flashing new u-boot on the pico-8m

[kapollo]

Hi how to flash the u-boot only with the poky already on the emmc?

Ok I found the way:
bitbake u-boot-edm -c compile -f && bitbake u-boot-edm -c deploy -f && bitbake imx-boot -c build -f
and then
copy the imx-boot-pico-imx8m-sd.bin-flash_evk
from <build_dir>/tmp/deploy/images/pico-imx8m to the target and then
on the device:
dd if=imx-boot-pico-imx8m-sd.bin-flash_evk of=/dev/mmcblk0 conv=notrunc seek=33 bs=1K

reboot
