Hi all.
I have a proprietary target with an AT91SAM9263 CPU.
I have at91bootstrap running and barebox load fine.
When I try to boot the kernel it stop after Uncompressing...
Log snip:
chunk_get_cached: found 7287 in 7

booting kernel with devicetree
exitcall-> 0x23e073c0
exitcall-> 0x23e0c004
exitcall-> 0x23e415c8
Uncompressing Linux... done, booting the kernel.
The barebox commands to boot the kernel was:
$ mount -a
$ bootm /mnt/disk0.0/zImage
The zImage + barebox.bin + BOOT.BIN are all located in a 10M
FAT16 partition on the SDCARD - which allows me to use
the RomBOOT feature in AT91SAM9263.
I expect that I miss something obvious - but so far
I have failed to realize what it is.
Attached the patch I have to support the proprietary board.
It is NOT intended for upstream barebox, but attached
only if this could give someone a hint.
The kernel is 4.17-rc3 with no extra patches.
If anyone have any good ideas I am all ears.
Thanks in advance,
Sam

Subject: [PATCH 601/601] skovarm9cpu: initial support
TODO:
- display does not work.
- Seiko display timings are bogus, needs an update
- pwm is not correct

The output of bootm -v might be useful. Have you tried earlyprintk or
earlyconsole?
You have specified the memory in the devicetree. This should not
disturb, but looks unnecessary.

Nope, I will try this. Thanks for the hints.
I somehow missed the -v option to bootm yesterday but
increased the loglevel as can be seen above.

The intent is to make the DT as complete as possible, for
use by both barebox and the kernel. So in the end I have
only one DT, which is passed from barebox to the kernel.
I plan to use fixup's to select the correct display.
The timing needs to be included in panel-simple, but
using fixups allows the logic to be part of the
barebox board specific parts and not a hack in the kernel.
But let me get the kernel started first...

Hi Sascha.
> The output of bootm -v might be useful.
This setting is 'hidden' in General Setttings which is why I missed it.
> Have you tried earlyprintk or earlyconsole?
earlyprintk did the trick.
Now I can see the output of the kernel boot and can see it
bails out with a null-reference.
So all good, now I can move forward again.
