what i meant was any modification you made to official code?

if not, check if your power source or try with another bone, the info was not enough to determine exact cause.

Thanx for your quick reply .

I’ve not made any change in official code. Bcoz this is first time I’m compiling

linux on Beaglebone.

When I tried with Angstorm Linux downloaded from Internet, It is working fine.

But Now I compiled Linux kernel and generated rootfs using Buildroot.

I’m getting error which I sent in earlier post.

Do I need to give some more details.

What should be in uEnv.txt file

Waiting for reply

Dear Yiling Cao

When I executed following command on uboot prompt

U-boot#bootm

I’m getting following error
Verifying Checksum … Bad Data CRC
ERROR: can’t get kernel image!

What could be the problem ?
