Dockstar mods: SATA, SD, 256MB RAM, Compiling/Modding U-boot; kernel DTB...
November 09, 2021 10:07AM
Hi,

First I must thank the community, specially Bodhi for supporting the project during all this time!

I got a Dockstar about 9 years ago, served me well, however I always wanted to try lifting the cpu and directly interfacing the native sata.
I wanted a small NAS but the USB became too slow for modern networks, so I stopped using it.
Since it's been unused for 2 or 3 years, I decided to try, I had nothing to lose.
I lifted the CPU, cleaned everything and soldered 4 very thin wires to the sata bga pads.
Suprisingly the surgery was successful, it booted fine after reballing the CPU. Everything seems ok.

Some pictures:

But, as I suspected, the sata interface is disabled.
I guess I have to make a custom DTB, or maybe there's another Kirkwood/Pogoplug device that shares the same hw but adding sata support?

Edit: Add useful post links:

- Dockstar picture gallery (HW mods etc)
- U-boot compiling
- U-boot mods
- Nand-less, loading uboot from sata
- JTAG recovery with $5 stm32 blue pill
- Compiling DTS

Cheers,
David

Hi David,

Nice mod!

You don't need compile anything. Use the GoFlex Net DTB and it will run fine.

/boot/dts/kirkwood-goflexnet.dtb

If you have installed the new u-boot then you need to change the env to boot with it. If you run stock u-boot with DTB appended to uImage, then recreate the uImage with the GoFlex Net DTB.

Later, if you want it to identfy as a real Dockstar, we'll just modify the Dockstar DTS and add 1 SATA port to it, and recompile the DTS.

- arcNumber. Tried other numbers, did nothing, so I guess I definitley need a new DTB to define the hardware changes.
- DTB. Where and how?

Arch number is no longer important with the new kernel. DTB is all the kernel will use to know the hardware (with old and non-FDT kernels, the ArchNumber is important).

I already updated u-boot back in the day (2017.07).
I don't really care about what it says it is, as long asthe hardware works.

Edit: I also had to flash goflexnet uboot to get "ide" command.
For now it's not working, might be wired incorrectly, or it could be a signal quality issue.
More testing coming!

At uboot, I get this:
GoFlexNet> ide reset
Reset IDE: ide_preinit failed

Do you know if that error is caused by some internal sata interface issue, or if it's due communication issues to the sata hdd?

Thanks a lot!

"ide_preinit failed" means either there is no SATA plugged in, or the wires are not connected correctly, or the SATA GPIO is misconfigured (i.e. no power). So it could be either.

But given how closely related the GoFlex Net and the Dockstar are, I would try to boot into Debian first, and check the SATA in dmesg. This would be the quickest way to see if it works. When it works in Linux, then you know your wiring is good.

u-boot is a bit more complicated to test, it has more moving parts.

I think it should work right away. There're only 2 sata interfaces, can't be mapped to any random pin.

Using goflex net uboot+dtb, everything works normally... except sata.

I've tried everything. I know the sata pins are ok, I can see the Sata pins in diode mode (internal ESD diodes) and the 120Ohms sata termination resistors for each Rx/Tx pair (Internal, inside the soc).
So everything seems correct. But no way.

The sata shield is connected to solid ground in the board, everything is very short to avoid signal issues. (From Kirkwood bga pins to sata cable, 20-30mm).
I've tried every wire combination, too, just in case. Nothing. Damn, I thought it was going to be a simple hardware cross-flashing mod.

Dmesg:

So yeah, the sata interface seems to be there, but sees nothing at the other side.

If you are confident that the hardware is correct. Then we'll move on to the DTS and GPIO.

At this point, the usual suspect is the SATA power. Kirkwood SoCs has MPP (pin multiplexer) so each vendor might use a different pin (i.e. GPIO) to control the SATA active and power.

The GoFlex Net and the Dockstar MPP definitions are different. However, only USB Power is needed to be explicit (GPIO 29 for both boards). No explicit HDD power GPIO is needed. That means the HDD power is default as in the datasheet.

Let's try another approach. Even though you had flashed the GoGex Net u-boot, it mightbe better to run the Dockstar DTB.

I'll compile the Dockstar DTB with SATA enable and see if the behavior is any different. Later, you can also do this using DTC compiler. But let me upload the new Dockstar DTS and DTB first.

No wonder it failed... I missed the Sata Vdd pin! (Power)
I didn't knew sata used its own power... It's unconnected in the dockstar.
So cpu needs to be lifted again.

Aaaand..working!

Lifted the cpu again, bridged VDO (3.3V) to Sata_0_VDD and Sata_1_VDD.
I also exposed Sata0 pins this time.
And it worked!

I know the picture looks dirty... Was before the cleaning, I thought the wires would break so I made it before :D.
And I was right: Accidentally lifted sata0_RN pad, luckly I was able to fix it making a coil with the wire, imitating a pad.


