TDA4VM: How to config RINGACC ERROR interrupt?

LI WEIPENG

Part Number: TDA4VM

Hi experts

I want to config the RA ERROR interrupt , but I don't konw how to map the RA error event to UDMASS_INTR_AGGR0, and how to map the event from UDMASS_INTR_AGGR0 to NAVSS_INTR_ROUTER0. Do you have any example for it ?

Looking foward for your reply.

I am using FREERTOS(SDK8.2) + QNX. I want to moniter the RA error when I am executing UDMA transmission.

Hi Weipeng,

Is the UDMA transaction being done on an R5 or A72? Trying to understand if this is a QNX based question or a Free RTOS based question, along with where the interrupt is to be handled R5 or A72.

Thanks,

Hi KB

Thanks for your reply. The UDMA transaction is done on the R5.

Hi Weipeng,

Since, this is a event specific to RING IP, not specific to individual ring it has not been made part of udma_event.h and so no examples available in PDK.

You can use sciclient_rmIrqSet API to register the event. Check Ring global error event in https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721e/interrupt_cfg.html
