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();
