TMS320C6678: MPU forbidden read

Part Number: TMS320C6678

Hello,

I am trying to generate an interrupt when performing a read access into L2 memory area were read are prohibited (trough MPU configuration).

But it does't work.

Could you confirm me that the event corresponding to a read access violation in L2 memory is the 124 : L2 DSP memory protection fault ?

Because when I perform a read at adress 0x00874000 no event is generated.

I precise that I have configured MPU register as follow:

- L2MPPA29 is set to 0x0000518, i.e this allow only write and execute access for AID0 and local to the memory area 0x00874000--0x00877FFF

Thanks by advance.

Regards,
