LPC435x Startup

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



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.
