Hey everyone,
A newbie here. I am trying something very basic. We have a Qualcomm board with the below QSDK (vendor stock):
"kernel": "4.4.60", "description": "OpenWrt Chaos Calmer 15.05.1" version
We are trying to upgrade to a different Linux and OpenWrt version. We have compiled the image from openWiFi repository with below outputs:
openwrt-ipq807x-cybertan_eww622_a1-squashfs-sysupgrade.tar
openwrt-ipq807x-cybertan_eww622_a1-squashfs-nand-factory.bin
When we did the sysupgrade via GUI, the board was stuck on uboot and won't move further.
When we asked Qualcomm support regarding upgrade they said:
You can upgrade the platform from Linux-4.4 based release image to Linux-5.4 based release with single image. i.e., nand-ipq807x-single.img or norplusnand-ipq807x-single.img You cannot upgrade kernel alone with uboot unchanged.
What exactly does this above statement mean?
How can we update the uboot?
Do we have to boot the factory image on the router? (factory.bin file)
Anything will be helpful to understand how to boot this firmware on the board.
Regards,
