I have a X96 air P1 TV box，I burn Armbian_20.10_Arm-64_focal_current_5.9.0_desktop.img to SD card and rename u-boot-s905x2-s922 to u-boot.ext it boot successful (use meson-sm1-sei610.dtb)，when I was run /root/install-aml.sh write the systemOS to emmc it also can boot successful，but the wifi and hdmi audio don't work，so i search from google and download a new u-boot file name with u-boot-new，I copy the u-boot-new file to SD card and rename it to u-boot.ext then insert the sd card to tv box, the wifi and hdmi audio work great, I'm very excited, but when I run /root/install-aml.sh again, the tv box boot failed , it endless echo "missing envitonment variable: bootfile" and "retrieving file: prelinux.cfg/xxx" in boot process, finally it say "DMA reset timeout" and "Config file not found " , I guess this is boot script bug, how can I setting the env var or how to fix this error ? forgive my poor English, thanks！
