Hi list,
I've built a working RedBoot loader w/ GDB on a V850E/MS1 system with software breakpoints ( "br *" ) and an unused timer output that is fed back into the NMI for periodic "bp hit" checking i.e. much like the existing V850 port, just heavily tweaked for V850E/MS1.
Is there any reason why 'dbtrap' instruction can't be used for breakpoints ?
Now I'm into running the kernel test suite and the question I haven't seen answered is, how do I go about the GDB stuff. I have RedBoot in internal flash and load the application into RAM. Do I keep the GDB code in RedBoot and leave out GDB completely for the application, therefore debugging by using RedBoot's GDB, or should I pack GDB into the app and make it override RedBoot's VSR table, with RedBoot completely out of the picture once I've typed "go"?
If there's more than one way, I'd like the "elegant" route. ;)
Do you have any thoughts against putting GDB stubs into RedBoot ?
