I'm getting started with the NXP Yocto stuff. I've followed the tutorials and built "core-image-base" and other recipes.
In the tmp/deploy/images/imx6ulevk/ directory of my Yocto repo, there are u-boot files/links like so:
I'm not exactly sure which recipe these files came from, but I assume the .img is a bootable binary. This is the output for "file" info:
$ file u-boot-sd-v2017.11+gitAUTOINC+ca0c3f3fac-r0.img
u-boot-sd-v2017.11+gitAUTOINC+ca0c3f3fac-r0.img: u-boot legacy uImage, U-Boot 2017.11+fslc+gca0c3f3 for\270, Firmware/ARM, Firmware Image (Not compressed), 344176 bytes, Tue Mar 13 14:19:51 2018, Load Address: 0x87800000, Entry Point: 0x00000000, Header CRC: 0x0F9794F0, Data CRC: 0x01F24B80
Therefore I tried this command to write u-boot to an SD:
sudo dd if=u-boot-sd-v2017.11+gitAUTOINC+ca0c3f3fac-r0.img of=/dev/mmcblk0 seek=2 bs=512
But after powering up the EVK with the SD, I see nothing happening on the serial terminal...as if it's never running u-boot.
Can I use the .img file to boot my EVK? If so, how? It's unclear if I got something wrong with the "dd" command, or am trying to use the wrong file.
