Hi everyone,
I am trying to configure a TZASC (TZC380) in my secure kernel to prevent Linux and some DMA to mess with the secure part of DRAM.
In the documentation, the FAIL ID register holds the identifier of the faulty master. The id n = AID_WIDTH-1 bit long, and represent the master AXI ID.
Where can I find the value of AID_WIDTH and a table listing the possible master AXI ID ?
Best regards,
Vincent
PS: if this is relevant, the target boards are based on iMX6q/iMX7d
Once again, thank you very much for the detailed explanation.
Best,
