Question

Which environment variables do you need to configure on uboot?

Answer 1

In uboot, some commonly used environment variables include bootcmd, bootargs, and ethaddr.

Step-by-step explanation:

In uboot, there are several environment variables that can be configured. Some of the most commonly used environment variables include:

• bootcmd: This variable specifies the command to be executed when the system boots up.
• bootargs: This variable contains the command-line arguments passed to the kernel.
• ethaddr: This variable sets the MAC address of the ethernet interface.

These variables can be configured using the setenv command in uboot. For example, to set the bootcmd variable, you can use the command setenv bootcmd 'run myboot'.
