I dd'd FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img to a microsd card and booted it (no eMMC or USB storage attached). This created .185 instead of the .149 for networking: --- 192.168.1.185 ping statistics --- 102 packets transmitted, 102 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 0.126/0.198/1.925/0.244 ms --- 192.168.1.120 ping statistics --- 102 packets transmitted, 102 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 0.175/0.206/0.629/0.044 ms (.120 is a ThreadRipper 1950X.) Consistent with the past, it appears that various Rock64 v2.0's may not be equivalent. At least for my context, FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img of itself does not seem to be a problem for the Rock64 v2.0 that I have access to. That spans U-Boot and FreeBSD being the same as you tried. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)home | help
