TMS320F2800157: Compare Error Forcing test

AHashem

Tool/software:

Hello,

I am implementing Compare Error Forcing Test, The issue I face is after I set MG_LCM_REGS.LCM_CONTROL.bit.CMP1_ERR_FORCE = 1; the NMI not fires, as per the following paragraph since LCM_STATUS.CMP1_ERR_FORCE_DONE as the following screen shot from the debugger, the NMI should fire.

Note:

- I enable the global interrupt before the execution of the test.

- I know that this test should be run when the debugger is not connected, so I disconnect the debugger durcing the test and the test fails because the NMI is not fires

This should already be enabled by default . Are you seeing this bit cleared ?

I am assuming you are writing to this register via your code and not via CCS register view. Can you check if LSCMPERR bit in NMIFLG register is getting set when you force the error ? I did this test and I was able to see this flag getting set.
