I cannot connect to LPC5534 after program it the first time.
Using
J Link+ Debugger V9.3
MCUXpresso IDE v11.5.1 [Build 7266]
LPC5534
After the first programming I cannot connect to the controller via J-Flash, J-Flash Lite (both 7.62c) or Ozone Debugger 3.28e. The internal bootloader starts the application which is running and available via Modbus Poll.
By trying to download a new program in the µC there is a reset behavior, but the programming is not possible.
Hello @LEGR
How about enter ISP mode, then erase full chip, connect again.
