[This is a resend, slight e-mail problems today, it seems]
I'm trying to build my application as a ROMRAM application,
but it crashes. These are my steps:
- build w/CYG_HAL_STARTUP = ROMRAM
- write the .bin image to flash 0x1000000
- when the application is run, it enters an infinite loop,
as register r12 on the line below from hal_platform_setup.h
contains 0x1000000.
mov pc,r12 // Change address space, break
pipeline
Do I need to modify *romram.ldi/h? If so, I confess ignorance
as to the required changes. I would have expected to find a "rom" memory
entry as there is in *rom.ldi.
There probably isn't much required to get this up and running, because
others have done it:
