背景:orin nx, sdk6.2.1, Ubuntu22.04, 自研底板
这里要把GPIO09配置为什AUD_MCLK用,要怎么配置?
*** Please note that this reply is generated by LLM automatically ***
Based on the provided context, it appears that you are asking about the Jetson Orin NX module, specifically the SDK version, operating system, and GPIO configuration.
Here’s a breakdown of the information:
- Jetson Orin NX: This is a module from NVIDIA’s Jetson series, which is a family of embedded computing boards designed for AI, computer vision, and robotics applications.
- SDK version: The SDK version mentioned is “sdk621”. This likely refers to the JetPack SDK, which is a software development kit provided by NVIDIA for developing applications on Jetson modules. The version number “621” might indicate a specific release or update of the SDK.
- Ubuntu 22.04: This is the operating system running on the Jetson Orin NX module. Ubuntu is a popular Linux distribution, and version 22.04 is a specific release of the operating system.
- GPIO09AUDMCLK image: This appears to be a specific configuration or image related to the GPIO (General Purpose Input/Output) pins on the Jetson Orin NX module. GPIO09AUDMCLK might refer to a specific pin or signal on the module.
- 690283: This number might be a build number, revision number, or some other identifier related to the image or configuration.
- 266 KB: This is likely the size of the image or configuration file.
In comparison to other Jetson modules, the Orin NX is a more recent release, and its SDK and operating system versions might be different from those of older modules. For example, the Jetson Xavier NX and Jetson AGX Xavier modules might have different SDK versions and operating system releases.
To provide a more comprehensive answer, I would need more information about the specific requirements or questions you have regarding the Jetson Orin NX module. However, based on the provided context, it appears that you are working with a specific configuration or image on the Jetson Orin NX module, and you might be looking for information on how to develop applications or configure the module using the provided SDK and operating system.
*** Please give the thumbs up if you get answers you like. Or provide feedback to help us improve the answer. ***
Hi jeremyzhang,
What’s your use case for this pin?
Are you trying to configure it for Audio Clock?
Have you tried to configure it through pinmux spreadsheet?
做Audio Clock用,
把GPIO09配置为AUD_MCLK,es8389挂在i2s2上
参照:Jetson_Orin_NX_and_Orin_Nano_series_Pinmux_Config_Template.xlsm
| 211 | GPIO09 | GPIO09 (AUD_MCLK) | 50k | pd | GPIO3_PAC.06 | Input | Int PU | Initiator | Disable | GPIO #9 or Audio Codec Master Clock |

Have you referred to Audio Setup and Development — NVIDIA Jetson Linux Developer Guide for the Audio porting?
You have to configure it as AUD_MCLK in Column-AT.
Please also share the full dmesg and device tree for further check.

Your driver has been probed correctly and the pinmux/clock configurations look good to me.
You cannot measure the clock signal because the system is in idle state. The clk_summary shows an enable count of 0, meaning the clock is turned off by the power management system when no audio is playing.
The clock only outputs when an audio stream is active.
Please run the following command to start a stream:
$ speaker-test -D hw:1,0 -c 2 -r 44100 -F S16_LE -t pink
While this command is running, please measure GPIO09 with your oscilloscope. You should see the ~11.28 MHz signal.
The current logs show the amplifier is currently “Off.” Please use amixer to unmute the outputs:
$ amixer -c 1 set 'Left Output' on
$ amixer -c 1 set 'Right Output' on
$ amixer -c 1 set 'Master' 100%
