Re: Accessing Memory
I use KickStart and write code in assembly. With only a few
exceptions, the assembler works fine. For those few exceptions, I had
to write the code in hex instead of mnemonics.
The linker works for me too but I had to write a linker command file
I use the debugger to download to FLASH. That works too.
I also tried to use BSL to download. The only problem is, if I am not
careful, I can easily erase the calibration constants in Info-A. My
solution is, I copied Info-A and kept that in a file in my PC.
I use BSLDEMO2 in the PC. When I turn on the -x option, it handles
Flash above 0x10000 fine.
