Andreas Böhler	28bde50c1d	ath79: add support for KuWFi N650 CPE ... The KuWFi N650 is a 5GHz outdoor wireless bridge based on QCA9563. Specs ===== CPU: QCA9563, 775MHz RAM: 128MiB Flash: 16MiB Wireless: QCA9888 (5GHz only) Ethernet: 2x GBit (via QCA8337), 48V passive PoE Installation ============ From OEM firmware ----------------- The OEM firmware has telnet enabled by default. If not, it can be enabled from the firmware web interface. You need a TFTP server on your computer and the OpenWrt factory image should be available as "n650factory.bin". It is assumed that your computer has the IP 192.168.1.1 and the N650 192.168.1.20 (default IP address). 1. Connect via Telnet to the device and log in with the default credentials "admin:admin" 2. Exploit the limited interface by typing "ps & /bin/sh" 3. Press <ENTER> to start the shell 4. Enter the following commands: $ cd /tmp $ tftp -r n650factory.bin -g 192.168.1.1 $ cat << EOF > /tmp/openwrt.sh IMAGE_NAME="\$1" if [ ! -e \${IMAGE_NAME} ]; then echo "Image file not found: \${IMAGE_NAME}" exit 1 fi . /usr/sbin/common.sh kill_remaining TERM sleep 3 kill_remaining KILL run_ramfs mtd write \${IMAGE_NAME} firmware sleep 2 reboot -f EOF $ chmod +x /tmp/openwrt.sh $ /tmp/openwrt.sh n650factory.bin Once the device reboots, it should load OpenWrt. From UART --------- UART installation is possible since the serial header is already soldered on. The pinout is GND - Tx - Rx - VCC from top to bottom (RJ45 ports are at the bottom). Connect with 115200 8N1. First, boot OpenWrt from TFTP. Enter the following commands in the U-Boot shell, assuming your computer has the IP address 192.168.1.1 and a TFTP server running where the initramfs image is provided as n650.bin: setenv ipaddr 192.168.1.20 setenv serverip 192.168.1.1 tftpboot 0x84000000 n650.bin bootm Once booted, transfer -loader.bin and -sysupgrade.bin images to the device at /tmp. Enter the following commands, replacing the filenames: mtd write /tmp/loader.bin loader sysupgrade /tmp/sysupgrade.bin Reboot and OpenWrt should load from flash. Back to Stock ------------- Back to stock is only possible if you saved a partition backup before installing OpenWrt. Assuming you have fullbackup.bin covering the whole flash, you need to prepare the image as follows: $ dd if=fullbackup.bin of=fwconcat0.bin bs=65536 skip=4 count=212 $ dd if=fullbackup.bin of=loader.bin bs=65536 skip=216 count=1 $ dd if=fullbackup.bin of=fwconcat1.bin bs=65536 skip=217 count=22 $ cat fwconcat0.bin fwconcat1.bin > firmware.bin Transfer firmware.bin and loader.bin to the OpenWrt device. First, flash loader.bin to mtd device loader, then force sysupgrade: $ mtd write loader.bin loader $ sysupgrade -F firmware.bin The reason for the two-step process is the way the flash layout is designed for OpenWrt in contrast to the OEM firmware partition.
