I tried to use internal RTC with LSE clocking in device which has GSM/GPRS module (GSM part decoupled from MCU part by ferrite beads in power lines and resistors in data lines). In first PCB revision (no separate ground region under crystal) I notice...
Hello,Our board has an STM32N657 MCU connected to an IS21S08GA eMMC.We use an 8-bit bus, and SDMMC1 is configured to run at 32 MHz.In polling mode, read/write operations work, but are very slow — it takes about 1–2 ms to read or write a single block ...
Hi,I am trying to solve a strange programming related problem I am now having after updating the reset circuit of my STM32F439-based board. Below is a comparison between my old and my new circuit:The reason I made these changes is because this is a l...
Currently, I have a project using a secure application for the STM32N6570-DK. I am able to run and debug the FSBL and Application with the system in Dev Boot, but have yet to be able to attach and debug when booting from the external flash (Boot1 and...
Hi,I've flashed an application in the STM32N6570-DK board using a FSBL and Appli projects. The application boots fine.But when the application is running, I can't attach to it using the debugger and ST-Link.I've tried to open the debug port of the ST...
Hello.. can anyone advise the SWD pin for F767? and how these are connected to F767? PA13 PB3? Any schematic will be great !! I'm using it for debugging. Can anyone advise?
Using Nucleo-H753ZITrying to write to SD card using: FATFS FatFs; FIL file; FRESULT FR_Status; FATFS *FS_Ptr; FR_Status = f_mount(&FatFs, SDPath, 1); if (FR_Status != FR_OK) { printf("Error! While Mounting SD Card, Error Code: (%i)\r...
Hello,Is it recommended to implement an ESD protection on SWD lines of STM32L011D3/D4 mCU? I went through "Getting started with STM32L0xx hardware development" document and there is a Figure 15 which suggests to connect SWD lines direct to programmin...
Hello all,This is regarding the the problem after recent development from 18MHz to 22.8 MHz of operational speed of STM as slave operating with DMA transfer and SPI mode 01. Although the data sheet suggest maximum achievable speed of 31 MHz - I made ...
Hi,I'm planning to use STM32H562ZI as I3C controller with an I3C v1.0 compatible Target endpoint. Since STM32 I3C IP supports I3C v1.1.1, will there be any potential issues on RSTDAA, ENTDAA, I3C Private Write, I3C Private Read or other electrical pa...
