Hi, I'm trying to read the serial number of an LPC4337. Here is my code but I'm not having much luck. I have tried adding 1 to the entry point for Thumb instructions (as below) but that didn't work Does anyone have any idea what could be going wrong? Is there an address I can read directly? Thanks
typedef void (*IAP)(void *, void *); IAP IAP_entry = (IAP)0x10400101; static uint32_t UID_array[4];
// get the 128-bit device serial number // return 4 DWORDs into an array supplied by the caller // static uint32_t IAP_command = 58;
__disable_irq(); IAP_entry(&IAP_command, UID_array); __enable_irq();
