bruning ML67Q5003 flash from program
I'm new to the group because I'm working with a 5002/5003 and I need
to program the flash from within the program.
I'm using the Rowley toolset (www.rowley.co.uk).
The code to actually erase/burn flash is assigned to the ".fast"
section which gets automatically loaded to RAM at startup.
Following the Oki docs (500x user manual) and the Rowley-provided
loader.c file, I attempt to erase a sector (2K).
The code does all of the setup commands for a sector erase and then
waits for the beginning of the sector to turn into 0xFFFF. That
never happens. The sector remains unchanged.
I'm only two weeks late on this part of a project -- and I have
the "easy" part.
Here is what the Rowley loader code does and what the Oki docs say:
wait(?forever? or until WatchDog bites)
Any ideas on how to at least erase a sector? If I can erase, I know
I can then program, but I gotta get on first base to do anything.
