Hi experts,
I have the same issue as the original thread. I want to perform 10Base-T communication via PRU-ICSS in an environment running LinuxOS.
The hardware uses TMDSIDK572 and the software uses ”SDK-LINUX-AM57X 06_03_00_106”.
I thought I changed the EtherPHY registers directly from "mdio-tool", but it doesn't seem to work.
Q1:Are there any settings missing to enable 10Base-T functionality? Any advice you can think of would be helpful.
[Detail]
I used "mdio-tool" to dump eth0 and eth2 register information.
I used "mdio-tool" to write to the following registers on eth2.
Address0x00: Writing 0x01140 resulted in reading 0x1100.
Address0x04: Writing 0x01f1 resulted in reading 0x0111.
I used "ethtool" to check the information before and after changing the register of eth2, but there is no change. (10Base-T is not supported.)
