Can I rewrite the data in boot bank by the program from the nonboot bank?

Hi All

I work with RIDE IDE v.746 with paths P1, P2 and evaluation board STR910.

I have got the problem with the write to the boot bank.

For example, my program starts from bank 1(boot bank). I can write the data to the bank 0 without problems. FMI works very well. But a part of my program is in the bank 0. This part of program should write some data to the bank 1(nonboot bank). I tried very many methods (change the bank, attributes,rewrite the startup, rewrite the linker script files, divide the program into two programs) , but no effects. I can't write the data or code to the boot bank from non boot bank.

What is wrong?

I was looking for in the datasheet and errata sheet but is nothing there.

Regards

check that every interrupts are disabled

run every code for write to flash only from RAM

Hi

I tried your idea. I placed the code for the write to the boot bank into RAM. But this method doesn't work. I can try to place complete program into RAM (boot from RAM). But this method isn't suitable for my project.

Thanks you and best regards
