i need help to run the CPU-Board without the IO-Board. As far as i understand the situation this does simply not work because the Jumpers on the IO-Board are not present the the CPU-Board goes into serial Bootloader-Mode.
So my solution would be to set the efuses in a way that the board does always boot into emmc except the jumpers are set so that the serial bootloader could be used.
I already broke one board by setting the wrong fuses and i would like some help an the matter.
So far i found out that the the documentation on the fuses can be found here: IMX7DRM but i have trouble understanding it correctly.
I also know that i can burn the fuses in u-boot with the command "fuse prog".
Can someone tell me which fuse i would have to burn and how the excat command would look like?
Thank you very much!
