How Do I Run My Firmware After Flashing? (LPCXpresso845MAX Board)

kk7xo — Sun, 25 Aug 2019 01:09:59 GMT

I have firmware debugged and running from the debugger in the MCUXpresso IDE (ver. 11.0). I can use the IDE flash tool to flash the LPC845 with no errors. However, if I try to run the firmware without the debugger, it never starts up. I have tried powering the board with JP1 installed or not installed and it makes no difference.

How do I run my firmware stand-alone from flash without a debugger?

Thank you. Got it working. I just needed to compile it in release mode and change the library from semihosting to nohost.
