I have just bought the LPCXpresso55s69 EVK, and so was running some of the examples from the LPCXpresso55s69 SDK (in MCUXpresso), as per the instructions on the page for this board. I managed to get the basic gpio example to build and debug fine without any issues.
Since I am interested in using the sd card and FatFS features of the LPCXpresso55s69 EDK, I then tried running the FatFS example. This then led to the following issue:
"Warning - processor did not halt - gave up waiting
target failed to halt after flash driver reset - (null)
flash start - disabling IRQs failed - rc Ep(08). Cannot access core regs when target running.
chip initialization failed - Ep(08). Cannot access core regs when target running.
failed to initialize flash driver LPC55xx.cfx"
I then tried to continue with the original GPIO example. Unfortunately, now this same issue is appearing with this same example, whereas it was fine earlier.
I read around and it sounds like the board has been put in some mode where the processor can't be stopped. How I do I halt the processor and fix this problem? And is there any reason why it appears to have been caused by the FATFS example?
