Hello,
I wrote a Bootloader to update my TMS320F280025C controller. I want to flash16 bytes at the same time.
The flash process begins and the right data were written to the right addresses in the flash. The problem is that the flash process aborts when the address 0x879DB is flashed.
But only the half data are flashed. When I flash an .bin-File that is smaller than it works fine.
Does anybody no where the problem is and how can I fix them?
Here is the Linker-File for my programm:
