Cannot find uEnv.txt BeagleBone Black board

Hi all!
I have try to building new kernel for my beaglebone black board.
After finishing booting OS with new kernel for my board, I have try to find uEnv.txt file on my board. But I cannot find it.
So anyone here know this issue?
Please help me for solving this!
My uboot version is WIP/22Nov2019 and my kernel is 4.14.108-ti-r124
Hope to see your feedback!

@AnhPT26,

It’s stored on the first partition of the mmc, usually in the /boot/ directory. If you plug in a serial adapter, u-boot will show you a better idea of where it loaded it from.

Hi @RobertCNelson!
I checked when booting board.
I got one warning is:
Loading Environment from FAT… *** Warning - bad CRC, using default environment
I don’t know what is this mean?
Please help me!

Regards!

@AnhPT26,

Loading Environment from FAT… *** Warning - bad CRC, using default environment

U-Boot has the ability to store it’s environment on the FAT partition. We don’t use this by default in the our images. It’s just saying it “tried” to load something, but the CRC failed so it ignored it. AKA, nothing was actually stored, and it was blank…
