Other Parts Discussed in Thread: DP83869, TMDS64EVM
Tool/software:
Hello TI,
We are using EVM AM64x where we see eth2 with phy DP83869 is failing,
We downloaded the code for AM64x from TI git "git clone git.ti.com/.../oe-layersetup.git tisdk", we compiled with steps provided by 1.2. Building the SDK with Yocto — Processor SDK AM64X Documentation. With this binary we are seeing eth2 is not coming up under "ifconfig -a".
