Zigbee Traces No Output

[Name]

Hello,
I am trying to get zigbee traces running on STM32WB5MMG running on Sparkfuns development boards.
For my current project I am using this hardware:

• SprakFun MicroMod Main Board - Single - https://www.sparkfun.com/products/20748
• SparkFun MicroMod STM32WB5MMG Processor - https://www.sparkfun.com/products/21438

Standalone UART Connection works fine, only the traces dont work in combination with the Zigbee Stack enabled. To illustrate the problem I created two fresh projects:

STM32WB5MMG_UART_TEST:

• This one is a project for testing the UART on the custom hardware (serial connector located next to the "function zero" connector), I enabled interrupts and dma for rx/tx which works perfectly fine putting out a simple counter.

STM32WB5MMG_ZIGBEE_WITH_TRACES_TEST:

• This one is a fresh project for testing the Zigbee Stack together with traces (based on the same configuration as STM32WB5MMG_UART_TEST). I expect the Zigbee Traces to be received on the serial interface just like the counter in the other project. For this i set up the Zigbee Stack as recommended in the MX UI. Note that I enabled CFG_HW_USART1_DMA_TX_SUPPORT and ensured that in ProjectManager Advanced Settings panel MX_USART_init Not Generate Function call is ticked and Visibility is unticked as hinted in the configuration under CFG_HW_USART1_ENABLED. I do not receive any output.

What I have done: playing around with the settings (a lot!), which was not helpful so far.

For now I am not sure what might be the issue, maybe I am missing a little setting or some configuration, which is hidden somewhere. I appreciate any help!

Kind regards

Hello,

It seems that the IPCC interrupts are note activated on your IOC file making the communication impossible between M0/M4, the stack will then return an error and the traces will not be displayed.

Please activate the IPCC Tx and Rx interrupts as follow

Hello Ouadi,

sorry for the late reply.

I was able to solve to problem.

Apparently the traces do not work on some projects not created from examples, as a function call Init_Debug() needs to be set in function void MX_APPE_Init(void) in file app_entry.c. This solved the problem for me.

Best regards
