we bought a new ROCK Pi E HW revision V21. After the latest official rockpie Debian buster image (20200717) booted from uSD card, the eth0 is listed in the OS but not working. Message
eth0: link is not ready is shown in syslog after a manual iface restart via
ip link command (with a cable connected to it). LEDs aren’t blinking.
In case of boot from internal eMMC storage with NO uSD card inserted, both interfaces are working well. Also on previous HW revision of ROCK Pi E (V12), the issue has not appeared.
What can you recommend to get it working?
