[A370] Porting to Shuttle KD22

For Developers
21

Meanwhile I know what the u-boot uart conflict is. On older Marvel SoC's the serial port was initialized by u-boot to use address 0xf1012000. But the first u-boot for the Armada 370 initialized them on 0xd0012000. Later that was changed back to 0xf1012000. That is no problem, as it is specified in the dts file.
But if you enable the EARLY_PRINTK in the kernel config, the kernel will start printing before the dtd file is read, and so the address has to be hardcoded in the kernel. As bohdi enables EARLY_PRINTK in his kernels, he has to provide different kernels for old and new Armada 370 boxes.
On OpenWrt this flag is by default not enabled, so having the correct address in the dtb file is enough. That is why the Mirabox dtb file worked for the KD22, they both have a 1st generation u-boot. (BTW, the Mirabox dtb doesn't enable the SATA ports, so that KD22 is a bit crippled), and my KS10 should have worked either. But it didn't.

The problem is target/linux/mvebu/patches-5.10/300-mvebu-Mangle-bootloader-s-kernel-arguments.patch. If I remove that, the uImage boots on my KS10. But reading that patch it's not clear to me why it would keep my KS10 from booting, and not the KD22. At this level there should be no difference.

Now I have a working dts file for my KS10, which seems to be complete. I'd like to attach it here, as it is a good start for a KD22 dts, but attaching files other than images is not possible?

/Edit: With try and error I have found that the patch disables the transfer of the bootloader provided memory size in ATAGS to fdt in function atags_to_ftd() in atags_to_fdt.c in the decompressing piggyback, which causes the crash.
I have to try if putting the right memory size in the dtb file solves this.

/Edit2: It does.

And now I have wifi problems. The board has an mini-pci slot with a Realtek wifi card:

01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

I have build a kernel-initramfs with (I think) the right support for that:

But if I try to use it:

Bringing it up makes the box reboot. Not immediately, but after several seconds. Simply executing reboot is much faster.

# ip set link dev wlan0 up

So what is going on? If I included the wrong wifi driver/firmware modules, I think it would be ignored. When I boot the box to Debian, with it's udev, I get

After that I have 5 interfaces:

And I can bring it up:

Unfortunately I don't know how to test the wifi in firmware. The only wireless command I can find is iwpriv, which isn't very useful, without further documentation.
Maybe interesting, when I bring one of the wlan0-va? interfaces up, they bring up an access point:

Suggestions?

I would forget about Realtek WLAN chipsets (yes, their PCI(e) department isn't quite as bad as the USB side of the company (Reasil), still - just don't…).

New problem. Managed to build an kernel-initramfs and a squashfs-sysupgrade. The kernel-initramfs boots fine, everything seems to work, but sysupgrade silently fails. From the documentation I understood that the partitions kernel and rootfs would automagically be used, when available.
The partition table at the moment is

root@OpenWrt:/# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00800000 00020000 "kernel"
mtd1: 00600000 00020000 "initrd"
mtd2: 07200000 00020000 "rootfs"
mtd3: 000c0000 00010000 "u-boot"
mtd4: 00010000 00010000 "u-boot-env"
mtd5: 00030000 00010000 "unused"

where mtd0-2 is nand, and mtd3-5 is nor. At the moment kernel-initramfs is flashed in mtd0 (I'm trying to install without serial access, although I have that, and this is a intermediate stage).
When trying to sysupgrade, it behaves normal (as in, closes all daemons and reboots) but after reboot still the kernel-initramfs is active.
Maybe there is something wrong with drivers? From dmesg:

Tried to rename rootfs to ubi (with no other reason than that is the rootfs name on my router) but that didn't help either.

26

@Mijzelf, do you have any update on your machine now?
I would like to test the KD10 dtb file on my KD22. Can you share it?

27

I gave up on OpenWrt on this box, couldn't get sysupgrade to work. It's running Debian now, and loads uImage and uInitrd from harddisk. (Takes a full minute, but who cares)
And yes you can have my dts file, you can find it attached here.

28

Thanks, I've found it in the meanwhile :slight_smile:
I don't think, a missing upgrade is a so big thing.
How much space a bare system takes on you flashdrive?

29

There is no flashdrive. Just a classic harddisk. The rootfs is 2.4GB, but I didn't try to keep it lean.

