Re: WD MyCloud Gen2 (Glacier, Armada 375) - 2 months ago

Hi Bodhi Please take a look at https://fox-exe.ru/WDMyCloud/WDMyCloud-Gen2/Photo/Top.jpg This board do not have separate network chip(also on back side), it uses "integrated GbE PHY" which is detected as "generic". Also, as it works, it shouldn't worry us too much if it has (or not) some magic Marvell ID as long as there's no known issues/other revisions of

I could not find GPL sourcecode for v5 firmare, but older versions are here (https://community.wd.com/t/wd-my-cloud-v3-x-v4-x-and-v2-x-firmware-versions-download-links/148533) I attached kernel from latest WD firmware, maybe you can extract DTB https://1drv.ms/u/c/3db6dd30f94c5b17/EZF674mKxdBJspMflZRSc58BuPMkCSovFsMePFis_sra6Q?e=dK3Dtn

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 2 months ago

Hi! AFAIR 6.3.8 is the latest kernel i have tested. Should i try newer kernels to find latest "compatible" or just any working bootlog? Or maybe You need bootlog from original firmware?

Hi Bodhi, any progress with uboot/kwboot on this platform?

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 1 year ago

Old (debian 10) kwboot does not work, but kwboot 2024.04-rc3 works just fine with backup. Funny (strange?) thing is that even changing order of kwboot parameters can cause upload errors Here's successful (not interrupted by user and without drive connected) bootlog ./kwboot -t -b backup_wd.bin -B 115200 /dev/ttyUSB0 kwboot version 2024.04-rc3-00001-g0861eab8ec-dirty Detected kwbim

Hi I'm probably the only user of bodhi's kernel on this box, but i just want to let you know I just tested linux-6.3.8 kernel and it fits into 5MB limit and boots just fine. I looked at sizes of all 6.x kernels and they should fit too

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 3 years ago

Bodhi, it looks this problem was for a longer time, but i didn't paid attention. I'll dig deeper to find out if first supported kernels (5.2/5.3?) had this issue or it is related with changing compression to xz. There's no u-boot source code in wd's gpl sources.

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 3 years ago

> like we'll keep it smaller than 5MB easily. Sounds great. Please, make sure all marvel sata + ext3/4 drivers are built into kernel. I found, that initrd is loaded into memory, but is not used - looks like kernel is overwriting some memory regions (on decompression?) and uses drivers from root partition. For that reason default debian 11 kernel/initrd cannot be used to boot on wd

Hi, Kernel 5.13.17 segfaults with CONFIG_MVPP2_PTP enabled, so for now disabling it would be necessary. I'm not sure if next kernel will fit into 5MB size limit, so this might be the last working kernel for this box
by osa - Debian

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 3 years ago

Hi It looks that your 5.12 and 5.13 configs have CONFIG_MVPP2_PTP enabled. Kernel 5.13.17 boots fine when CONFIG_MVPP2_PTP is disabled. Need to investigate later if latest changes to drivers/net/ethernet/marvell/mvpp2 will allow to boot with CONFIG_MVPP2_PTP enabled.

It's still work in progress https://translate.google.com/translate?sl=pl&tl=en&u=http://osowiecki.net/debian-na-wd-my-cloud-2-gen/ I believe all that stuff can be run as a single script so probably easiest way to install. Now it's time to write recovery manuals ;-) Comments and suggestions are appreciated

Hi With every little f*** up i learn something new I found new version of u-boot in gpl source code (binary only) and... got simple flash programmer to fix broken flash ;-) I don't know if they differ somehow, but there's no setenv but bootargs trick works. Is it possible to convert u-boot bin to kwb file? Is it possible to change some internal string values and recalculate

Re: WD MyCloud Gen2 (Glacier, Armada 375) - 4 years ago

Hi Still no luck. I splitted flash to u-boot and env parts and nothing really changed. fw_printent shows some values even if env partition is empty.. maybe it reads whole mtd to find some headers? AFAIR mtd partitioning can be made in fdt. But this is not the case now I think in autoboot mode nearly all envs are ignored and only bootargs are properly passed. In manual mode envs are p

Hi I reset/restore nand to factory state.

Hi, i managed to compile 5.10 xz compressed kernel and it fits to 5MB limit and boots nicely. What are downsides of switching to xz compression? Some envs are hardcoded and overwrites envs like bootcmd (even if CRC is correct) Luckily setting bootargs root=/dev/sda2 console=ttyS0,115200 is persistent and it is enough to boot debian kernel from boot partition (sda3) and use sda2 as root

Hi I found latest kernels (5.5+ ???) are over 5MB and they do not fit into hardcoded adresses in u-boot Kernel is loaded at 0xa00000 and initrd is loaded at 0xf00000 so maximum kernel size is 5 242 880 bytes (with mkimage headers) Is it possible to fit into that limit by moving some modules to initrd in next releases?
