write_program_memory
PostPosted: Wed Mar 09, 2005 10:59 am     Reply with quote
I am having problems with the write_program_memory function used on an 18F2620. CCSC PIC C 3.219.

We have written our own bootloader which is much the same as the example provided with the compiler. However, it seems that the write_program_memory function calls another internal function (FLASH_WR or something like that) which is not in a constant memory location. When loading a new program, the upload works great until FLASH_WR is overwritten, then write_program_memory stops working. Any thoughts? (nb: same with RS232 getc( ) function, but this one is simple to inline).

If this is the case does anyone have a C/asm implementation of write_program_memory?

Many thanks.
