SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

Audio player with microSD on STM32F411e-Disco

Posted by simk0024 on 2016-01-23 04:50

Hi all,

I am working on a project using STM32F411e-Disco board and HAL driver. It will read audio files from microSD and then play it through CS43L22 (audio DAC with integrated class D speaker driver).
The connection I used between board and microSD is 1-bit SDIO.

I read a postQuestion about SDIO and CS43L22, it mentioned both of them are IMPOSSIBLE to work together, because SDIO_CK(PC12) and SDIN of CS43L22 are conflict.

I like to change the connection way to SPI connection. However, in this manualQuestion showed that SPI1, SPI2 and SPI3 also conflict with CS43L22.

Did any one of you work on this relevant project before?
How did you design your project and connection to solve this issue?

Please give me some advices.
Thank you very much!
