Other Parts Discussed in Thread: AM62P, SYSCONFIG
Tool/software:
Dear Champs,
My customer is trying to connect Ethernet with 100Mb/s fixed, and modified HW strap of Ethernet PHY(DP83867) in AM62P SK EVM.
But, with this HW strap change, they failed to connect EVM with PC(Windows and Ubuntu) by manually setting of duplex/speed. EVM was connected to PC using cross cable.
They also connected between PORT1 and 2 of EVM using cross cable and tried to test it, but still failed to connect each other.
They modified HW strap of AM62P SK EVM to set "Mode 4" to disable 'auto negotiation' in below, and they removed R374/332 registers and change R373/331 register value to 2.4K ohm by referring below e2e.
RE: SK-AM62P-LP: strap to disable auto-negotiation of Ethernet(forced set to 100Mb/s)
From DP83867 datasheet,
They modified sysconfig as below.
Could you please guide them how they can link-up ethernet of AM62P SK EVM without auto-negotiation?
Thanks and Best Regards,
SI.
