S32G274-VNP-EVB mdio phy test from u-boot

[yellapu_anishkh]

Hi,

i am using S32G-VNP-EVB board, want to read and write to phy address from u-boot.

In DTS observed pinmux configuration done for MDIO, but there is no entry for phy .

When checked with below commands on u-boot no proper output. Want confirmation, whether this support is there in u-boot.

=> mdio list
eth_eqos:
pfeng_emac_0:
pfeng_emac_1:
pfeng_emac_2:
=> mdio info
=> mii read 0-1 0-6
addr=00 reg=00 data=FFFF
addr=00 reg=01 data=FFFF
addr=00 reg=02 data=FFFF
addr=00 reg=03 data=FFFF
addr=00 reg=04 data=FFFF
addr=00 reg=05 data=FFFF
addr=00 reg=06 data=FFFF

addr=01 reg=00 data=FFFF
addr=01 reg=01 data=FFFF
addr=01 reg=02 data=FFFF
addr=01 reg=03 data=FFFF
addr=01 reg=04 data=FFFF
addr=01 reg=05 data=FFFF
addr=01 reg=06 data=FFFF

Sure, Thank You. I will try from Linux Kernel.

Hello Yellapu,

NXP doesn't have MDIO driver for uboot you will have to jump to the kernel to test it or you can made it.
