Not able to detect PCIe endpoint

hello, we are using AM572x GP EVM board for our project, we are testing the PCIe interface between AM572x(configured as endpoint) and one intel sbc board(configured as root complex).

AM572x has PCIe sample code which we are running through CCS and it is running properly as shown in the attached screenshot

intel sbc has Kontron Linux, but when we are giving lspci command it is not able to detect the endpoint, please help us with this.

AM572x:

Intel SBC:

    Jigyansu, 

    I see your EP reported "link is up". So you should be able to also see link is up in the root complex side. can you check the bootlog of the host Linux? I am not familiar with Kontron Linux, but the specific information interested would be about PCIe, where we like to see 1). link is up; 2). any issues probing the EP?

    Hi Jian

    We were able to detect the RC at the endpoint but were not able to detect the EP in RC . We changed the sequence of testing the PCIe .

    Turn on Endpoint 1st then you can turn on the Root Complex as the rescan in RC was not working in the Intel SBC RC.

    Thanks For your Replay
