testing barebox on calao sbc35-a9260 board

testing barebox on calao sbc35-a9260 board

[Belisko Marek]

Hi,

I have a calao board sbc35-a9260 with u-boot pre-installed on it.
I would like to try barebox running on that board (also make some development).
I build at91sam9260ek_defconfig to try it out. I became to situation
that I don't know how to load image to board :)

I try via tftp but u-boot automatically try to boot it and I got some
error about magic number.
I think about possibility just download binary to some RAM address and
then use go command in u-boot
to test if barebox binary will work.

There exist some how-to or example how to do this?

Thanks in advance,

Marek

It's perfectly fine to start barebox from U-Boot with the 'go' command.
Try 'setenv autostart no' in U-Boot to stop U-Boot from autostarting
images.

Is there a way to do the same on Barebox? Currently 'go barebox.bin' in ramfs 
returns -EINVAL from memmap.

I disable autostart and download barebox image to 0x8000 with
tftp 0x8000 barebox.bin and then jut go 0x8000 ended with:
## Starting application at 0x00008000 ...

Same I got when load latest compiled u-boot binary.

For compilation I used Codesourcery eabi toolchain arm-2009q3
with at91sam9260ek_defconfig.

Could I somehow check (without JTAG :)) if image is compiled OK
and could start on board?

if I remember well, on AT91 SDRAM is at 0x20000000 so actually you don't 
seem to load it in SDRAM.
For the binary to execute properly, you should load it at the right 
target address in SDRAM.

If barebox detects its current runtime address differs from the link address 
it copies itself to the link address first.

So writing it anywhere into sdram should work. But only, if also the link 
address is in the sdram area...

Seems it's not working in my case. U-boot code just jump to address which
is taken as argument according code. If barebox is copied to correct link
address and started it should work. Is there any possibility to check
link address from binary
or it's not necessary to use mkimage tool from u-boot?

Here are the necessary steps to run the barebox.bin file from U-Boot:

tftp 0x20000000 barebox.bin
go 0x20000000

As Eric stated the 9260 has SDRAM at 0x20000000, so this would be an
appropriate load address. barebox then relocates itself to 0x23f00000
according to the link address which you can check by doing 'make
barebox.S' and looking at barebox.S.

If stored in a file it is indeed not runnable as the file is fragmented
in memory. It would be possible to copy it to a linear memory to memmap
it, but currently this is not implemented and I'm not sure this is a
good idea. It's possible to do a 'tftp barebox.bin /dev/ram0; go
/dev/ram0' instead. (or 'memcpy -s barebox.bin <sdramadr> 0x0 <size>; go
<sdramadr> if the file is already in the filesystem)

U-Boot binaries compiled for starting from flash are usually not
suitable to be run as second stage from SDRAM. Most of the time
it requires at least a include/config.h tweaking.

Following steps give me the also only Starting application at
0x20000000 and nothing more.

Yes it seems link address ( 0x23f00000) is correct according barebox.S file.
Strange.

Anyway thanks for support and advices.
