Hi We created a custom carrier board based on the dev-kit carrier board (all IO is be the same, no special stuff of any kind). After flashing it with SDK manager (1.9.3.10904) with jetpack 5.1 (rev1), we lost the PCIe connection. ‘lspci’ shows no rootcomplex of any kind. There is a FPGA connecte…

[image] Ayrton_Leyssens: The PEX_L5_CLKREQ_N signal is connected to GND on our board while on the nVidia carrier, it isn’t. The pin should be left unconnected if not used. Please share PCIe part schematic, otherwise it is hard to debug if any schematic issue.

Also, I remember that you asked similar question before.

Did you remember to apply this patch to your board?
