BBB can not find uEnv.txt

I am using the URL page to install Linux for BBB on my SD card.
https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black

In Step “Copy Root File System”, then
Next Step says " Set uname_r in /boot/uEnv.txt"
I could not find uEnv.txt in /boot folder. Am I missing any step downloading ubuntu?

That’s fine, the file does not normally exist in a fresh install. Thus just add the content to the file as stated.

Regards,

Hi @RobertCNelson!
I have started follow these link for building kernel for my beaglebone board.
After finishing for booting new OS, I cannot find the uEnv.txt file.
So, could you help me about the issue?
