Flash instructions:
========
1. Manually upgrade firmware using openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin image.
More details can be found here: https://www.linksys.com/hk/support-article?articleNum=274497
After first boot check actual partition:
- fw_printenv -n boot_part
and install firmware on second partition using command in case of 2:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin kernel
and in case of 1:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin alt_kernel

2. Installation using serial connection from OEM firmware (default login: root, password: admin):
- fw_printenv -n boot_part
In case of 2:
- flash_erase /dev/mtd21 0 0
  nandwrite -p /dev/mtd21 openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin
or in case of 1:
- flash_erase /dev/mtd23 0 0
  nandwrite -p /dev/mtd23 openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin
After first boot install firmware on second partition:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin kernel
or:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin alt_kernel

3. Installation from initramfs image using USB FAT32 formatted drive:
Stop u-boot and run:
- usb start && fatload usb 0:1 $loadaddr openwrt-qualcommax-ipq807x-linksys_mx5300-initramfs-uImage.itb && bootm $loadaddr
Write firmware to the flash from initramfs:
- mtd -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin kernel
and:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx5300-squashfs-factory.bin alt_kernel

4. Back to the OEM firmware:
- mtd -e kernel -n write FW_MX5300_1.1.9.200251_prod.img kernel
and:
- mtd -r -e alt_kernel -n write FW_MX5300_1.1.9.200251_prod.img alt_kernel

5. USB recovery:
- fw_setenv usbimage 'openwrt-qualcommax-ipq807x-linksys_mx5300-initramfs-uImage.itb'
  fw_setenv bootusb 'usb start && fatload usb 0:1 $loadaddr $usbimage && bootm $loadaddr'
  fw_setenv bootcmd 'run bootusb; aq_load_fw && if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'

Notes:
========
IoT device is accesible over spi. Not yet supported.
