Problem with enabling infrared (CIR) mode in Linux Kernel of DM814x

Hi Mohammad,

Can you please notice the under construction tag on top of the wiki page?

This driver is not yet included, this will be included in next release.

You can look at this section of release notes to identify what's supported

Hi Anil,

Thanks a lot for your response.The link you mentioned has been last updated on April 11, whereas the link for enabling CIR has been updated on April 17. Does that mean the instruction for enabling CIR is given without being supported? I would appreciate if you clarify this.

Also, I wonder if we can manually create the required driver. As  you know, we need to add two modules for supporting CIR: "lirc_dev" and "lirc_serial.ko." The former can be statically built using the Kernel Configuration tool (menuconfig). I wonder if there is a way to manually create lirc_serial.ko and add it to the kernel. I see the IR driver source code in the drivers forlder of Linux PSP in EZSDK. But, the kernel object file is not created after running "make linux." I wonder if you know how I can modify the makefiles in order to include this folder and create the lirc_serial.ko.

I look forward to receiving your response.

Best Regards,
Mohammad

Greetings,

I checked the new EZSDK which has been released on April first, but I still cannot find the option for enabling CIR in menuconfig. Please let me know how I can access the IR driver, as we really need to chedk IR capability of DM814x.

Thanks,
Mohammad

Hi Mohammad,

If you look at the latest release of EZSDK that is based on PSP_04.04.00.01 release.

Hi Anil,

I''ve tried to load the IR following the instructions. I've been able to create the modules and load them successfully but I'm not seeing any dev/lirc. Can you tell me what steps am I missing?

Thank you.

I also am having an issue with IR/LIRC in 5.04 EZSDK. If its not supported, when will it be? What can we do to get around this? We need it get CIR working ASAP.

Thanks,
