I'm experiencing a very, very strange behavior when running debug sessions in STM32CubeIDE. Sequential sessions alternate between correct execution of my main() entry point (and execution stops there, as expected) and unexpected entry into the bootlo...
The power supply scheme indicates to use 100nf for vref and vdd, but in the General PCB design guildines section (Figure 51 and 52) indicates that 10nf power decoupling capacitor should be placed. I am confused which capacitor is suggested for adc de...
should the pullups on JTAG should be given for JTAG in STM32H757XIH6, also are there any extra consideration taken care while using ARM JTAG. If pullup is not necessary, why is it so.

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...
I'm trying unsuccessfully to erase a 4K sector at 0x73ff0000 using STM32CubeIDE code, but the STM32CubeProgrammer works fine. I've tried using BSP_OSPI_NOR_Erase_Block() and MX25LM51245G_BlockErase() with no luck. My code base is the HTTP_IOT_WebSer...
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...
