Since I'd be chainloading barebox from the existing U-Boot, which does
support loadb and bootm, it probably makes the most sense initially to
just skip the lowlevel init, and build a minimal ARM second stage, and
wrap it in a u-boot image, I think.
I tried using the at91sam9263ek_defconfig, and unsetting
My CROSS_COMPILE env variable was set to:
I then made it into a uImage using:
mkimage -A arm -O u-boot -T kernel -C none -a 0x800000 -e 0x800000 -n
"Barebox" -d barebox.bin uImage.bin
Unfortunately, it hung as soon as I tried to execute it in U-Boot:
## Booting image at 00100000 ...
Image Name: Barebox
Image Type: ARM U-Boot Kernel Image (uncompressed)
Data Size: 176100 Bytes = 172 kB
Load Address: 00800000
Entry Point: 00800000
Verifying Checksum ... OK
Starting kernel ...
Any suggestions for a better (minimal?) defconfig to start from, or
other things to try?
