Hi
Im using a lpc1549 and trying to use the IAP commands (particularly the eeprom read/write). This seems to work at the base 12MHz frequency, until I set the PLL to be 72MHz and set the main system clock to be PLL. It doesn't matter if I use the IAP setPLL function of my own bit twidding function. Then calling an IAP command results in a hardware error
Does this mean I can't use the commands if running at full speed? or is there something I need to do ?
Thanks for your help
Richard
Hello Richard,
I just review the example of periph_iap provided in the LPCOpen, and the main system clock is set to 72MHz since the beginning and the example works fine. I recommend you to use this as a guide for your project to see which configurations you are missing.
Hope it helps!
Have a great day,
Victor.
