FBK command is not working in imx8mn-evk uuu script

[vinothkumars]

Hi All,

FBK is not working from uuu script. Is there any configuration missing.

Please find my steps,

# get mmc dev number from kernel command line
# Wait for emmc
FBK: ucmd while [ ! -e /dev/mmcblk0 ]; do sleep 1; echo "wait for /dev/mmcblk0 appear"; done;

FBK: ucp .\imx-boot t:/tmp

# clean uboot environment variables
FBK: ucmd dd if=/dev/zero of=/dev/mmcblk0 bs=1k seek=4096 conv=fsync count=8
FBK: ucmd sync

Hi Vinothkumar

one can try to test it on i.MX8MN Nano EVK with uuu sample scripts found in Demo Images

(folder /samples, example_kernel_emmc.uuu)

Thank you @igorpadykov  for the reply,

I tried example_kernel_emmc.uuu script but It's struggled in FBK.

Do I needs to configure anything in u-boot ?

[igorpadykov]

so had you tried on i.MX8MN Nano EVK with uuu sample scripts from Demo Images ?
