LPC435x Startup

Per LPC435x specification, Cortex-M0 is not accessible through the SWD debug interface. It’s accessible only through the JTAG debug interface.

 

Warning_or

It’s recommended to use the JTAG debug interface when debugging LPC435x, which allows debugging both cores Cortex-M4 and Cortex-M0.

 

When only SWD debug interface is available on the target debug connector, Cortex-M4 can be debugged only. Uncheck the Automatically observe this core option (checked by default) for Cortex-M0 in Hardware / CPU Options / Cores. Without this adjustment, winIDEA becomes unresponsive trying to connect to Cortex-M0 core.
