STM32 MPUs Products and hardware related

Resolved! Where would be placed instruction code for cortex-M4 core inside STM32MP1? Would M4 access external DDR to fetch instruction? Is there possibility for M4 code to be placed in internal SDRAM? Is there any limitation regarding the size of M4 code?

Resolved! STLINK-V3MODS for STM32MP1 Compatibility

Hello,I am in process of designing my own STM32MP1 powered device. I was wondering if I can use STLINK-V3MODS as a drop in replacement for ST-LINK/V2-1 in STM32MP157-EVAL reference design. I need the Virtual COM interface embedded in device.-Mark

Resolved! STM32MP157FAD1

Hello,I would like to ask you few questions since I have some unclearances about STM32MP157F MPU:1. If 933MHz DDR3L RAM was connected to the MPU according to the schematic, will the MPU automatically underclock it to max 533MHz?2. Is it possible to c...

Resolved! Difficulty with 1GB DDR3L memory routing and STM32MP151DAC1

Hi,I'm having some difficulty routing 1GB DDR3L memory with the STM32MP151DAC1. Both reference boards available for this product use different memory or pitch configurations. I found an Application Note, AN5122, that guides through memory routing, bu...

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...
