[A370] Porting to Shuttle KD22

For Developers
1

Hello there!

Does any of you have some experience with non-supported devices using Marvell's Armada 370 SoC?
Unfortunately this device has an unpopulated serial port, which makes me aware of doing anything unsure.
This NAS is really similar to Buffalo LS421. Let me share all the information I have at the moment.

  • Marvell 88F6707
  • 512MB DDR3
  • unpopulated serial port
  • 128 MB Hynix NAND (HY27U1G8F2BTR)
  • 1MB SPI for U-boot 2009.08 (build: 2013.07.31 Marvell version: 1.1.3 NQ)
  • uImage name: "linux-armv7-mirabox"
  • console=ttyS0,115200 root=ubi0:rootfs ubi.mtd=3,2048 initrd=0x12000000 rootfstype=ubifs

I think, that would be a safe way to modify the NANDProfile for Mirabox (target/linux/mvebu/image/Makefile) according the Hynix NAND's datasheet.
However the U-boot seems to be the main thing here, without access to the serial console or clunc I should somehow modify the boot parameters.

@daniel @Kaloz @danitool to your attention please

For the initial port you will need serial access (or REALLY know what you are doing and be ready to add serial access if needed).

DISCLAIMER: what I say below is a suggestion, while this is true for most devices it may not be true for yours. If you attempt what I tell you you do so at your own risk.

By "serial port" you mean 4 pins, not RS-232 serial (that has much more than 4 pins), right? What tells you it is a serial port? Is it written on the board?

Since it is an Armada 370 it should be a 3.3v UART.
I think you can populate it, identify the power pin with a multimeter (this should tell you if it is 3.3 or 5v), then cover this pin and NOT use it.
I think you should also be able to find the Ground pin with the multimeter too.

Then you can try blind the other pins with an UART adapter that can do 3.3v/5v (most "arduino" UART-USB adapters can do it).
As long as you are NOT connecting to the power pin it should be safe, the worst that can happen is you get garbage on the terminal screen. If that happens just swap the data pins on the serial port.

You already know the speed is 115200 and other parameters are most likely default like for all other devices.

I just managed to get serial port working (yes, it's a 3.3 volts UART).
The 19.07 Mirabox initrd just boots fine, however I need to work on the dts file. Something really softly just triggers the pc speaker :slight_smile:

@daniel, how did you manage to discover the GPIO mapping?

7

I discover GPIOs manually by exporting them through /sys/class/gpio/export and then toggle output value to find LEDs, then toggle mode and read input value to discover buttons.

Hey.

I'm planning on fiddling around with my KD22 and OpenWrt, but I can't find the original firmware anywhere anymore.
The official source that got linked at the hardware data page isn't up anymore and a google search didn't bring up any matches :frowning_face:

Any of you know where i could get the firmware from?
Maybe, by any chance, someone of you could provide the file in case there are no other official sources. @daniel @vinibali

Thanks in advance. :slightly_smiling_face:

use the wayback machine (web archive) http://web.archive.org/ just copy the dead link in it and see if it has old versions saved.

Seems like that file was saved to web archive in 2014, so use link below
http://web.archive.org/web/20140903094608/http://download.shuttle.eu/Mirror/NAS/KD22/Firmware/OMNINAS-KD22_2.02.20140721.TAR.GZ

I didn't know they even got old file URLs / archived the files there.
Wow. Thanks a lot, today I learnt.

11

Back in the day I spent some hours with that.
It's salted with OpenSSL, but the key which can be found on the rooted system doesn't work.
That would be easier to root the device and save the files/partitions from that.
I'm so busy these days, but as I mentioned at the TOH, it can be booted with the Mirabox image.
I also had some mails with the European support team, they are unable to provide the kernel sources for some reason.

The Shuttle KS10 seems to be a single disk KD22. It has the same SoC (yet a lower clock) and half the RAM.

Yet I can't boot the Mirabox initramfs kernel, it stops at

Starting kernel ...

I have tried the 21.01.1 and 19.07.8 images, and I have tried marvell_a370-db and marvell_a370-rd (what is the difference?), further I have tried to add earlyprintk (next to the existing console= argument) to the command line.
Any suggestions?
Stock kernel boots fine, btw.

