Troubleshooting

Hangs to jump application from bootloader

Copy erase.act file to the LPC55S69 drive to erase flash memory.

I got "APPLICATION_ADDR undeclared" errors

The application configuration files contain relative paths to the bootloader files. You need copy config file to the application root.
