Is it possible to upload ones program to the flash memory of a LPC2132
through the JTag interface?
I'm using a Chameleon POD JTag Interface and OCDRemote, in combination
with Eclipse.

I know that it is possible through Keil micro Vision, but as I'm using
C++, this is not an option.

Is it completly undoable or does a workaround exist?

Søren

Hi Soren,

I'm using a 2294 and program flash via JTAG.  I make use of the tool 
chain's ability to open files on the PC via the debugger/JTAG 
connection, i.e., using "semi-hosting".  

The basic approach is to write a (C/C++) program that performs the 
following steps (error checking, etc omitted):
  - open a file on the host
  - read data from the debugger/host file into a buffer
  - as needed, erase a flash sector using IAP call
  - write the buffer to the correct offset within the current sector 
using IAP call
  - repeat until end of file or end of flash space

The program descibed above is loaded into RAM with the debugger and 
executed.  On program completion, the part's flash is programmed.  

Regards,


Tom

Søren,
I have a C++ program and can flash via JTAG using IAR debugger and 
JLink (I think JLink is made by Segger but IAR sells it too).

James,
  I use the IAR debuugger with JLINK interface...  I did not know 
that you could FLASH a chip via JTAG.

Can you describe (in detail) this operation?  Are there any tricks to 
it, that may not be intuitive to a novice user like myself?

Thanks,
 - Mike

Mike,
I assume you are using the IAR compiler.  The main challenge is 
getting the linker set up to place the program into flash (not 
RAM).  We use a linker script file (not the dialogs).  You should 
have some examples from IAR.  IAR support can help you with set-up.

Hi Tom

Is this the kind of program that is found under the Files
(LPC-Flashroutines...) or do you have another program that can do the
trick.
And will it work with a Raven JTag (Chameleon POD) and GDB?
