NanoPI 4MV2
Hi,
I have a problem with my NanoPi M4V2 (with Raspberry Pi 4 power supply) and the new Armbian release 19.11.3 (Buster). I can boot the image from SD, eMMC. But when I connect any USB storage (USB-Stick or SSD with USB to SATA) then I have packet lost on the Ethernet connection. Any idea where the problem is?
On the interface I can't see problems.
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.xx.36 netmask 255.255.255.0 broadcast
Some further observations of mine in case it helps identifying the problems using ethernet: After noticing that the throughput using the native ethernet connection (eth0) of the M4V2 is low, I checked it using iperf3. I tested the legacy kernel, the current kernel and the dev kernel. The results are quite interesting:
Legacy kernel: Can receive data via TCP from anoter host with high speed (~940MBit/s) but the other way around is quite slow (<1MBit/s).
Current/dev kernel: Ca
