SNK1M1 board project with azure threadX not working

[ABasi.2]

hello!

i'm trying to make a project with the board SNK1M1 coupled with the NUCLEO-G071RB using azure ThreadX instead of FreeRTOS.

i'm able to replicate the example provided here:

https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Sink#Configure_UCPD_monitor_firmware_responder_for_debug

or the video on youtube:

https://www.youtube.com/watch?v=cbdFHmMOMwk

and all work fine like in the video

BUT

if i change the Rtos with azure ThreadX nothing work anymore!

the code is compiled without problem, it seems to run (no hardfault error) but i can't find the board in the cube monitor UCPD

there is some additional step to use azure threadX instead FreeRTOS?

there is a tutorial of how to use with threadX?

thank you in advance!

Hi @ABasi.2 

I suggest you refer to this example to create a thread and tonsure that all necessary ThreadX components are included. Check memory management generation for UCPD in app_azure_rtos.c. If still having issues, don't hesitate to share your project via Github link.

hello FBL

i see your example, but i think is a gerneric example about threadX, not a specific example about UCPD with threadX

i cheked the memory menagement generationin app_azure_rtos.c and i think its ok

from app_azure_rtos.c and app_azure_rtos_config.h we have

#define USBPD_APP_MEM_POOL_SIZE 6144

static UCHAR usbpd_byte_pool_buffer[USBPD_APP_MEM_POOL_SIZE];
static TX_BYTE_POOL usbpd_app_byte_pool;

tx_byte_pool_create(&usbpd_app_byte_pool, "USBPD App memory pool", usbpd_byte_pool_buffer, USBPD_APP_MEM_POOL_SIZE)

the fact is that i have a perfectly functioning project with FreeRtos, i swap Rtos via Cube MX and noting work anymore

i have also tried of course to make a new fresh project with threadX but same result.. nothing work

ST have a functioning example of  SNK1M1 board  using threadX? like the example provided with freeRtos

thank you

Hello @ABasi.2 

Have a look at all published examples on the USBPD wiki here.

You will see that STM32H5 and STM32U5 have ThreadX USB and power delivery examples.

Nicolas.

Hi @ABasi.2 

Unfortunately, we don't provide direct example for your case!

Did you check USBPD_THREADX symbol to enable in ThreadX support for CubeMonitor API?

Hello Nicolas

thank you for your answer

but the link point to this page, if i click on the link a duplicate of this page is opened

thank you

hello FBL

actually no!

is in cube ide or cube monitor ucpd?

thank you

Hello @ABasi.2 

You are right, link was wrong. I corrected: Wiki.

Direct link to sink application with Threadx here.
