PCIE card not working and not getting powerON

[afridali123]

hi ,

i m facing issues with USB PCIE card with new jetson orin kit that i dont see issues with agx xavier.

i went through 2 issues in forums

Jetson AGX Orin development kit PCIe power limit

Please share the full log.

PCIe x16 supply not enabled on Development Kit

Hello, I’m trying to use a PCIe card with the AGX Orin Developer Kit. The problem is that the 3.3V and 12V power supplies are not enabled after inserting a card. Only the 3V3AUX supply is active. Now, I was able to enable the power supplies by updating the device tree file tegra234-p3737-fixed-regulator.dtsi as follows: remove the flag “regulator-boot-on” for the nodes p3737_vdd_3v3_pcie and p3737_vdd_12v_pcie p3737_vdd_3v3_pcie: change the gpio pin value to TEGRA234_MAIN_GPIO(H, 4) Is …

i m bit confused how to follow that process to relfash the board.

please provide me detailed steps to reflash i require to flash the image

Is your pcie card connecting on the x16 port of the devkit?

Also, is your board a NV devkit? The patch from the link you posted can only applied to devkit and “specific dekivt”. Not all sku of devkit can work with that.

@kayccc @WayneWWW @Trumany please help to fix this issue, thanks

There is no official solution yet and that patch may not fix your problem either. Will update the solution later.

You can learn how to build kernel first.

Hi,
This is my working version of the device tree file:
tegra234-p3737-fixed-regulator.dtsi (5.7 KB)
It can be found in the source directory hardware\nvidia\platform\t23x\concord\kernel-dts\cvb.
Here is the generated dtb file:
tegra234-p3701-0000-p3737-0000.dtb (300.2 KB)
The file can be copied to /boot/dtb/ on the dev-kit. The configuration file /boot/extlinux/extlinux.conf should be modified to use the dtb file (FDT entry). I think the original dtb file is named differently (kernel_tegra234…dtb). I created a new menu entry so I can switch between different versions by using the debug UART on the micro-USB connector.
