Part Number: AM6442
Other Parts Discussed in Thread: TMDS64EVM
Hi experts,
Q1:Is it correct that AM6442 and Linux SDK can support 10Mbps ethernet communication?(Both CPSW and IICSSG)
Reference URL: Processor SDK AM64X Software Developer's Guide - 3.6.3.3. Features supported
Q2:Also, has the following thread issue been resolved in the latest SDK v8.6?
Reference thread:e2e.ti.com/.../am6412-phy-does-not-work-with-10mbs-on-sdk-08-04-01-04
The result of ethtool command with SDKv8.6 on TMDS64EVM is as follows.