Initially it didn't boot from sata. It was caused by the uboot env variables.
Updated the "load_xxx" vars with goflexnet defaults:
setenv load_uimage 'echo loading uImage ...; load $bootdev $device $load_uimage_addr /boot/uImage'
setenv load_initrd 'echo loading uInitrd ...; load $bootdev $device $load_initrd_addr /boot/uInitrd'
setenv load_dtb 'echo loading DTB $dtb_file ...; load $bootdev $device $load_dtb_addr $dtb_file'

And it booted!

Of course, it's not only the tools, but the animal. I've been fiddlign with electronics for years.
I've burned/damaged a ton of stuff, so I know how to play with them without screwing everything up, at least not eveytime, it's never infallible! haha

I attach the 88F6281 pinout (taken from the datasheet).

Here's the sata connection.
https://i.postimg.cc/0kgj2CY8/dockstar-sata.jpg

I also marked the pci express pins, theorically you could plug any pcie device there... if there's support for it in Linux.

The board works perfectly fine either with goflex and dockstar-sata dtb. Even the led.
I upgraded to the latest version, everything works as expected, great job Bohdi!

However I noticed something, unrelated to the mod and/or the build version:
If ethernet is not attached, the serial console can't be accesed, it's stuck waiting for dhcp:
Listening on LPF/eth0/00:10:75:1a:94:3f
Sending on   LPF/eth0/00:10:75:1a:94:3f
Sending on   Socket/fallback
DHCPREQUEST for 192.168.0.15 on eth0 to 255.255.255.255 port 67
(Stays there forever)

After connecting ethernet and receiving ip, it continues and finally shows the login prompt:
[  101.379532][    C0] mv643xx_eth_port mv643xx_eth_port.0 eth0: link up, 1000 Mb/s, full duplex, flow control disabled
[  101.390189][   T17] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
...
...
Debian GNU/Linux 11 debian ttyS0

debian login:

This already happened before in the old version, 4.0.0.
It's a little annoying that Ethernet *must* connected to be able to access the device.

Not a big issue tough, I very rarely need to use the serial port.
Also, I never use dhcp for remote devices, it's a mess when the router resets the IP table, using static IP avoids the issue.

@davidalfa, wasting money? Nah, that's what hobbies are for!

Thanks for the list. Most of that stuff I already have (or suitable substitutes) and the animal is more than willing, if not capable. :-) I'm going to have to give this a try. I have a spare Dockstar I acquired for just such a project. Thanks to your photo I can also maybe trace some of the unused MPP/GPIO pins (assuming there are some) and put them to use. I connected an IR blaster and RF receiver to the TX/RX serial pins, but it would be nice to have other options.

Another small issue: The latest rootfs is missing ca-certificates and openssl.
So HTTPS downloads will fail, including the security repository in sources.list:
deb https://security.debian.org/debian-security bullseye-security main contrib non-free

I had issues trying to install openssl with the default mirror (I ran apt update first):
E: Failed to fetch http://ftp.us.debian.org/debian/pool/main/o/openssl/openssl_1.1.1k-1_armel.deb  404  Not Found [IP: 2600:3404:200:237::2 80]

I had to edit sources.list and change
ftp.us.debian.org/debian/

To: (I live in Spain)
ftp.es.debian.org/debian/

After that, the packages installed correctly.

Hmm, can't get samba faster than 34-37MB/s.
Cpu usage was quite high (~90%) so I overclocked it to 1.5GHz, no difference.

Forced the cpu to stay at 375MHz, that slowed the speed down to 16MB/s, not linear performance drop, so I think the problem isn't caused by the cpu itself, but probably I/O delay or something like that?

After few boots the bad block issue no longer happens. Maybe it's only a first boot thing after a fresh install?

That's strange. This box should not have ECC on mtd0. But as you said in the next post, it's gone after a few reboot. So not sure what to make of that. The kernel should not scan mtd0block with ECC.

This rootfs is a really basic rootfs. I've only installed some convenient packages, and let users install whatever as needed. I thought I included openssl, but I might have missed that from day one!

> ftp.es.debian.org/debian/

That a good point. I'll add some post-installation notes about apt sources in the rootfs instruction.

As far as Samba is concerned, see the Wiki thread:

And you're correct, Samba performance depends on network speed, and the HDD speed, not CPU. This box CPU (1.2Hz) is quite fast for Samba.

Note: Make sure you create a 512MB or larger swap file before running any test or install packages.

Cpu usage was quite high (~90%) so I overclocked it to 1.5GHz, no difference.

That's is suspected to be related to be the lack of swap space. This box has only 128MB RAM, or 256MB RAM for a few lucky owners!

Yup, I always use 1GB swap partition.
Hdd speed is 60/120MB/s (write/read), so that part is ok.
Tried NFS, and while the CPU usage is a lot lower, the transfer speed isn't faster.
Any tweaking ideas are welcome, but it's already pretty good, the hardware is very limited here!
