Solved: cubox-i does not boot after upgrade to bullseye
Hi,
to make the long story short:
The root cause of the new kernel not booting was that the memory addresses for
kernel and initrd.img in the u-boot environment have probably changed during
this or a previous Debian release.
A new installed bullseye system uses
kernel_addr_r=0x12000000
ramdisk_addr_r=0x13000000
fdt_addr_r=0x18000000
On the upgraded system
kernel_addr_r=0x10800000
ramdisk_addr_r=0x11800000
fdt_addr_r=0x18000000
was used. Changing these variable to the new values fixed the issue. Many
thanks for all the advice I got.
I assume this is because the u-boot environment variables are not changed
during an upgrade of u-boot or to a new Debian release.
Judging from the upgrade typescripts, the system was originally installed with
Jessie (Debian 8).
The u-boot environment variables of the newly installed system are very
different from the ones in the upgraded system.
Is there an easy way to copy all the u-boot environment variables from the old
system to the new system?
Does SPL get upgraded with the u-boot upgrade?
I summarized my learnings in the Debian Wiki:
https://wiki.debian.org/InstallingDebianOn/SolidRun/CuBox-i#Boot_Process
and checked it on a second cubox-i device.
I think it would be useful if somebody would read through it and confirm that
there are not grave issues in the description.
Many thanks
Rainer
