hi all.

i use k2h evm and processor SDK 4.3 and i need to configure SRIO in linux.

before i configured SRIO (standalone on DSP cores) but i need configure it in linux.

i read this topic:

but there isnt keystone-k2hk-srio.dtsi file or any related configuration about SRIO in these address: arch/arm/boot/dts

is there any driver or configuration example for SRIO in linux?

Hi,

The correct link to the SRIO documentation in linux kernel is:
software-dl.ti.com/.../Foundational_Components.html

However, it seems to differ from the TI SDK Linux. There are no keystone drivers in drivers/rapidio/devices/ ... Also the dtsi file that includes SRIO is k2hk-uio.dtsi not keystone-k2hk-srio.dtsi as described in the documents.

Let me check this further and I will update.

Best Regards,
Yordan

Hi,

I couldn't find the additional sources described in the tutorial. Try using the SRIO with the UIO driver & dtsi file.
