mmcpart=2
optargs=fixrtc video=HDMI-A-1:e capemgr.enable_partno=BB-BONELT-HDMI
#importent change the line above
uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if
mmc$
loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}
loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}
and it worked thanks
