Flash instruction:
>From Skylab firmware:
1. Associate with SKYLAP_AP
2. In a browser, load: http://10.10.10.254/
3. Username/password: admin/admin
4. In web admin interface: Administration / Upload Firmware, browse to
sysupgrade image, apply, flash will fail with a message:
Not a valid firmware. *** Warning: "/var/tmpFW" has corrupted data!
5. Telnet to 10.10.10.254, drops you into a root shell with no credentials
6. # cd /var
7. # mtd_write -r write tmpFW mtd4
Unlocking mtd4 ...
Writing from tmpFW to mtd4 ... [e]
8. When flash has completed, you will have booted into your firmware.
>From U-boot via TFTP and initramfs:
1. Place openwrt-ramips-mt76x8-skw92a-initramfs-kernel.bin on a TFTP server
2. Connect to serial console at USB3 on EVB
3. Connect ethernet between port 1 (not WAN) and your TFTP server (e.g.
192.168.11.20)
4. Start terminal software (e.g. screen /dev/ttyUSB0 57600) on PC
5. Apply power to EVB
6. Interrupt u-boot with keypress of "1"
7. At u-boot prompts:
Input device IP (10.10.10.123) ==:192.168.11.21
Input server IP (10.10.10.3) ==:192.168.11.20
Input Linux Kernel filename (root_uImage) ==:openwrt-ramips-mt76x8-skw92a-initramfs-kernel.bin
8. Move ethernet to port 0 (WAN) on EVB
9. At new OpenWrt console shell, fetch squashfs-sysupgrade image and flash
with sysupgrade.
>From U-boot via TFTP direct flash:
1. Place openwrt-ramips-mt76x8-skw92a-squashfs-sysupgrade.bin on a TFTP server
2. Connect to serial console at USB3 on EVB (57600 8N1)
3. Connect ethernet between port 1 (not WAN) an your TFTP server (e.g.
192.168.11.20)
4. Start terminal software (e.g. screen /dev/ttyUSB0 57600) on PC
5. Apply power to EVB
6. Interrupt u-boot with keypress of "2"
7. At u-boot prompts:
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) Y
Input device IP (10.10.10.123) ==:192.168.11.21
Input server IP (10.10.10.3) ==:192.168.11.20
Input Linux Kernel filename (root_uImage) ==:openwrt-ramips-mt76x8-skw92a-squashfs-sysupgrade.bin
8. When transfer is complete or as OpenWrt begins booting, move ethernet to
port 0 (WAN).
