kirkwood: add support for Seagate BlackArmor NAS220 The Seagate BlackArmor NAS220 is a consumer NAS with two internal drive bays. The stock OS runs RAID 1 over the disks via mdadm. Device specification: - SoC: Marvell 88F6192 800 MHz - RAM: 128 MB - Flash: 32 MB - 2 x internal SATA II drives - Ethernet: 10/100/1000 Mbps (single port, no switch) - WLAN: None - LED: Power, Status, Sata Activity - Key: Power, Reset - Serial: 10 pin header, (115200,8,N,1), 3.3V TTL 9|x - x|10 7|x - x|8 5|x - GND|6 3|x - RX|4 1|TX - x|2 front of case - USB ports: 2 x USB 2.0 Flash instruction: NOTE: this process uses a serial connection. It will upgrade the bootloader and reset the bootloader environment variables TFTP server setup - Setup PC with TFTP server set the PC IP to 10.4.50.5 as TFTP server - Copy these files to TFTP server location - u-boot.kwb - seagate_blackarmor-nas220-initramfs-uImage - seagate_blackarmor-nas220-squashfs-sysupgrade.bin - seagate_blackarmor-nas220-squashfs-factory.bin Seagate NAS setup - Connect LAN cable between PC and seagate device - Connect to serial to seagate device Install u-boot - Boot seagate device and stop in bootloader by pressing any key - run 'printenv' from u-boot and save the values - tftpboot 0x2000000 u-boot.kwb - nand erase.part uboot - nand write 0x2000000 0x0 ${filesize} - reset Update MAC address in u-boot env - Stop in u-boot by pressing any key - Get your MAC address from your saved printenv. Is also on chassis - setenv ethaddr <your MAC> - saveenv Option 1 (recommended) - Install OpenWrt via initramfs and sysupgrade - tftpboot 0x2000000 seagate_blackarmor-nas220-initramfs-uImage - bootm 0x2000000 - *OpenWrt should be running now, however it is not written to flash yet* - From the running instance of OpenWrt use Luci's "flash image" feature from the web site or use sysupgrade from the console to write seagate_blackarmor-nas220-squashfs-sysupgrade.bin to flash Option 2 - Install OpenWrt by flashing factory image from u-boot - nand erase.part ubi - tftpboot 0x2000000 seagate_blackarmor-nas220-squashfs-factory.bin - nand write 0x2000000 ubi ${filesize} - reset Signed-off-by: Kip Porterfield <kip.porterfield@gmail.com>
