[U-Boot] am335x_evm_usbspl_defconfig testint

[Jason Kridner]

Stefan,

I see you submitted this defconfig:
https://lists.denx.de/pipermail/u-boot/2016-November/272425.html

I have a Google Summer of Code student intern attempting to use it and he's
seeing it hang without entering UMS mode. Details are below.

Can you give any advice on how you tested this?

I believe he still needs to do something to explicitly enable UMS. Can you
confirm?

Ravi,

If Stefan cannot answer, I'd suggest adjusting the default boot command to
invoke UMS. Have you been able to stop the boot process using the serial
port and get to the u-boot console? At the console, have you tried running
the 'ums' command?

Regards,
Jason

But SPL isn't booting first :(

Yes, I tried running ums command from console, => ums 0 mmc 1 and the emmc 
was mounted as mass storage device.

It was a configuration issue. I sent a patch to the U-Boot mailinglist.

Should see it after it approved by the moderator.

The problem was earlier in the boot than this.

Here is a pastebin after the configuration changes were applied:

He should be back in business.

Could you try this patch that I posted sometime back:
https://patchwork.ozlabs.org/patch/748877/

I forgot to follow that up and looks like it did not make into the
u-boot master branch.

Were you able to get this to compile and fit in the SRAM?

With the latest U-Boot and your patch I get the following on compile:
arm-poky-linux-gnueabi-ld.bfd: u-boot-spl section `.rodata' will not fit in region `.sram'
arm-poky-linux-gnueabi-ld.bfd: region `.sram' overflowed by 9928 bytes
scripts/Makefile.spl:333: recipe for target 'spl/u-boot-spl' failed
make[1]: *** [spl/u-boot-spl] Error 1
Makefile:1382: recipe for target 'spl/u-boot-spl' failed
make: *** [spl/u-boot-spl] Error 2

I had to remove some of the other features to get it to fit in SRAM.

Here is the patch that I sent yesterday:
https://patchwork.ozlabs.org/patch/774899/
