[Openocd-development] [PATCH] fix broken dap component base for tms570 on debug logic

[Mathias K. <ke...@fr...>]

Hello,


this patch fix the broken dap component base from the debug logic/processor on the tms570 cpu.

There are some more components but i dont know if they are all wrong or only this one. I have append
the dap info output.

There is also a new CoreSight component with id 0x930. This is still missing in the
"dap_info_command" function.

Anyway, i was able to connect to the cortex-r4 (tms570) with a cortex_a8 configuration. I can read
the registers, halt, step and resume seems to work.


Regards,

Mathias
