Hi,
I have a custom board for a custom ASIC. The ASIC has R5 and M0+ cores.
I have wired VCC, GND, RESET, TMS, TCK, TDI and TDO from the board to the J-Link's 20 pin header.
When I give connect, I get the option to choose the CPU core which was selected as Cortex-R5. But the debugger is unable to connect to the target.
Commander log is given below:
