Hello
We have developed a custom board for Jetson AGX Xavier, and are having some issues with the module.
we get the system pin and power sequencing as the OEM guide,but now the module have none output .
Key points of debugging phenomenon that : After power on, the current keeps for 20 seconds, then increases to about 1.9A, and then decreases. Like the development board, it is measured that the signal carrier_power_on is pulled up by the module, but there is no interface signal output(include HDMI,USB,PCIE and so on ).
could you tell me the reason or what can i do ?
thanks!
Does same module boot up fine on Xavier devkit?
yes,It can work normally on Xavier devkit
Hi, we have provided Product Design Guide and reference schematic of devkit carrier board. Please follow that to check your design to eliminate the difference. Also there is a checklist sheet in DG which can give guideline with many items one by one, please do check with that first.

and stop here，Can you see what the problem is？
thanks！
It looks like the display is not able to read the edid through i2c. Are you sure the hardware design is correct in this part?
Could you tell me what part of this i2c address corresponds to？
Please check if this log always comes out after you hotplug the hdmi cable first.
sorry,Forgot to say，on my custom board，I didn’t use the same HDMI group as the development board,Xavier devkit used address 15200000 to output hdmi.But in my design，I used 15210000 to output hdmi.The pipe leg on the module 15200000 is suspended.And i changed the DTS. Disable 15200000 and used 15210000 to output hdmi.
What’s wrong with that？
You didn’t suspend it at all. The log still has the old nvdisplay.
