BPI-R3: no wifi after brushing

Banana Pi Router design BPI-R3/R3 Mini(MT7986)

After brushing the firmware, after installing luci found no WiFi settings

  • /etc/config/ There is no wireless. Restore factory settings every time you reboot
2

Official openwrt 21.x? Factory reset is known issue.

Please try openwrt 22.x Snapshot

Which uart adapter do you use? Cp2104 (not cp2102) and ft232 working.

NAND mode reboot configuration is not lost, EMMC mode reboot can not save the configuration

  • Compile your own firmware 23.3.3
  • System recovery through the menu
  1. Load production system via TFTP then write to eMMC.
  2. Load recovery system via TFTP then write to eMMC. But I can’t save the configuration after reboot. Here the way to brush is to use mtd erase /dev/mtd10 https://wiki.banana-pi.org/Getting_Started_with_BPI-R3

root@OpenWrt:/# mtd erase /dev/mtd10 Could not open mtd device: /dev/mtd10 Could not open mtd device: /dev/mtd10 You cannot install your own compiled firmware using the following menu 7. Load BL31+U-Boot FIP via TFTP then write to eMMC. 8. Load BL2 preloader via TFTP then write to eMMC.

Flash your openwrt to sd card first. Do not try to install it from bpi version
