My ADuC7023 Rev B eval board was working but now I am permanently locked out after down loading a tight forever loop, bad code. The board is ok from a hardware standpoint. The code did not touch the JTAG pins. I think the core is too busy to respond to the JTAG interface. Changed JTAG speed to slow / auto, same error, JTAG mIDAS-Link returns TCK low, RDI-Error 242.
Tried I2CWSD with the reset and download switch sequence for a I2C mass erase and it returned an error also, invalid argument was encountered.
Any suggestions on how fix my board?
