Verdin AM62: Support for RT-Linux OS

Technical Support
1

Hi Team,

We would like to know whether the Verdin AM62 supports RT-Linux. If yes, please share the required configurations to be enabled in kernel apart from the generic guide provide here -Real-Time Linux | Toradex Developer Center.

It would be great, if you can share an example, where a device driver(consider SPI based device driver) uses real time capabilities of RT Linux.

T&R,
Akshay

Hi, I’m the Toradex AI Assistant. The Toradex Support team will follow up with you shortly!

Did you like my answer?

:+1: :-1:

Based on the provided context, there is no specific mention of the Verdin AM62 supporting RT-Linux. The context does mention that Toradex provides a real-time kernel recipe for i.MX6 & i.MX7 based modules and some information about real-time capabilities and the PREEMPT_RT patch in general. However, there is no explicit information about the Verdin AM62’s support for RT-Linux or specific configurations for it.

For detailed information and specific configurations, you might need to refer to the Toradex Developer Center or contact Toradex support directly for guidance on using RT-Linux with the Verdin AM62.

Please, also check if these links can help you solve your problem:

Hi @HMUser,

Toradex prebuilt image with PREEMPT_RT Patch can be found here
(available for AM62 as well).

You can enable CONFIG_PREEMPT/CONFIG_PREEMPT_RT=y in kernel as mentioned here

We do not have examples of SPI.
Can you check this

Hi @sahil.tx ,

Thanks for your reply,
Can you please share any driver example for RT linux? We are planning to run the kernel driver with RT Linux capabilities

T&R,

Hi @HMUser,
Unfortunately, we dont have any demo/examples at the moment.

Hi @sahil.tx ,

Thanks for letting us know.
Would like to know, whether Can we apply the RT capabilities to linux platform driver level(Kernel Space)? or Is RT capabilities are just applicable only to applications running in user space?

Hi @HMUser,
I request you to go through the documentation to get clear idea
