CCSv4: Executing GEL code, while CPU still running

Karthik Ramana Sankar

Hi all,

In CCSv4 I was trying to invoke some user-defined GEL functions (which involved memory read), while the CPU is still running. These GEL functions do not work (get stalled), if the CPU is running. In CCSv4, the GEL functions work only when the CPU is halted.

However, in case of CCS v3.3 I was able to invoke GEL functions at run-time. I am using CCSv4 (version: 4.0.0.16001) and I like to whether this feature of invoking GEL functions at run-time is supported in any of the latest versions of CCSv4.

Thanks,

Karthik.

Hi Karthik.

See this thread:

http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/31082/109041.aspx

Basically the default behavior in v4 changed so that it does not allow intrusive debugger actions while the target is running. GEL calls like memory read are intrusive. See Eddie's post at the bottom of the thread to change this behavior to how it was like in v3.

Thanks

Hi Ki-Soo Lee,

Thanks for directing me to the relevant thread. Now able to call GEL functions, while CPU is running (whenever debug access is done, the CPU is halted momentarily).

In the thread mentioned above, it was discussed that real-time debug support will be provided for certain targets in CCSv4.2. Now, as CCSv4.2 is out, I would like to know whether real-time debug is supported for the latest family of WBI communication infrastructure DSP processors.

Thanks,

Karthik.

All their devices should support real-time mode.
