I want to change the u-boot variable in the linux userspace instead of the u-boot prompt window before starting kernel.
I am using lsdk1906 and my kernel is 4.19. I am booting from SD card.
I heard there is a way to do that by downloading the u-boot-tools
After I run "apt-get install u-boot-tools"
then I perform fw_printenv in the linux it tells me that
Cannot parse config file '/etc/fw_env.config': No such file or directory
I checked this link:
Accessing U-Boot environment variables from Linux - ArmadeusWiki
I need to know
# MTD device name Device offset Env. size Flash sector size Number of sectors
I do not know what is the value of the location of my uboot.
Can anyone help?
