Disabling use of hardware single stepping on at91rm9200

Development Boards MicroMod

Hello,

I have a problem single stepping using an AT91RM9200 when in thumb mode. Since nobody could help me so far I used gdb to debug openocd. I found out that when I set “has_single_step” to 0 single stepping seems to work. Therefore, I have two questions:

  • - What net effects does it have to disable the use of hardware single stepping on an AT91RM9200?

  • - What would be the best way to disable it? Patch the source? Or is there a configuration option?
