TheCompiler got a reaction from KatiePier in flash corruption on msp430f5510
I'm not sure why one would be needed - the crystal on the schematic is just needed for USB, for the system clocks I want to use the DCO/FLL.
I have posted the same in the TI e2e forums, and there it was pointed out I forgot to increment VCORE. With the default (0), the maximum allowed frequency was 8 MHz, so it's mind-blowing it actually did run that well at all
This solved the issue.
