Hello.

I am new in IAP and have one question. I know that access and execution in sector0 is impossible during write or erase operations in sector 1 or 2. It means that my write/erase routines should be executed in RAM. May I execute another part of my bootloader in sector 0?

For example, such way:

1) RS232 routine(reception of code) -- execution in sector 0

2) flash write routine -- execution in RAM

3) RS232 routine(reception of next code) -- execution in sector 0

4) flash write routine -- execution in RAM

and so on

My micro is ST7MC.

Tnx in advance

Hello.

I have an experience with ICC protocol and ST7F321. I transfer the program that is execute in RAM via ICC pin. With this solution you can reprogram all sector. In the ST7F321, there are lot of ram so I suppose that the RS232 routine can be execute but in the ST7MC I don't know.

how many RAM in this uC?

bye.

excuse for my basic english. ;)

Hello.

Tnx for answer. But I am interested in IAP only. I have to flash my micro during industrial work. Micro has 768 bytes RAM.
