2 years ago That does not look too bad. Kernel boots, but can't find rootfs. You might want to load the uRamdisk from this repo, or create your own one. Try using fatload to load the uRamdisk and then bootm <kernel> <ramdisk> to boot. Even if the ramdisk fails to mount a root system it would then give you an emergency prompt. Check this file for reference https://github.com/Heisath/wdmc2-kernel/blob/master/build_initramfs.sh

2 years ago Thank you :). I tried it in both ways, loading the kernel and ramdisk somwhere in memory and starting it, but it always started the nand memory with the original software. What am I doing wrong? :)

Verifying Checksum ... Bad Data CRCThe "bad data crc" is the hint. I assume you are using two memory locations to close together. They are overwriting each other. Also remember that it needs to be high enough not to interfere when the kernel/ramdisk is unpacked.
The original rescue firmware gives you good spots to load: 0x00a00000 for kernel and 0x00e00000 for ramdisk.

---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) ]---no emergency console available at that point, sadly. Looks like it does not get the USB stick?

2 years ago Nah the usb stick is not the problem at this point. After you load the images in uboot it does not matter. There is still something wrong with detecting the ramdisk:
Trying to unpack rootfs image as initramfs...
rootfs image is not initramfs (invalid magic at start of compressed archive); looks like an initrdand RAMDISK: Couldn't find valid RAM disk image starting at 0.
I can just suggest to fiddle further with the values, or try the various ramdisks available where you got the dts. Or you could try to boot your kernel with the vendor rescue ramdisk.

2 years ago I played around with it and could find an old ram disk ( https://wd.hides.su/fox_exe/WDMyCloud-Mirror-Gen2/Debian/Dev/uRamdisk ) - with this one I can load some kernels. But it looks like I encounter the same error as #8 - I can boot to a Ramdisk with 5.10 kernel, but newer ones give the same error as above. Looks like there is some issue with uBoot?

2 years ago Yeah I just realized your kernel is at 4.1MiB already... Try to disable some functionality, move stuff to modules or select "Optimize for size" instead of performance...

2 years ago Hey there, I got it working! The real problem was the defunct uBoot on the WDMyCloudMirror Gen2, which needed to be patched. Thanks for all your help, I wrote everything together in this blog post: https://www.nico-maas.de/?p=2469 - and secured the most important files here: https://github.com/nmaas87/WDMCMG2 Also, you might like to try compiling the kernel with these changes:
remove:
CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE=y
add:
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
CONFIG_TRIM_UNUSED_KSYMS=y
CONFIG_UNUSED_KSYMS_WHITELIST=""the last two commands should remove a lot of debug symbols and further slim down the kernel :)

2 years ago Cool. Maybe I will integrate this at some point. Might need a MyCloud Mirror to test first though.
Hey there, awesome repo! I have an WD MyCloud Mirror Gen.2 and wanted to ask if it would be possible to add support for that ARMADA-385 device? I got the needed dts from here: https://wd.hides.su/wdnas.el8.website/Other/Official_linux_kernel/uImage-armada-385-wdmc-mirror-gen2 And copied an older v5.10.109 kernel config from here: https://github.com/gisab/WDMC-Ex2/blob/main/3.Kernel/kernel.config
I overwrote the normal wdmc2-kernel dts file with the WDMCM2 one and the linux-5.15.y.config with the older kernel config. Obviously I kept the file names the same as the original git files here :)
I created an USB 2 stick with FAT32 and EXT4 partition. I copied the content of the in output created boot-5.15.45.tar.gz to the boot/first partition (which now has a boot folder in it and then the files) and the output of the output/rootfs/ to the root/second partition.
As the WD does not boot from the stick (it got 2 USB 3.0 ports), I put the stick in the first / correct on and attach via UART, stop autoboot, load usb via
usb reset, list the first partitionfatls usb 0:1and set the uimage for boot withfatload usb 0:1 0x500000 /boot/uimagethen start withbootm 0x500000sadly this happens:
Any idea on how to get this fixed?
