Entered MASROM device mode problem at RK3288

I erased “EraseFlash” function at the “Upgrade Firmware” menu and then my firefly RK3288 is entered “MASKROM” mode and it said “found one MASKROM device”. I can’t upload my firmware in this mode. When I tried to upgrade, it said “download boot start. download boot fail”.

Please let me know how to set normal boot load mode.
Thanks

Only upgrade Loader image , rk3288 will be in loader mode .And try upgrade your firmware again.

Thanks. I’ll try it.
