I am using “MCIMX6Q-SDB”, its version is C6, bought from DigiKey. So far, I only install SPL and u-boot.img to SD card follow the eewiki.net instructions(below is the website) but it has no message output in serial console.
i.MX6q SABRE Board for Smart Devices - Linux on ARM - eewiki
I wonder something or step is missing, does anyone has the prebuilt u-boot image and related files for C6 board? I'd like to try it. Thanks!
