TDA4VM: PCIe communication under QNX

Cherry Zhou

Mastermind 22235 points

Part Number: TDA4VM
Other Parts Discussed in Thread: DRA821

Hi team,

A customer intends to do PCIe communication between the TDA4VM chip and another chip under a QNX system based on a linux system, and the customer would like to know if there is a sample code on the QNX side.

Could you help check this case? Thanks!

Best Regards,

Cherry

Hi Cherry,

PCIe communication from TDA4VM to TDA4VM is supported. To enablie this functionality a PCIe driver from QNX is required.

Please contact QNX Software Systems for further information on availability of the PCIe driver.

Does the same answer goes for DRA821 PCIe with QNX? (contact QNX etc ...)
