Hi,
I’m using TFP401 for custom jetson nano board(DVI RX).
By the way, U-boot resolution isn’t correct.
Is there a way to force resolution control in u-boot?
thank you.
Hi,
Actually we don’t enable display during u-boot. Did you enable it by yourself?
When u-boot started, the resolution of the image doesn’t match.
I attached a picture of the problem.
Can i adjust the resolution?
Hi kmlim,
This logo is from cboot instead of uboot.
The information of this image is in bmp.blob under your Linux_for_Tegra/bootloader.
By default, it only supports 3 modes as hardcoded value. Unfortunately there is not yet any tool to update bmp.blob.
You could refer to other forum user’s post for workaround. The keyword is “splash logo”
I checked 3 modes(640x480, 1280x720, 1920x1080).
But, It doesn’t match my LCD resolution.
The log shows that the resolution is fixed at 480p.

Can you support the resolution default with 1280x720?
Or How do I change the default value?
Actually, we don’t support splash logo on DSI panel. Only support HDMI and DP.
