Jetson Linux 35.3.1 PCIe slot 12V turn on

[t.adam1888]

Hello,
I have a problem with PCIe slot 12V on Jetson AGX Xavier Devkit. After the boot the 12V is turn off. I changed the dtb files and recompile it but it wasnt solved the problem. I use Jetson Linux 35.3.1. Could anyone tell me the solution? Or Could anyone give a link about an example for turn on PCIe slot 12V?

(I used the dmesg command and I always got PCIe slot regulator error: -517)

Best Regards,
Adam
