Part Number: AM625
#1. Boot AM62x-SK E2 with 2 ethernet port connected to network.
#2. ifconfig and Ping PC to ensure ethernet port and network connected.
#3. Print CPSW_MDIO_ALIVE_REG and CPSW_MDIO_LINK_REG registers value, in PSDK8.3 they are always 0, but in PSDK8.4, 8.5 and 8.6 relevant bit are set.
Log as below. seems something wrong with MIDO status in PSDK8.3. What is changed in later version SDK, and what issue resolved?
