Is this warning important? Warning - bad CRC, using default environment

During bootup of the JetPack 4.6.1 OS on an original Jetson Nano, with a console message log being generated by the host system, (attached to the serial debug port at boot-time), I get the following warning:

Warning - bad CRC, using default environment

The context is:

U-Boot 2020.04-g4335beb (Jun 08 2023 - 21:16:44 -0700)

SoC: tegra210
Model: NVIDIA Jetson Nano Developer Kit
Board: NVIDIA P3450-0000
DRAM:  4 GiB
MMC:   sdhci@700b0000: 1, sdhci@700b0600: 0
Loading Environment from SPI Flash... SF: Detected mx25u3235f with page size 256 Bytes, erase size 4 KiB, total 4 MiB
*** Warning - bad CRC, using default environment

In:    serial
Out:   serial
Err:   serial
Net:   No ethernet found.
Hit any key to stop autoboot:  2  1  0 
switch to partitions #0, OK
mmc1 is current device

As far as I can tell, it doesn’t seem to affect anything and the only reason I saw it was because I was monitoring the serial debug port’s output.

  1. Why am I getting this error?

  2. Is there a way to “correct” the problem it describes?  From past experience I don’t like unknown errors floating around and generally want to know what’s happening.

  3. Should I even care?  Or does this indicate a latent issue that might bite me later in some strange way?

The entire boot-up log is attached.
