TMS320F28377D: grouping of CPU1 and CPU2 during debug - attempt #3

In summary, we are having problems suspending and resuming execution in CCS when the two CPU's are grouped. The grouping works given some rules as to the sequence in which the CPU's are reset; this recipe unfortunately only works when using the XDS100 of our EVM's. When the XDS510USB is the interface, the grouping of CPU's generates the following error:

Is this issue related to gel files, or other initialization parameters of the debugger? Any thoughts?

Thank you!

    Hi Lenio,

    We are looking into this. As you know XDS510 is third part emulator (you are using BH or SD?) we may need to check with them on this.

    XDS510 emulator had issues with grouping option hence it's recommended to use XDS200 or XDS100 emulator for the same.

    Also when grouping CPU1 and CPU2, user need to reset CPU1 only or reset CPU1 and CPU2 separately but not group reset because that would not work. On CPU1 reset, CPU2 also gets reset and at same time if CCS also tries to reset the CPU2 (which group reset will do) and release it from reset, it'll give error.
