Hi
We are developing Jetpack 5.0 BSP on our Xavier custom board. Our question is:
Failed to output HDMI display during UEFI.
Success to output HDMI display during kernel boot.
After tracing source code , UEFI is failed to discover T194GraphicsOutputDxe driver in function GetFirstWinForThisHead.
Here’s the debugging trace log in UEFI:
Head index=0 DC_DISP_SYNC_WIDTH = 0x00000000
Head index=0 DC_DISP_BACK_PORCH = 0x00000000
Head index=0 DC_DISP_FRONT_PORCH = 0x00000000
Head index=0 DC_DISP_DISP_ACTIVE = 0x00000000 = 0 x 0
GetFirstWinForThisHead: Head index 0 Window index=0 Disabled
GetFirstWinForThisHead: Head index 0 Window index=1 Disabled
GetFirstWinForThisHead: Head index 0 Window index=2 Disabled
GetFirstWinForThisHead: Head index 0 Window index=3 Disabled
GetFirstWinForThisHead: Head index 0 Window index=4 Disabled
GetFirstWinForThisHead: Head index 0 Window index=5 Disabled
It looks it get zero from display controller registers at any offset, e.g. DC_DISP_SYNC_WIDTH, DC_DISP_BACK_PORCH, …
Could you guide my any further info to debug this ? Thanks.
Are you sure your change in kernel dtb also applied to UEFI dtb?
yes, I do the following steps to apply kernel dtb to UEFI dtb (all steps on done in driver package)
Update kernel dtb to kernel/dtb
Remove bootloader/<kernel dtb> in case flash.sh didn’t update my updated kernel dtb
Put machine into recovery mode
Run command to flash UEFI dtb only.sudo ./flash.sh -r -k bootloader-dtb <model> mmcblk0p1
Check updated dtb is applied in UEFI by checking model name.
Please share full log from serial console.
Hi @WayneWWW
Please see attached UEFI boot log.

Looks like bootloader cannot find correct device tree node. You better doing full flash.
Hi @WayneWWW nvdisp-init stage. We manage the HDMI reset pin by tca9539 but tca9539 driver was not compiled into nvdisp-init.bin out from release. After changing cboot source, UEFI on HDMI works now.
Here’s the successful UEFI on HDMI log:
