Linux/TDA2: Linux/TDA2 to Jetson TX2 PCIe communication

Sreerag A G

Part Number: TDA2

Tool/software: Linux

Hi,

I have been doing for communicating Jetson TX2 and Ti TDA2X via PICe in Linux platform. I tried to workout configuring TDA2X as end point and Jetson TX2 and Host.

Both have configured properly but during enumeration pci device is not detected at host side. Is there any option to configure TDA2x as generic end point device in linux?

Hi Yordan,
I have gone through the same configurations mentioned in the link. I got TDA2X as end point device. But that device is not detected in the Jetson. I am communicating between Jetson and TDA2x.

Hi,

Is there any option to try the PCI test between two TDA2X boards in RTOS platform?

Hi,

We have a simple driver to configure in RC and EP mode present in PDK.
Please refer to pdk\packages\ti\csl\example\pcie\write_loopback for more information.
The issue pertaining to PCIe communication between Jetson TX2 and TDA2 seems to be resolved. Please create a new thread if you have any further questions.
