Please check the date on the board by typing "date"

also

the syntax for date is date 081916012019

So, type date in your terminal followed by 08 which will stand for Month then 19 which will stand for the present Date of that month then 16 which stands for Time (24-Hour format), 01 for Mins finally 2019 which stands for Year.

k sir, can you share steps to boot board with sd card

Polimera Gopalkrishn

Jan 20, 2020

make two partictions 1.boot 2.rootfs

copy all images in boot partition except rootfs & copy the rootfs in rootfs partition . follow the below steps

step1: get the prebuilt images from Ashraful and directly copy into boot partition by using cp command (cp boot.bin /media/gopal/boot)

Note: boot partition should be bootable.

step2: for flashing rootfs follow below command

sudo tar -xvf rootfs-name -C /media/gopal/rootfs
