Hi ALL

Technical Reference Manual 　section 5.1.1.5.12 and 5.1.1.5.13

There is setting B010104Ch of CTRLMMR_PCI_DEVICE_IDx Register, but what are these contents to mean?

Our developed board , VENDOR ID 104Ch DEVICE ID B010h is readable at the time of PCIe BOOT setting.

Is this correct?

Best Regards.

Yes, this is correct. Keep in mind that the PCI_ID changes depending on the function of the device (RC vs EP).

Thank you DK

The data sheet has the following description

8.4.2.17 Peripheral Component Interconnect Express (PCIe)
ThePCIe subsystem
Dual mode root port (RP) or end point (EP) modes. Selectable through bootstrap pins.

How do you switch between RP and EP with bootstrap pin?

I would like you to teach me a specific method

I believe that this is an error in the datasheet. I'm checking with Design team now.

Hello,

I have confirmed that this is an error in the datasheet. There is no BOOTMODE pin to latch RC vs EP mode. I've filed a bug against the document; it should be fixed in the next revision.