30

Hi @vinibali, based on the info available I compiled a firmware for the KD22:
openwrt-shuttle_kd22.zip

To install the firmware (on your own risk):

  1. Boot via via tftp the initrd image:
    tftpboot 0x1200000 openwrt-kd22-initramfs-kernel.bin
    bootm 0x1200000
  2. Once booted, transfer the sysupgrade image to the device, and perform a sysupgrade:
    sysupgrade -n openwrt-kd22-squashfs-sysupgrade.bin
  3. Wait until it finish, and ssh to 192.168.1.1

I noticed there is a paramenter in the uboot env which may mangle the kernel loading:
load0=nand read.e 0x02000000 0 360000
Probably, with this config, it is only able to load 0x360000 bytes = 3.4 MiB.

You may need to increase this size if possible via Uboot command line. If not possible, then we could split the kernel in two parts to flash the second one on the initrd partition.

31

I was playing with the sources so far this day.
And I managed to modify the Buffalo LS421DE's dts and device values to get a bootable build with working:

  • ethernet (need to change to the ethernet device to ge0_rgmii_pins in dts)
  • sata
    It's able to handle the disks too, but I cannot make the rootfs work.
    I would say the KS10 dts is pretty unusable this case, it's even has the rattling trigger sound on the pc speaker.
32

This is the patch I've used for my own compilation

The buzzer probably is controlled by a gpio.

This is the script I used long time ago for finding gpios in my Linkstation:

#!/bin/sh
 
GPIOBASE=`cat /sys/class/gpio/gpiochip*/base | head -n1`
GPIOmin=`expr $1 + $GPIOBASE`
GPIOmax=`expr $2 + $GPIOBASE`
nums=`seq $GPIOmin $GPIOmax` 
 
cd /sys/class/gpio
for i in $nums; do
echo $i > export; echo out >gpio$i/direction
done
 
while true; do
  for i in $nums; do
     echo 0 > gpio$i/value
 done
  sleep 1
  for i in $nums; do
     echo 1 > gpio$i/value
  done
  sleep 1
done

It toggles (blinks) gpios between min and max range of gpios, with an interval of 1 second.

Let me share my latest experiences so far:
The useable size of the kernel is limited to some 6,1 MB, at least this is what U-boot can loads, otherwise the partition itself is 8MB. This is how the serial output looks like in this case:

Shuttle>> bootm 0x2000000
## Booting kernel from Legacy Image at 02000000 ...
   Image Name:   ARM OpenWrt Linux-5.10.161
   Created:      2023-01-03   0:24:21 UTC
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    6497722 Bytes =  6.2 MB
   Load Address: 00008000
   Entry Point:  00008000
   Verifying Checksum ... OK
   Loading Kernel Image ...
<SYSTEM HALTS>

So I managed to build a somewhat usable image within this size, however we might need to split up the kernel and initrd.
What could be the resolution for the rootfs? Currently the bootargs are overwritten with the dummy values, however I cannot mount the manually created squashfs filesystem because of the missing compression algorithm. It doesn't matter if I use gzip, xz or zstd.

[  444.953077] Filesystem uses "zlib" compression. This is not supported
[  695.521651] Filesystem uses "zstd" compression. This is not supported

Another problem is that, we should pack inside the static configuration for the network interface, however we should use dhcp here. What would be a solution for this?
Another question, how should I build the images for have effect at the makefile changes?
It seems, I need to do a make distclean, but after that another build took 40 minutes on my 8 thread Ryzen machine on tmpfs.

can you post the bootlog?

Yep, sure. With your dts the UART TX doesn't seem to work.

Your mtd NAND partitions are wrong

[ 1.212947] 0x000000000000-0x000000800000 : "kernel"
[ 1.219060] 0x000000800000-0x000000e00000 : "initrd"
[ 1.224794] 0x000001400000-0x000008600000 : "rootfs"
[ 1.229853] mtd: partition "rootfs" extends beyond the end of device "pxa3xx_nand-0" -- size truncated to 0x6c00000

Since this is a NAND device you should use ubi for rootfs. You didn't define the correct size for partitions..

I fixed the serial console in my build (probably earlycon is broken afterall). Can you test it?: openwrt-shuttle_kd22.zip

BTW I'm not sure how do you install the firmware in your device, I assumed you use sysupgrade and the kernel is stored in the partition as raw data. Whereas in the Linkstation the kernel was stored as a file into a jffs2 filesystem.

37

So it appears a KS10 is not a singledisk KD22, but another box which just happens to have the same SoC? Can you share a picture of the PCB?

it's on the TOH page:

thanks, i found the misconfigured partition details in the meanwhile.

I didn't know that, thanks for that.

No , that's still not working. I don't really have a clue why it's failing. As long as we use a static configuration for the network interface and i don't have a rootfs, I'll need the console.

I used to use mtd write for that.

Indeed it's a complete different design. For reference I'll attach the PCB photo's of the KS10.

From the looks it seems the KS10 has a shorter housing.
