How to build the AzureRTOS ThreadX for iMXRT1170

[t-sen-developer]

Hi, community.

I want to work the AzureRTOS ThreadX (AMP) on iMXRT1170.

I found out the AzureRTOS supported the cortex M7.

Is Cortex M4 core supported AzureRTOS ?

If M4 supported AzureRTOS, please tell me how to build.

iMXRT1170-EVM

[SDK]

MCUXpresso SDK 2.10.1 (MIMXRT1170-EVM.zip)

[IDE]

MCUXpresso IDE v11.4.1 Build 6260

Best regards, 

Takeo.

I create iMXRT1176 ThreadX project using MCUXpressioIDE. But it does not contain azure-rtos->config fold and tx_user.h file. So build fail with error message: "MIMXRT1176_Project_ThreadX_M7\azure-rtos\threadx\ports\cortex_m7\gnu\inc/tx_port.h:78:10: fatal error: tx_user.h: No such file or directory".

Is it MCUXpressoIDE issue? How to fix it?

Hi Rongrong,

I don't remember exactly when I was working on this case as it was several years ago.
I looked in my computer directory and found that the tx_user_sample.h file was stored under.
"<SDK_2_10_1_MIMXRT1170-EVK>\rtos\azure-rtos\threadx\common\inc"

I may have renamed this sample to tx_user.h and used it.
You might try searching for tx_user_sample.h in the SDK directory.

Regards,
Takeo

Hi t-sen-developer:

I use MCUXpressionIDE 11.9.1. I check the IDE ThreadX example and find that azure-rtos/config/tx_user.h. For some reason the new project has no config fold. After I copy config fold to the new project under azure-rtos and reimport this project, then compile successfully.

I wonder why the IDE fail to create config fold in the project. May be it is an issue.

Thanks

Rong

Hi Takeo,

M4 is supported by Azure RTOS, unfortunately, we do not have examples of AMP or M4 implemented in our SDK. We will be collecting feedback to see if this is a scenario we should add in future SDK releases.

Have a great day,

Felipe

Hi, Felipe. 

Thank you for reply. I understand. 

iMXRT1176 has a M7 and M4, so I was considering to use M4 for real time-control, M7 for ML(machine-learning) such as eIQ.

Thanks, 

Takeo
