Network issue in quick star
- OS: Ubuntu 22 LTS
- image: openwifi img
If can't ssh to the board via Ethernet for the 1st time, you might need to delete /etc/network/interfaces.new on SD card (on your computer).
If still can't ssh the board via Ethernet, you should use UART console (/dev/ttyUSBx, /dev/ttyCH341USBx, etc.) to monitor what happened during booting.
EXT4 fs error rootfs issue
Sometimes, the 1st booting after flashing SD card might encounter "EXT4-fs error (device mmcblk0p2): ..." error on neptunesdr, changing SD card flashing tool might solve this issue. Some tool candidates:
- gnome-disks
- Startup Disk Creator
- win32diskimager
antsdr e200 UART console
If can't see the UART console in Linux (/dev/ttyUSB0 or /dev/ttyCH341USB0), according to https://github.com/juliagoda/CH341SER, you might need to do sudo apt remove brltty
Client can not get IP
If the client can not get IP from the openwifi AP, just re-run "service isc-dhcp-server restart" on board and do re-connect from the client.
