Hi
You have to check if there is working Yamon. You can do this with serial cable. If Yamon is working - there is relative easy solution of the problem.
if Yamon is broken (zboot (1) failed) - There are two possible options:
- Removing NOR flash and programing content with external flash programmer, and re-soldering it again on the PCB.
- using JTAG for flashing broken NOR flash
check this:
