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
dmesgconfirms /dev/ttyUSB0 gets assigned when I plug it in.
- I've tried both
minicomto /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
tcpdumpon the other end, I see dhcp requests with Hostname=openwrt.
- I can assign it an IP, but
nmapconfirms 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.
