DP83867IR: default register setting with RGMII

Hirotaka Matsumoto

Part Number: DP83867IR
Other Parts Discussed in Thread: TIDA-00203, TIDA-00204

Hi all

Would you mind if we ask DP83867IR?
Do you have default register setting with RGMII as reference data?
Or, if it possible and you have .c source code of TIDA-00203(EMI/EMC Compliant Industrial Temp Dual Port Gigabit Ethernet PHY Reference Design) which is relation to DP83867IR with RGMII, could you give us?
(Or, TIDA-00203 includes "drivers/net/phy/dp83767.c"?)

Kind regards,

Hi Hirotaka-san,

Page 47 in the datasheet show the bootstrap to use for setting RGMII without the need for register access (driver).
Pin RX_D6 has an internal pull-down so it should go into RGMII operation without the need for an external pull-down.

The other option is to set RGMII using register 0x32 Bit[7].

Also, do you mean to ask about TIDA-00204?

git.kernel.org/.../dp83867.c

The 867 driver link above also has RGMII enabling call.

Kind regards,
Ross
