    Hi,

    To inject error into ring accelerator please follow the below steps.

    • Define a 4KB region of space in DDR and place CRING in this region
    • After initialization of the descriptor, firewall 4 KB region of DDR in which CRING was placed
    • Submit ring descriptor to channel.     
    • Monitor NAVSS_RINGACC_0_error_log register.

    Please find the patch below on implementation. And the same could be built by building udma_memcpy example.

    ra_test

    Example Build: 

    Location : pdk/packages/ti/build

    Command : make udma_memcpy_testapp_freertos BOARD=j784s4_evm CORE=mcu2_0

    Regards,

    Manojna
