TMS570LC4357: ESM Group 3 - Aborts generated or not?

Hi Magnus,

Magnus Aronsson said:

Do all Group3 errors generate aborts?

Yes, all ESM group 3 errors will generate aborts directly to the CPU.

The difference between ESM group 2 error handling and ESM3 error handling is below

The ESM group 2 channels are error high severity. When any group 2 error occurs, the ESM module will then generate an interrupt request to the VIM module. Finally the VIM module will generate a FIQ interrupt request to the CPU. In esmHighInterrupt handler user will find out what leads to the ESM error and handle it per his/her application.

The ESM group 3 (high severity) channels have no interrupt response as they are reserved for CPU based diagnostics that generate aborts directly to the CPU.
