Hello

I have a problem when running single wire debug through a J link and an LPC 1313

During debug mode with IAR, my Clock out is exactly 10 Mhz and outside the debug it is the expected 12 Mhz from Internal RC.

Anybody run into this already?

FYI

My problem was that my J-link needed to be set for 'Halt after bootloader'

If the bootloader does not run, it will not load the trim values for the internal RC to give you 12 Mhz
