Sorry to hijack this thread, but I do have a few questions here.
I'm currently working on a mainline port for a custom board
based on the CORE9G25 SoM [1] and would like to use U-Boot SPL
instead of AT91Bootstrap. In this email, you "enable spl support"
as stated in the commit subject, but CONFIG_SPL is not enabled
for this board at any time. So only the code is present to e.g.
init the DDR2 but its actually not executed. Or am I missing
something here.
Could you please let me know, what the status of this SPL
support for the AT91SAM9X5 is? Has this been tested without
AT91Bootstrap lately?
Hi,
I did not test myself the SPL for any 9x5 board. The DDR2 init code
should be executed inside the SPL. Once you build your board with a
CONFIG_SPL enabled, you should get the spl binary built, then you can
add both SPL + U-boot proper on the boot media and have SPL boot
(execute DDR init code and load U-boot proper). I would suggest to try
on Sd-card first because it's easier (filesystem), but the commit says
only SPI and NAND tested.
On this board I only have NAND, so there is no option to first test
some other boot device unfortunately.
You can also look at the U-boot version which first included this patch,
some things may have changed since...
Sure, I can and will check this. But I first wanted to check with
you guys about the status, since you implemented and most likely
also tested this stuff.
Let me know of your findings. I will let you know if I have the chance
to test this myself.
Okay. I'll try to test this stuff (even though I don't have JTAG on
this board) and will get back to you with findings and most likely
also some further questions.
Thanks,
Stefan
