Hi,
I guess this question is rather for developers than for users. I am implementing my own flash programming tool using the ISP protocol. One of the issues I have encountered is that the bootloader in some microcontrollers (eg LPC2129) remaps the first 64 bytes of flash memory, so a read operation doesn't bring actual data from that area.
I would like to know how FlashMagic (or similar tools) deal with this problem? I know that one possible solution is to write and execute a simple program on the microcontroller that remaps the memory before reading it. But is this safe? Are there any other solutions?
Cheers
