Tool/software:
Hi,
We are using 2 different DP83867IRRGZ ethernet PHY for our two ethernet ports, eth0 & eth1. we are devloping on the EVK SK-AM625.
Now, we want to change the GPIO_0 of the PHY of eth1 and we are using the following commands for that. We have also menthioned the commands that we are using to read.
root@am62xx-evm:~# phytool write eth1/0x0/0xD 0x001F
root@am62xx-evm:~# phytool write eth1/0x0/0xE 0x0172
root@am62xx-evm:~# phytool write eth1/0x0/0xD 0x401F
root@am62xx-evm:~# phytool write eth1/0x0/0xE 0x0009
root@am62xx-evm:~# phytool write eth1/0x0/0xD 0x001F
root@am62xx-evm:~# phytool write eth1/0x0/0xE 0x0172
root@am62xx-evm:~# phytool write eth1/0x0/0xD 0x401F
root@am62xx-evm:~# phytool read eth1/0x0/0xE
0x0009
root@am62xx-evm:~# phytool write eth0/0x0/0xD 0x001F
root@am62xx-evm:~# phytool write eth0/0x0/0xE 0x0172
root@am62xx-evm:~# phytool write eth0/0x0/0xD 0x401F
root@am62xx-evm:~# phytool read eth0/0x0/0xE
0x0009
Inspite of doing the above process, when we read, both of the ethernet PHY's register value are changed.
Also, when we check on the board, it only reflects on the eth0 and not on eth1.
Please let us know if we are using the wrong command or what?