13

How are you booting the image? Tftpboot?

With so little in the log I can only make guesses but it could be;
Tftp image load address
Image is too large for the 2009 uboot to handle (try a plain uImage file)
Dts in the image is not compatible, possibly due to ram layout

14

Yes, tftpboot.

As you can see the stock uImage 3.3MiB, while initramfs-kernel 19.02 is 3.9MiB. If there is a size problem I'd expect it at >4MiB.

What do you mean by that? This box has half the ram, but I suppose the uncompressing piggyback shouldn't detect/care about that. So at least I'd expect a 'Uncompressing the kernel'.

15

Hi,
A hard lockup without a decompression or crc error points to a fundamental incompatibility between the image being loaded and the board. I suggest memory as manufacturers can setup memory specs very differently between boards and the dts used must allow for them.

The dts differences can be much more than just setting how many mb of ram the board has.

Here's what can happen with Marvell devices when the kernel / dts don't match what the manufacturer intended; https://forum.doozan.com/read.php?2,32146,106944#msg-106944
For 370s with old uBoot you can hit a memory conflict and then - crash.

Changing the image load address in the uBoot parameters may overcome a conflict. You could increment it up to 4000000 and load at 80000 to see if it gets further. I'm not hopeful though.

Again, with so little output its hard to debug. Isolate what you can and see if you get any further. Start with extracting the uImage from the initramfs image and tftpboot that. If it still locks hard then the mirabox image is fundamentally incompatible.

As there are no other A370 boxes supported by OpenWRT, perhaps try the A370 kernel on the doozan forum. Those guys have both 'old uBoot' and modern uBoot kernels for this SOC.

And the full stock bootlog could be interesting, may point out what differs from the KD22.

16

Ah, thanks for that. I have read that post of bodhi, and although I don't get what actually is happening, I get that u-boot can initialize something in different ways.
Below I put the full bootlog. When comparing it to the stock bootlog of the KD22 in the wiki, I didn't see any unexpected differences. (Except that the KS10 boots faster, according to it's own timing. But as there is a jump of almost 5 seconds, maybe just the clocksource is not reliable on boot).
I'll try the uImages from doozan.

I've had a look at all the mainline Linux 370 dts and frustratingly there are no other mainlined devices with 256meg of ram. Either devices like this are very rare or there's something unique required to make a 256meg device work.

Attached is an alternate OpenWRT kernel for an A370 reference board. Worth trying as it is smaller than a full initramfs image.

However I expect you will need to jump straight to creating your own dts specifying the correct memory size.

If you look at how the Linux kernel is setting up the memory on your box compared to the KD22 there are some differences in the vmalloc and modules, though I do not know whether that's important!

I think so, fixing the DTS and build the new image is something what I would like to try first!

Thanks. Your uImage doesn't boot either. However, the 'special' bohdi kernel combined with the Mirabox dtb file, boots. Bootlog appended.
Interesting is that the kernel knows the memory size:

[    0.000000][    T0] Memory: 242556K/262144K available (10240K kernel code, 1479K rwdata, 3000K rodata, 1024K init, 362K bss, 19588K reserved, 0K cma-reserved, 0K highmem)

while the Mirabox has 1GiB. So I'll have to find out what is special about this kernel (or simply use bohdi's), and find out if I can adapt the Mirabox dtb to match the KS10.

/Edit:
I compared the config files of the 'normal' bohdi kernel and the 'special' one, and apart from some multicore stuff, and 'not set' in one, and not mentioned at all in the other, this might be the most striking difference:

-CONFIG_DEBUG_UART_PHYS=0xd0012000
-CONFIG_DEBUG_UART_VIRT=0xfec12000
+CONFIG_DEBUG_UART_PHYS=0xf1012000
+CONFIG_DEBUG_UART_VIRT=0xfed12000

Obviously if this is the difference there is no serial out (although I thought that the earlyprintk used u-boot function pointers to log), and it will probably crash. Or are these the u-boot function pointers? Google doesn't come with much information about these config values.

Hi, that appears to be how he’s stopping Linux from conflicting with the a370 uboot uart config and memory ranges.
If adding it to openwrt gets the kernel to boot then that’ll be a win.
