HI All,

How to check kernel dump by using kexec utility on am335x evm .we are using linux-3.14.Kexec-2.0.7.

kexec -d -l /boot/zImage --dts=/boot/am335x-evm.dtb --append="'/proc/cmdline'"

But we got below error.

kexec_load failed: Invalid argument.

Any body did can give me any idea.

Thanks

Hello veera,

You have a typo. The correct argument is --dtb not --dts.

Best regards,
Kemal
