Original question:

TMDX654IDKEVM: 10 Mbit/s speed is not supported on PRU ethernet interfaces with SDK 7.0.1

PROCESSOR-SDK-AM65X: support 10Mbps on PRU ethernet interface with TI SDK 7.0.1

Hi Support,

We are using Phytec AM65x SOM and carrier board. The Phytec BSP is based on TI SDK 7.01. 

We have the exact same issue as in this post: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/935344/tmdx654idkevm-10-mbit-s-speed-is-not-supported-on-pru-ethernet-interfaces-with-sdk-7-0-1

In the last reply of the above post, it was suggested that 10Mbps would be supported in 1Q21 using a patch.

I checked the documents of TI SDK. The SDK 7.0.1 says 10M is not supported:

https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/07_00_01_06/exports/docs/linux/Foundational_Components/PRU-ICSSG/Linux_Drivers/PRU_ICSSG_Ethernet.html#features-supported

The latest version TI SDK 8.6 suggests that 10M is supported:

https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/08_06_00_47/exports/docs/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/PRU_ICSSG_Ethernet.html#features-supported

My question is, is there a way to apply a patch or directly get the PRU firmware files of the SDK 8.6 so we can add 10M support on the PRU ethernet interfaces to the Phytec BSP?
