DRA821U: QNX PCI HW Module

Part Number: DRA821U
Other Parts Discussed in Thread: DRA821

Hi,

I am trying to get PCI drivers working for QNX (SDK 08_04_00_04), but am having trouble getting the pci server running.

According to the PCI Server user's guide, I need to define "PCI_HW_MODULE" which should be a 'pci_hw-*' file in ${QNX_TARGET}/processor/lib/dll/pci/ on my development host.

I can see these files for x86_64 targets, but there is nothing in the folder for a aarch64 target like tha DRA821.

Does TI have this file, or some way to enumerate PCI devices on the DRA821?

Thanks for any help!

Michael.

Hi Michael,

Recommend reaching out to the QNX/Blackberry team for support on this. The QNX PCIe framework, it is a QNX/Blackberry deliverable.

Regards,

Kip

Hi Kip,

I reached out to QNX and they said they do not officially support PCI on aarch64 architectures. Do you know if this is something TI is looking to implement into the SDK, or will we need to write our own PCI drivers?

Cheers,

Michael.

Hi Michael,

QNX/Blackberry do support the PCIe Framework on certain devices of the TI Jacinto 7 Family of devices (aarch64 architectures) and can be contacted for further information.
