LS1021a SD card boot issues

jtice — Fri, 31 Jul 2015 15:16:40 GMT

Hello,

I have an LS1021A-TWR that I'd like use to run Linux from an SD card, but I'm having trouble getting it to work. First, I tried using the QorIQ SDK 1.7 to build everything and flashed to an SD card, but when booting it has a kernel panic that appears very similar to this one. It appears the author of that post fixed his issue by using u-boot 2015.01, but after flashing both mainline 2015.01 and 2015.04, I can't seem to use the "ext2load" command anymore as it says "Unknown command 'ext2load' - try 'help' ". I don't have much experience with u-boot and embedded systems, so I'm not sure if there is some configuration required when building u-boot to enable ext2load or if there's another way I should be configuring u-boot to read the kernel and dtb files from the SD card. Any help is appreciated, thanks!

Why don't you use uboot image from SDK 1.8? ext2load is working fine on that.

Hi Adrian,

I have actually tried using uboot from 1.8, but unfortunately that was even less successful for me. Like in 1.7, I changed the config to build uboot for an SD card and ran bitbake, but absolutely nothing shows up from the uart on minicom after flashing this image and connecting to power. Should the process for building or flashing uboot be any different from SDK 1.7 to 1.8?

Attached you can find uboot built for sd boot from sdk 1.8. Also, make sure this image was written a correct address in sd-card. Below you can find two ways to write uboot on sd card:

from u-boot

$ tftp <address> /<path_to_uboot>/u-boot-sd.bin

$ mmc write <address> 8 0x400

from linux

$ sudo dd if=/<path_to_uboot>/u-boot-sd.bin of=/dev/mmcblk0 bs=512 seek=8 conv=notrunc oflag=sync

Not sure what was wrong with the uboot I built with sdk 1.8, but the one you attached seems to boot with similar issues as with 1.7's uboot. After connecting to power, I see the following:

Could you please add also the uboot printenv output? Also, did you use uImage from sdk 1.8?

Sure:

Also, I've used the uImages from both sdk 1.7 and sdk 1.8 and had the same error messages. I've also used the actual file names for both the kernel and dtb instead of the symbolic link, but it seems to have no effect.

I can confirm you that using images from SDK 1.8, sdcard boot works fine. Check the sd to be coretly formatted and in bootargs make sure partition is available on sd (/dev/mmcblk0p2).
