Prerequisites
1) TFTP server
2) 3.3V USB to TTL cable for UART console
2.54mm pitch 4-pin header for UART is readily provided on board, no modifications are necessary to access it
TTL connector pinout: 2=TX, 3=RX, 4=GND
Arrow marks pin 1 which is 3.3V
Serial port settings: 115200 8N1 no flow control
The device will most likely ship with a QSDK-based firmware.
1. Power on device and interrupt u-boot to obtain u-boot CLI
2. set serverip to IP address of the TFTP server, for example:
`setenv serverip 192.168.1.10`
3. Download image from TFTP server:
`tftpboot 0x44000000 openwrt-ipq807x-generic-compex_wpq873-squashfs-factory.ubi`
4. Flash ubi image to both partitions and reset:
`sf probe
imxtract 0x44000000 ubi
nand device 0
nand erase 0x0 0x3400000
nand erase 0x3c00000 0x3400000
nand write $fileaddr 0x0 $filesize
nand write $fileaddr 0x3c00000 $filesize
reset`
Afterwards, you can use sysupgrade to flash new OpenWRT images.
