program 3 copies of code in memory and verification by checksum

Other Parts Discussed in Thread: MSP430F5438

Hello.

I would like to program 3 copies my code in the memory of my MSP430F5438. I saw that there are 4 banks. So, I would like to program these 3 copies in bank B, C and D.

Bank A will contain a start up program who will verify the other banks with a checksum and load the program stored in this other bank if the checksum is correct.

But, how can I program the 4 banks separatly? And what's the command to load a specific bank ?

I use Code Composer Studio V4.

I'm a beginer with MSP430 and I have a lot of difficulties to realize this function.

Thank you in advance.

Yur problem is almos tidentical to the use of an application -based BSL (Bootstrap loader).

You should search the forum for threads about 'own BSL'. This has been discussed widely in the past, including one or two recent and active threads.

You can actually store your custom BSL directly in the BSL memory, that way you have all four banks of main flash available for your application.]

See slaa450a "Creating a Custom Flash-Based Bootstrap Loader (BSL)", and this link in the TI processors wiki
