Hi,

I am using AM572x with TI RTOS.

My question is can i use Pin Pong memory concept to read data by arm and write by PRU from external memory.

Thanks,

Hi,

Yes, this is inter-processor communication. The PRU writes data and needs to notify ARM to pick it up. Please see this topic: processors.wiki.ti.com/.../IPC_Users_Guide
