In case anyone comes across this in the future;
We were able to disable the JTAG and use GPIO0 by first compiling a new busybox which includes the 'devmem' function, then using busybox devmem we were able to change the Memory at address 0x1804006C from 0x00000020 to 0x00000022 (set bit 1 to 1).
./busybox devmem 0x1804006C 32 0x00000022
After doing this, GPIO0 can then be manipulated using the traditional methods.Statistics: Posted by jstep — 10 Jan 2019, 17:03
