Unbricking Dockstar (1 reply)

Hi,

I recently dug up an old Dockstar device, still in original packaging.
Unfortunately, it does not boot any more. The device gets stuck in U-boot and using a serial cable, I could see that the kernel it tries to load from flash has a checksum error.

I tried several ways to get into a Linux environment to be able to flash a newer U-boot, but none has worked, yet.
I tried:
- Downloading a newer U-boot to chain load (uboot.2017.07-tld-1.dockstar.mtd0.kwb)
-> fails with no output after 'go 800200'

- Downloading kernel and ramdisk created from 5.19.2-kirkwood-tld-1-bodhi, using original /dev/mtdblock2 as rootfs
-> Kernel starts, but rootfs can't be mounted (no driver)

- Downloading kernel and ramdisk created from 5.19.2-kirkwood-tld-1-bodhi, using original /dev/sda1 (USB) as rootfs
-> Kernel starts, but rootfs can't be mounted (device not found)

I'm hesitating to just flash the above U-boot to mtd0, as it doesn't start when chain loading.

Any ideas how to bring my Dockstar back from zombie land?

Thanks
Tom
