Hi,

Please let us know, PCIe is driver is supported in uboot. Also how to test the PCIe device is initialized without any issue in uboot.

Does the existing u-boot binary supports PCIe. or is there any sample board configuration in which PCI is enabled and initialized.

Thank you,

PCIe driver is supported in U-Boot.

U-Boot log will contain a line corresponding to each enabled PCIe controller.

This line will indicate the link training status. Trained link corresponds to properly enumerated EP device.

> Does the existing u-boot binary supports PCIe.

Yes, the LX2160A firmware contains U-Boot supporting PCIe.

Specific PCIe protocol support details are determined by the RCW being used - not U-Boot itself.

A PCIe controller can be used as source and/or destination of the qDMA - refer to the QorIQ LX2160A Reference Manual, Chapter 24 qDMA.

The RM is confidential and can be provided if NDA between NXP and your company is present.
