I am seeing the same issue as this question here :https://community.st.com/s/question/0D53W00000HyV6FSAV/fmc-with-dual-core-stm32h745I can configure SDRAM access on the STM32H745 for the M7, but when running two cores I cannot get access from the M4 ...

I might be missing a trick here, but it seems that most (if not all) DISCO / EVAL boards expose the same I2C bus externally that is used to communicate with onboard peripherals.This makes perfect sense with DISCO boards as they are small / low cost. ...

I am posting this more as an open question, and perhaps to help someone else...When configuring SAI2 for Audio in CubeMX I had some issues which stemmed from MCLK not appearing to work correctly for the Audio Codec. This would cause the wm8994 to bec...

Firstly come context:I have seen some differences in my sandbox project between what CubeMX auto-generates for my STM32H745I-DISCO and working examples I can download from github. Different GPIO settings which seem significant, for example. The ST gi...

Thanks for the clarification. I guess I didn't consider SAI to be a "periperal" in that sense as it's part of the SoC.

On a discovery board with a wm8994 should I be able to both read and write all control registers over i2c?I am trying to verify settings by reading them back after writing. I get reliable reads from some of the lower registers (under 0x0100), but abo...

Thanks for your help Sara. I think I have the baseline info I need now. =)

Hi Sara,Thanks for the feedback. I am suprised the SDRAM timing is correct. The values I have been using are significantly different (lower), but that is on the M7 side. So maybe that is why.Regarding the Active Height and Active Width.. All of those...

Hi Marc,Thanks for your reply. I'll try to answer your questions..There are several example, in the STM32H745I-DISCO directory from GitHub. Which one are you referring to ?I am referring to the BSP driver code here : https://github.com/STMicroelectro...

Shared SDRAM via FMC with dual core stm32h745

Are there any DISCO or EVAL boards for STMH7 MPUs that offer access to an unused I2C bus for external peripherals?

Is CubeMX reliable at generating a "default" config for a discovery board?
