I got my shiny new BPI-R3, but I can't get the serial port to work or otherwise get to any CLI/WebUI.
- I've followed the guide
-
dmesg
confirms /dev/ttyUSB0 gets assigned when I plug it in. - I've tried both
screen
andminicom
to /dev/ttyUSB0 @ 115200, 8N1. Screen is blank, minicom reports offline. - I'm pretty sure it's booting to openwrt because if I plug a cable in to the WAN port and listen with
tcpdump
on the other end, I see dhcp requests with Hostname=openwrt. - I can assign it an IP, but
nmap
confirms there are no open ports. - If I try with on of the LAN interfaces, I see the DHCPDISCOVER and see my server's DHCPOFFER, but I never see the DHCPREQUEST.
Does anyone have a BPI-R3 working? Any hints? I think I just need to get the serial port working so I can copy the image from the sdcard to eMMC, but I must be missing a jumper or something.
