Flashing old image with kernel 3.8 on new board

We got new BeagleBone Black cards, and when try to flash image I got an error,
Error: [/dev/mmcblk1] does not exist.

I sure, it possible.
The question how?

Your new BBB contains a newer model of eMMC, this model is not support
on the 3.8.x kernel till 3.8.13-bone80 was released with these 2
patches:

https://github.com/RobertCNelson/bb-kernel/commit/bd5a1f38c99bbe712d21c1e145b0c660dca9dee7

Your options for the 3.8.x kernel are as follows:

1: Upgrade to 3.8.13-bone80
2: apply both patches and rebuild your kernel

For 2 see:

Regards,

Thank you.
I try this way. Kernel rebuild takes a time

Yes, it’s work.
Thank you.
