out/target/product/rk3576_firefly_aio_3576c/rk3576_firefly_aio_3576c-ota-eng.xxx.zip Generate the base material package path
out/target/product/rk3576_firefly_aio_3576c/obj/PACKAGING/target_files_intermediates/rk3576_firefly_aio_3576c-target_files-eng.xxx.zipCopy the base material package and rename it, mainly for subcontracting upgrades.
cp out/target/product/rk3576_firefly_aio_3576c/obj/PACKAGING/target_files_intermediates/rk3576_firefly_aio_3576c-target_files-eng.xxx.zip ~/ota/v1.zip Package compiled firmware and upgrades
./FFTools/mkupdate/mkupdate.sh -l rk3576_firefly_aio_3576c-userdebugIn the rockdev/Image-rk3576_firefly_aio_3576c/ directory, find the corresponding firmware and burn it to the machine, then the machine can carry out the full package upgrade and the difference package upgrade,put 'update.zip' into /sdcard/ and restart the full package as prompted.

The v1.zip basic material package has been made, and another v2.zip material package needs to be made to generate the difference package. You need to modify the kernel DTS code or Android code, and then run the command again.
./FFTools/make.sh -d rk3576-firefly-aio-3576c -j8 -l rk3576_firefly_aio_3576c-userdebug -oRegenerate a new base material package that we can copy.
cp out/target/product/rk3576_firefly_aio_3576c/obj/PACKAGING/target_files_intermediates/rk3576_firefly_aio_3576c-target_files-eng.xxx.zip ~/ota/v2.zipGenerate the incremental OTA package command
