We tried it now with
fuse prog 0 5 0x0000C86D
but it does not boot either. As we can workaround this by shortcutting a resistor on the board, we did not want to blow the 0x10 fuse as well, as this fuse will brick the board (and the workaround) completely.
My question is: Is the fuse:
fuse prog 0 6 0x00000010
necessary to boot from the fuse settings or is it just a security setting? Currently, my only hope is, that this single fuse is necessary to "activate" the fuse settings from 0 5. If not, the settings we used for the second board (0x0000C86D) will not work either.
Can you help me out? Should I execute fuse prog 0 6 0x00000010 as well and risk bricking the second board fully?
