Hi,
The problem is that your configuration is for plain processor but not based on board.
for example,
BOARD_BootClockFROHF48M() can be generated for configuration "LPCXpresso54680", but not for "LPC54608J512 "
According to developer "The pre-set configurations are available and tailored only for boards, if you would use a processor that does not have any board available, you would need to add functions and configure clocks manually in clocks tool."
you can switch configuration in "MANAGE" tab.

Have a great day,
Jennie Zhang
