AM623: PRUSS example in processor SDK?

Anthony 

No specific plans to add more PRU examples in MCU+ SDK ywt. We have basic enablement and may port a few things from AM64 based on customer needs but we are not really looking to expand the scope of M4 MCU+ SDK in terms of PRU. 

On A53 Linux, goal is to provide basic foundational ability for customers to do more with PRU - similar to AM335x but no plan to offer any custom protocols etc. As and when we have community boards, the traction may change. 

We may do some helper examples  outside of SDK , let us know if you have any specific things your customers are requesting and we can see how we can support

Hello A,

Everything Mukul has stated so far is correct - at this point in time, we support initializing and loading the PRU cores from the Linux A53 cores on AM62x, but not from the M4F core on AM62x.

Adding some additional information:

For your new PRU customers, make sure they see the new "PRU Getting Started Labs". My hope is that these labs help to create the very basic foundation that customers can build on: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_05_00_21/exports/docs/common/PRU-ICSS/PRU-Getting-Started-Labs.html

For examples of working with GPIOs, I will point you to the PRU Software Support Package (PSSP):

simple GPIO example (does not include pinmuxing): https://git.ti.com/cgit/pru-software-support-package/pru-software-support-package/tree/examples/am335x/PRU_gpioToggle

More complex GPIO example (CCS & beaglebone black specific pinmuxing), check out the AM335x Hands-on Labs: 
https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_05_00_21/exports/docs/common/PRU-ICSS/PRU-Hands-on-Labs.html

Hope this helps,
