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

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.
-
Why am I getting this error?
-
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.
-
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.
