How to communicate between SPE and Linux kernel?

How to integrated work SPE-fw and CUDA?

hi jachen, I couldnt find tegra186-aon.dtsi file. If update tegra186-aon.dtsi. I will re-flash full device again? By the way, I add this code for init ivc in main. #if defined(ENABLE_IVC_CCPLEX) ivc_echo_task_init(&ivc_echo_task_id); #endif I add target_specific.mk ENABLE_IVC_CCPLEX

My device is Jetson AGX Xavier.

I updated the file tegra194-aon.dtsi as below:

                  ivc_aon_shub@d880 {
                            reg = <0xd880>, <0x1d880>;
                            reg-names = "rx", "tx";
                            nvidia,frame-count = <32>;
                            nvidia,frame-size = <256>;
                    };
	};
};

aon_echo {
	compatible = "nvidia,tegra186-aon-ivc-echo";
	mboxes = <&aon 0>;
	status = "okay";
};

aondbg {
	compatible = "nvidia,tegra186-aondbg";
	mboxes = <&aon 1>;
	status = "okay";
};

I put the scripts in the devicetree-ivc.md above aon_echo.

I compiled the kernel source and flashed the board, but the /sys/devices/aon_echo/data_channel didn’t appear.

Is there any steps necessary that I missed? Or is there any steps wrong?

Should I modify the SPE source file and flash?

Currently, what I want is making the communication between Kernel and SPE works.

Thanks!

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi Will99,

It seems you posted at wrong form, that’s why your issue is out of our radar.
We now move it into Jetson AGX Xavier forum.
May I know if this is still an issue to support?
