TMS570LS3137: What to do Error Trapping (including Peripheral Slave Error Trapping) - L2/L3 Interconnect ?

Hello Arriy,

This type of error will normally result in a device exception - data abort or prefetch abort dependent on the type of access that triggered the abort. As far as how this is handled in the abort handlers, it is up to the application but it is also dependent on the source of the abort. Many times, the only way this can be determined is through inspection of the CPU registers and it isn't possible on the device level. The only recourse may be to put the device into a safe state or perform a reset to start fresh. Before taking the drastic rout of a reset, it may be beneficial to perform the software test of function on the logic to insure there wasn't a fault in the detection logic as well.
