HI,
I would use the Jetson PCIe lines to connect an SSD M.2 key, 4 lines to it.
Someone can give me the interconnection list between Jetson connector and M2 PCIe connector(on the evaluation board there is the PCIe schematics for key E with one line only)
Please, is it necessary some SW preset to boot time in order to instruct the processor to accept the SSD?

thank you in advance

Hi,

Have you checked the OEM design guide of TX2?

The connection is listed in the reference schematic.

Hi,

Please refer to “USB Lane Mapping” in adaptation guide. You need to use “ODMDATA=0x90000 for Configuration #1” to enable M.2 Key E.

Thanks,
