Re: [SOLVED] Problem with I2S+DMA on Nucleo H743ZI2 with WM8731 Audio Codec

PS i am still not sure why disabling the D-Cache is necessary in STM32Duino and not necessary when running the same code from STM32CubeIDE. i have a hunch that it might be hidden somewhere in the linker script or the compiler options but as of now this is a bit beyond me … maybe someone else wants t...

One question: what is the actual address of the buffer you are trying to use for DMA? If it starts with 0x2xxxxxxx - i.e. it's in DTCM - it won't work on the H7. https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devices (I have not confronted this exact issue with I2S; but I did ...

thank you for your reply but i have already wrapped all functions generated by STM32CubeIDE in a

Code: Select all

extern "C"
en bloc in my example above ( sorry for the messy source code again ).

[SOLVED] Problem with I2S+DMA on Nucleo H743ZI2 with WM8731 Audio Codec

hej, i am currently trying to get the WM8731 working on the Nucleo H743ZI2 via I2S+DMA. i was able to setup a fully working STM32CubeIDE project. as there is no I2S support in STM32duino ( yet ), i copied over the relevant code from the generated STM32CubeIDE project and added `#define HAL_I2S_MODUL...
