In AM62A BSP env variables are stored uEnv.txt file which resides in the fat partition of boot media.
During boot, the environment variables defined in the U-Boot source are used by default. Additional variables which are present in the uEnv.txt file can be manually imported to U-Boot environment using “run envboot” command.
The import process is automated during U-Boot to kernel transition, not during the initial U-Boot, boot stage. Therefore, the variables saved in the uEnv.txt file are not printed on default.
Any further changes made to the U-Boot environment can be saved back to the uEnv.txt file by executing the “run save_env” command.
