Resolved! Help needed in configuring I2S supply voltage

Hi,Are there any references for configuring the I2S supply voltages in device trees for STM32MP135-DK.From the I2S module currently we are getting the output level as 5V, is that expected or is there any way to change that from 5V to 3.3V.

Resolved! In EXTI, how to know which port generates the interrupt?

Hi,After reading the document I understand the interrupts are handled by pin#, and we set GPIOsel within EXTI_ConfigTypeDef.My question is how do we determine which port generates the interrupt?Suppose I use PA0 and PB0, and I only want to use one ca...

STM32MP1 ldrex/strex support between A7 and M4 cores.

Hi,I'm searching any information about how exclusive access (LDREX / STREX instructions) is implemented in STM32MP157 silicon. Unfortunately, it seems that ST assumes that this information is obvious.Based on ARM documentation, the synchronization is...

STM32MP1 - MAC address

Greetings,  I have a few STM32MP1 boards. One of which I have configures the OS on, and custom applications.I copied the SD card and put it in another one.  The MAC address is the same. I read an STM article about the MAC address and "fuse sense 0 57...
