ramips: add support for Skylab SKW92A in EVB Specifically, SKW92A_E16, described here: http://www.skylabmodule.com/wp-content/uploads/SkyLab_SKW92A_V1.04_datasheet.pdf Specification: - MediaTek MT7628N/N (580 Mhz) - 64 MB of RAM - 16 MB of FLASH - 2T2R 2.4 GHz - 5x 10/100 Mbps Ethernet - 2x u.FL - Power by micro-USB connector at USB1 on EVB - UART via micro-USB connector at USB3 on EVB (57600 8n1) - 5x Ethernet LEDs - 1x WLAN LEDs - 1x WPS LED connected by jumper wire from I2S_CK on J20 to WPS_LED pin hole next to daughter board on EVB - WPS/Reset button (S2 on EVB) - RESET button (S1 on EVB) is *not* connected to RST hole next to daughter board 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). Signed-off-by: Russell Senior <russell@personaltelco.net>
