Stuck in recovery mode

hello i build openwrt kernel and sysupgrade for custom dts file. kernel flashed ok to device but stuck in recovery (initramfs) mode whatever tring to flash sysupgrade.How to solve this problem while build openwrt????

I'm not sure if we can help I'd refer to the creator but if that is you well
we kinda know you have to put the device in its recover mode
or upload firmware via TFTP via uboot etc
but you have to have such working firmware to upload

so i'm not sure what you want here ?
if you want help setting up a DTS file you have to start telling us
what the chipset and flash type & partation layup is etc

i already built the firmware 2 files (kernel & sysupgrade). i need your help to flash sysupgrade and remove recovery mode.i try to flash sysupgrade using luci many times and not working for me .i need to know what is the problem? in building process or in other step . thanks for your reply

For anyone to help, you have to provide information

maybe the easiest way is to upload your current project to git
so people have something to look at like project type flash type etc
