RTFM is a TLA and means "Read the Manual" (I forgot what the F stands
for).
In general this is the kind of answer you may see if questions are asked
that are being answered that can be found in the manual or application
notes.
Anyway, I was wrong about the app.note - it's in the user manual of the
LPC2106 (IAP commands on page 193) - I did not have this one handy while
entering my mail (yes, there are still PCs that do not have Acrobat Reader
installed ...)

There is a Philips app.note on this, explains how to do this from both ARM
and Thumb. Furthermore, ARM/Thumb interworking is also explained in the
ARM7 TDMIS manual on the ARM website.
In general, calling Thumb code from ARM is easy. Just make sure you
specify the ARM/Thumb interworking flag for your C-compiler

thank u Rob,
i found the application note.. by the way what do u mean by RTFM..?
i haven't found any RTFM in the application note.

Thank u Rob,
i am aware of the thumb and arm inter-networking.
i found the link for the ISP.
can u pls send the link of the app note from philips that sumraize
the ARM and thumb modes for IAP programming.?
thanks,

hello all,
This is abt Flash Programming,,is onchip flash programming BY USING
IAP, possible in ARM mode.?
i found a flash programming example by using IAP in THUMB Mode in the
group
here it is ...
**********************************************************************
static void callIAP(void) __attribute((naked));
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" );
}
But as IAP is alaways called by a word pointer in register R0
(pointing to RAM),so is this not possble in ARM MOde Right..?
If so then,how can i make changes so that this piece of code works
for ARM mode..?
Am I right or missing something..?Pls suggest
regards
dp
