ar71xx: Add support for Netgear WNR2000v1
This patch adds supports for the WNR2000v1 board with 4MB flash, and produces device-specific factory, rootfs, and sysupgrade files for the WNR2000v1. This board is errorneously claimed as supported on the OpenWRT wiki as AP81, but AP81 image would not work because of APT81 image requiring having 8MB of flash, while WNR2000v1 has only 4MB. The image requires the u-boot bootloader to be modified to fuhry's bootloader first. Short specification: - CPU: Atheros AR9132 - 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps - 4 MB of Flash - 32 MB of RAM - UART header (J1) on board - 1x button Factory/Initial flash instructions: - Set up a TFTP server on your local machine. - Download the uImage for ar71xx-generic and the rootfs image for ar71xx-generic-wnr2000 and save in the tftp server root. - Gain serial access to the router via the UART port (telnetenable over the network only won't work!). - Upgrade the u-boot bootloader to fuhry's version by running the script: http://fuhry.com/b/wnr2000/install-repart.sh - When the router restarts, interrupt u-boot and gain access to u-boot command line. - Repartititon the board and flash initial uImage and rootfs as follow. Commands to type in u-boot: # tells u-boot that we have a tftp server on 192.168.1.10 setenv serverip 192.168.1.10 # tells u-boot that the router should take the address 192.168.1.1 setenv ipaddr 192.168.1.1 # erase the region from 0x050000-0x3f0000 erase 0xbf050000 +0x3A0000 # loads sqfs.bin on TFTP server, and put it to memory address 0x81000000 tftpboot 0x81000000 sqfs.bin # it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ # copy bit by bit 0xZZZZZZ bytes from offset 0x050000 cp.b 0x81000000 0xbf050000 0xZZZZZZ # same to the uImage.bin, write it right next to sqfs.bin # again, 0xYYYYYY is the length that tftpboot reports tftpboot 0x81000000 uImage.bin cp.b 0x81000000 0xbf2a0000 0xYYYYYY # We need to tell the kernel what board it is booting into, and where to find the partitions setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd" # Tell u-boot where to find the uImage setenv bootcmd "bootm 0xbf2a0000" # Tell u-boot to save parameters to the u-boot-env partitions saveenv # Reset the board reset Tested on: - WNR2000v1 board. - Initial flash works. Known bugs: - I don't know why factory image doesn't work on initial flash on stock firmware in u-boot recovery mode while it should. - Sysupgrade does not yet work, if you do -f it will mess up your installation (requiring a reinstall of sqfs and uImage).
