On the STM32MP157C-DK2, can I use/interface the available muRata 1Dx with M4 only (& not A7)?

On the STM32MP157C-DK2, can I use/interface the available muRata 1Dx with core-M4 only (& not core-A7)? I am not quite sure if the wifi module 1dx (U8 on the kit) is controlled by A7 or M4?

Anyways, I want to interface it with M4. So, can it be possible?

Hello @ANalg.1​ ,

The software framework needed to make the murata 1DX works is only available under linux (A7Core).

As specified on the wiki related to WLAN: https://wiki.st.com/stm32mpu/wiki/WLAN_and_Bluetooth_hardware_component#Software_frameworks

 

Regarding the hardware assignment of the peripheral and its DT configuration, you can see in the following link, that the brcm node is defined in the node sdmmc2:

https://wiki.st.com/stm32mpu/wiki/WLAN_device_tree_configuration#DT_configuration_-28board_level-29

It is explained in the Peripherals overview page that sdmmc2 is CortexA7 only:

https://wiki.st.com/stm32mpu/wiki/STM32MP15_peripherals_overview#Internal_peripherals_overview

 

So you can't use the module muRata 1Dx with core-M4 only.

Hope it helps,

Regards,

Kevin
