MSP430F1132: External flash uploading

Part Number: MSP430F1132

Hello,

In my design there is a hardwired flash to MSP430F1132. It functions as a ROM for screens and fonts for LCD.

The problem is how to upload data to the Flash. My idea is to download small program to MSP RAM as a small add-on to BSL which receives the data and programs the flash. Programming needs one time at the assembling time only.

My questions are:

I have seen small assembly example programs which even needs already 250 byte, so it seems very challenging to write the serial com, flash program, puffer, stack in a 256 byte RAM; is there a chance to write it?

Is it possible to use part, routines of the BSL ROM?

Any better idea - if there are - to program the flash?

    Hey Laszlo, 

    I don't think there is any way to use the BSL ROM, it is used to program the MSP430 itself, not program external flash.  

    I'm also not sure if you'll be able to fit it or not.  Maybe someone from the community with experience trying to write this will be able to give a sense of size, but I don't know.  

    Thanks,

    JD
