BPI-M2U bpi-Bootsel fails


#1

I got a new image of Jessie 8.0 2018-5-24 downloaded to my SD card. the Pi boots up fine but i cant change my resolution.

“bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_1080P.img.gz” gives me a can not write boot error. what can i do to fix this. i need to display in 1080P. at 720P the screen edges are cut off
