u-boot change kernel parameters

uboot.md

I want to change kernel parameters from u-boot.

printenv

Copy the value of mmcargs.

Use setenv to change the value of mmcargs, adding what you need.

In this case I changed the init to bash to have a working terminal without password prompt.

setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} init=/bin/bash

Boot:

run bootcmd
