AM5728: PCIe pinmux issue

Rogerio Almeida

Part Number: AM5728

From customer:

The spec. says that, for PCIe, there can be one with two lanes or two with one lane, but the pin-mux tool only allows one. Is there a newer pin-mux tool that allows two?

Hi Rogerio,

Just to clarify before going further, you mean you don't have the use case options for PCIe_SS1/PCIe_SS2 for single/dual lane correct? We can add this. You can still configure the needed pads though, they are currently available no problem.

Thanks,

Alex

Alex, that was my understanding from customer email...Thanks for adding it to pin mux.

Sorry f the misunderstanding, let me clarify. The tool will only allow me to have 1 PCIe bus, not two as stated in the spec. Thanks, Ron.

Rogerio, Ron,

Alright, I have filed internal ticket for this to be fixed. Note that team is wrapping up a new release already as we are speaking, so these updates will probably make it into the version after.

Thanks,

Alex
