PROCESSOR-SDK-AM335X: UART emulation with PRU_ICSS

Someone

Tool/software:

https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/pru-sw-uart.html
As of Processor SDK Linux v6.1, AM335x supports up to 6 additional UARTs through PRU-ICSS GPIO pins. The UART function is implemented in PRU firmware.
I want to emulate UART with PRUs in my bare metal AM335x project. How can I reach these PRU firmware files?

HI Mehmet,

the subject matter expert for this thread is out of the office this week (U.S. Holiday) and will be back next week so we won't be able to provide an immediate response here. Thanks for your patience.

Regards, Andreas

The PRU firmware based UART is no longer supported in SDK 9.1 (kernel 6.1).
