i.MX6SoloLite Evaluation Kit u-boot build and test issues

I'm trying to create a SD card image for the i.MX6SoloLite Evaluation Kit using the binaries that I build from ltib. I'm using L3.0.35_4.1.0_130816_source. After the ltib build completed, things looked okay. I did:

./ltib -m prep -p u-boot

./ltib -m scbuild -p u-boot

and got the binary:

-rwxr-xr-x 1 lucid lucid 188844 /home/lucid/6sl/ltib/rpm/BUILD/u-boot-2009.08/u-boot.bin


Since I chose the evk mfg spec by default, I correctly see:

+ make HOSTCC=ccache /usr/bin/gcc -B/usr/bin/ CROSS_COMPILE=arm-none-linux-gnueabi- O=/home/lucid/6sl/ltib/rpm/BUILD/u-boot-2009.08 mx6sl_evk_mfg_config

in the build output.


When I tested this on the EVK, I see:

Wrong Image Format for bootm command

ERROR: can't get kernel image!


It looks like the u-boot build does not default to reading from block 2048 of mmc1 which is where the uImage is supposed to be. If I manually do:

mmc dev 1

mmc read ${loadaddr} 0x800 0x16B8

bootm ${loadaddr}             


Then it gets further.

I was wondering if I'm doing something odd or should I not expect it to work with the defaults. It looks like I'll need to modify the u-boot config to change bootcmd to get it to work.
