booting pandaboard rev A2 problems

booting pandaboard rev A2 problems

[Belisko Marek]

Hi,

I'm trying to boot barebox on Panda rev. A2.

I make panda_xload_defconfig compile and put to FAT SD card partition
ranamed barebox.bin to u-boot.bin (MLO reads u-boot.bin by default).

Barebox start but after printing revision number is stuck. I add some
printks and
seems it hang in omap_hsmmc_probe funtion after mci_register(&hsmmc->mci) call.

I try with 2 SD cards and non of them is working.

Also try to load to flash partition only barebox.bin.itf + barebox.bin
but this setup also
doesn't work. AFAIU itf add some data before barebox to be possible to
boot directly without
x-loader. When run_shell is called barebox.bin should be copied do
DDRAM and run.

Any ideas what should I check.

Thanks in advance,

marek

build barebox.bin.itf with panda_xload_defconfig and rename it MLO
build barebox.bin with panda_defconfig and copy it to sdcard

So it boot till barebox.bin not found. Reducing the size of MLO fix that 
for me. I send a patch for panda_xload_defconfig

Hm, I don't know the revision of our panda board. I'll have a look
later, it may be different.

I'm a bit confused. The binary resulting from xload_defconfig is
supposed to replace MLO.  There are two panda defconfig in the tree, one
for xloader replacement and one regular full blown config.

Ok, let's try to sort things a bit.
does panda_xload_defconfig barebox.bin.itf copied as MLO to the SD card
produce any output?
Does panda_defconfig copied as u-boot.bin to the SD card work or does it
behave like you described above?

Well I create barebox.bin.itf with xloader_defconfig copy to SD card
renamed to MLO.
Create barebox.bin copy to SD card.
Output which I got is:

barebox 2011.04.0-00158-g2153636-dirty (Jun 20 2011 - 19:50:23)

Board: Texas Instrument's Panda
PandaBoard Revision: 003
omap_mmc_probe <- debug where it just hang.

@Jan: Which board revision you have?
I have bad feeling it has something to do with SD cards which I have?

Thanks for replies.

Just checked, our panda is rev c3. Maybe you should hunt for differences
in the lowlevel startup code in TIs Xloader which I have not proted
correctly to barebox.
