[U-Boot] am335x_evm_usbspl_defconfig testint
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

Hi, I'm porting BBBlfs bootloader server to nodejs. Now, after receiving tftp request for SPL, I'm transferring SPL. I built spl/uboot with config am335x_evm_usbspl_defconfig . After SPL transfer it fails to boot, here's the serial output:
U-Boot SPL 2017.07-rc1-00163-g8cb3ce6 (Jun 11 2017 - 01:09:02) SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
Please help me to debug this problem. Code for server: https://github.com/ravikp7/node-beagle-boot Thanks Ravi

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: https://pastebin.com/MbKfB7bF
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/
I forgot to follow that up and looks like it did not make into the u-boot master branch.
