Flash instructions:
========
1. Installation from initramfs image using USB drive:
Put the initramfs image on the USB drive:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_homewrk-initramfs-uImage.itb of=/dev/sdX
Connect serial console (JST PH 6-pin connector):
- 1 - GND, 2 - TX, 4 - RX (115200, 8N1, 3.3V)
Stop u-boot and run:
- usb start && usbboot 44000000 0 && bootm 44000000
Write firmware to the flash from initramfs:
- sysupgrade -n openwrt-qualcommax-ipq807x-linksys_homewrk-squashfs-sysupgrade.bin
or
- ubiformat /dev/mtd22 -y -f openwrt-qualcommax-ipq807x-linksys_homewrk-squashfs-factory.ubi

2. USB recovery:
Put the initramfs image on the USB:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_homewrk-initramfs-uImage.itb of=/dev/sdX
Set u-boot env:
- fw_setenv bootusb 'usb start && usbboot 44000000 0 && bootm 44000000'
- fw_setenv bootcmd 'run bootusb; bootipq'
