Hi Guys,

I try to call the IAP-routines from ARM-mode with help of the code 
to enter THUMB-mode from the file section:

static void callIAP(void)
{
  // fast way to get the address of flashParams[] directly into r0
  register void *pFP asm("r0") = flashParams;

  asm volatile(" mov r1, r0\n"          // copy &flashParams[] into 
r1
               " bx  %[iapLocation]"    // 'bx' because IAP is Thumb 
mode
               :
               : "r" (pFP), [iapLocation] "r" (IAP_LOCATION)
               : "r1" );
}

The code runs fine, the IAP is entered in thumb mode and returns to 
ARM-mode again. Only nothing happens: when I try to read the Part Id 
(command 0x36) it returns 0. The same for the Boot Code (command 
0x37). R0 / R1 points to the (same) FlashParams. With help of the 
debugger I see the 0x36/0x37-commands in these parameters are 
overwritten by zero.

Who can help me please?

Thanks in advance,

Conrado
