U-boot parameters reset to default values

nirmalluhana — Wed, 05 Jun 2019 13:33:58 GMT

Hi,

I have used the Boundry device nitrogen6 max board to verify the LVDS LCD panel.

For that, I disabled HDMI port at the u-boot level and added new LCD information in LVDS interface and updated related parameters by using setenv and saveenv. But, after booting/rebooting the board all those parameters are set to default values.

Anyone knows why this thing happens and how I update new LVDS display parameters at the u-boot level?

Best regards,

Nirmal

Hello Bio_TICFSL,

I have already saved the environments using saveenv although it was getting changed at default values while I reboot the board and some parameters didn't update using setenv.

So, is there any other method available to update those parameters?

Best regards,

Nirmal
