeing how that fares.

So far I can confirm that the kirkwood core in the Armada SoC is faster than any of the other embedded ARM devices I have, and especially the Pi Zero I used for serial console. simple calculation of Pi to 5 digits confirms this...
Using:

time echo "scale=5000; a(1)*4" | bc -l

the M300 did it in one minute 5 seconds, the Pi Zero took 2 minutes 34 seconds, the Pogoplug E02 took 1 minute 51 seconds, and the Pogo v4 did it in 2 minutes 45 seconds.

As others have said, that makes this a very, VERY nice little embedded ARM device, despite being softfloat.

can also confirm that as I expected, putting a thermal gap pad on the SSD's main Silicon Motion SoC helps drastically with data transfer speeds, going from 65MB/s without a gap pad and going up to 92MB/s with one fitted to sink it to the motherboard. In the near future I'm going to acquire a used SanDisk X110 128GB SSD which once de-cased, will be exactly the same dimensions as the SSD this came with and thus should be able to mount cleanly. the addition of DRAM cache with that should help even more drastically to up the disk speed up to the limits of what the SoC can dish out... and be much, much faster than such a disk with the Pogo v4 by comparison. (the X110 should also not need heatsinking to get to this level of performance.)

will continue to follow along as more progress is made, but right now, I have a booting M300 :D

BTW, this SoC (6282) is branded as Armada 300. But it is really a clone of the Kirkwood 6281 (armv5). Starting the Armada 370 SoC, the architecture is armv7.

bodhi, sorry for the false alarm about USB booting. I thought my uImage.orig was of dubious origins and was in fact from a different kernel version. I have to stop experimenting after midnight.

I recreated uImage and can now boot from SSD or USB. Very nicely done!

One thing, I don't see any CRC errors when I boot and I was able to change and save bootdelay. Maybe I'm misunderstanding what you mean about env CRC errors. I did see them when I was using kwboot, but not now.

Did you save it in serial console? that works for me, too. What I meant was doing fw_setenv in Debian.

Could you guys try this in Debian. Only do this if you have serial console connected so you can see in serial log that the CRC has error. And remember to keep using the Env.txt, so that if CRC error occurs, then the boot will be just like you expected it to.

fw_setenv bootdev sata
fw_setenv devices 'sata usb'

If you have no problem then it is probably related to my 2nd M300 box. I have not yet tried to save envs on my 1st M300.

-bodhi

Now that you mention it, I set bootdelay from the M300 prompt. Sure enough, if I try to use fw_setenv I get a CRC error. Definitely not a huge drawback in my opinion. I'd much rather have reliable booting than the ability to set environment variables from within Debian. :-)

Also, since we have uEnv.txt capability, almost all of the envs can be set "in Debian" (except bootcmd and bootcmd_uenv).

But this should be fixed eventually. I think there must be a misatch between the new u-boot SPI driver settings and the Linux kernel driver settings for this mx25l4005a SPI somewhere.

Bodhi,

Have you tried adjusting the spi-max-frequency in the dts to see if that might have an affect on writing to the flash?

That's a good point (something worth to look at).

However, at the moment, they are the same. Because this new u-boot uses the same DTS from the kernel.

I wonder if there's something else going on with the flash. I was trying to get netconsole working and playing with env vars from u-boot and after adding a few I got a CRC error on the next boot. It's like I can change one and save it with no problem, but adding a few will eventually cause a CRC error.

JT,

Netconsole has not been complete. I was going to look at that next. There was something changed in mainline in this area.

> adding a few will eventually cause a

Right!

The odd thing is that after you reverse the change in Debian, it was back to normal. So it seems the checksum is the problem.

Perhaps I've missed some thing new related to this specific SPI flash driver (mx25l4005a).

I think I will rebase to 2022.04 version for this box before doing more troubleshooting.
