Ask the vendor, pretty sure MT7621 wasn't supported by Linux back in 4.14.

Thanks Frolic, thanks a lot for reply,
is there a way to get "sysupgrade.bin" image as now we have uboot and kernel, as of now only building till kernel is happening in openwrt way, how to see to that it is taken ahead for the building of filesystem also... and image as said earlier?? now openwrt is in 23.5.05 can I port the things from given uboot and kernel to this new one if yes how's the way to go about it??

You usually don't need to upgrade U-Boot.

Then you need to add your device to Openwrt 1st.

Do you have a device tree source for your board?

10

Hi no its not but kernel is built that way you know ...

11

hi about device tree source we have something like this arch/mips/boot/dts/Makefile in our code

12

Now you have the source?
Next ask your vendor for instructions.

13

unless you publish "our code", no one but you (and the vendor) knows.
