Can not set breakpoint in main()

Hello,

I am getting the following error when I try to run my program.

C28xx: Trouble Setting Breakpoint with the Action "Finish Auto Run" at 0x33b828: (Error -1066 @ 0x33B828) Unable to set requested breakpoint in memory. Verify that the breakpoint address is in writable memory. (Emulation package 5.1.8.0)

Also, when I try to set a break point in main(), I get the following error:

C28xx: Trouble Setting Breakpoint with the Action "Remain Halted" at 0x33b828: (Error -1066 @ 0x33B828) Unable to set requested breakpoint in memory. Verify that the breakpoint address is in writable memory. (Emulation package 5.1.8.0).

I just started moving some time critical functions from FLASH to RAM. Could that be causing the issue?

I am using the following development tools:

1. Docking Station USB-EMU [R3]

2. F28335 PGF Control Card for development

3. CCS 5.3.0.00090

Thanks,

Stephen

The C28x only allows setting 2 hardware breakpoints so if you are setting breakpoints in Flash, you are limited to two at a time. The error may be occuring if you are trying to exceed that limit. CCS may sometimes set some default breakpoints under the hood which is also counted towards this limit. Please check this related post to see where/which settings to check. Hope this helps.

That's what was causing the problem.

Thanks,
