Specifications:
SoC: AR7130
DRAM: 32Mb DDR1
Flash: 8Mb SPI-NOR
LAN: 4x 10/100Mbps via ADM6996 switch on MII
WAN: 1x 10/100Mbps via RMII
PCI: 2x mini-PCI
UART: standard QCA UART header
JTAG: yes
Button: 1x WPS, 1x reset
LEDs: 8x LEDs
Installation instructions:
The original FIS partitioning does not provide enough
space for the kernel, so the installation must start
with re-partitioning the flash from RedBoot.
The suggested partition table is the following:
RedBoot 0xBF000000 0xBF000000 0x00040000 0x00000000
kernel 0xBF040000 0x80060000 0x001F0000 0x80060000
rootfs 0xBF230000 0x00000000 0x005B0000 0x00000000
FIS directory 0xBF7E0000 0xBF7E0000 0x0000F000 0x00000000
RedBoot config 0xBF7EF000 0xBF7EF000 0x00001000 0x00000000
Which can be created with:
fis init
fis create -r 0x80060000 -e 0x80060000 -b 0xbf040000 -l 0x220000 kernel
fis create -b 0xbf260000 -l 0x580000 rootfs
The kernel and the rootfs must then be loaded from TFTP:
load -r -v -b 0x80060000 openwrt-ath79-generic-atheros_pb42-squashfs-kernel.bin
fis create kernel
load -r -v -b 0x80100000 openwrt-ath79-generic-atheros_pb42-squashfs-rootfs.bin
fis create rootfs
Once OpenWrt is installed, the normal sysupgrade method will work for
upgrades.
The MAC address is stored in the "boardconfig" partition, which is
automatically created.
