Debug External memory code execution on STM32F7x0 Value line with SW4STM32

How can I debug a program that is being loaded and running from the QSPI external memory of the STM32F750 using the XiuP model?

STM32CubeMX project open bug : I can't open my project file since the last update.

Hello,Since the last update of STM32CubeMX 4.26.1, I can't open my project file anymore.Right after clicking on the 'open' button, the software freezes and one of the processor cores stays at 100%. The only available action, then, is to close the app...

STM32F429 IAP not working

Hai, I am using stm32f429igt controller I am trying to use IAP and found one example with stm32f4 cube package. While trying the example the code is not getting uploaded when I tried to upload it still waiting for the file can anyone help me how to s...

Where can I download Demo code for STM32F769-DISC0? Is it possible to program the board in ubuntu 18.04? If it is, then please provide the tutorials or guidance urls.

Recently we bought the STM32F769-Disc0 development board. We want the source code of demo project and how to compile the code in ubuntu 18.04 or any versions of ubuntu.

Open-Drain output connected to WKUP pin

Hi,I'm working with an STM32L073RZ on a custom board, using MbedOS 5.12.0 bare metal. The board is a very low power weigh scale that is normally in Standby mode and is awoken by an accelerometer (connected to PC_13), an NFC chip (connected to PA_0). ...

Resolved! STM32F429ZI aborting DMA transfer on USART3 prematurely

On an STM32F429ZI, I'm using USART3_RX to receive information via DMA into a circular buffer. The buffer is 4096 bytes long.If I send 1 or 2 bytes at a time (i.e. with a delay of ~100ms+ between transfers), things work correctly. By "work correctly" ...

Timer synchronization still has offset

Hello,I am trying to synchronize two PWM outputs on an STM32H7: TIM4 channel 2 and TIM8 channel 3N.To do this I am using the HAL synchronization functions, setting TIM4 up as master with "HAL_TIMEx_MasterConfigSynchronization" and TIM8 with "HAL_TIM_...

Where is the VREFINT_CAL for STM32L072z

Hi everyone ! I read in the datasheet that I need the VREFINT_CAL to calculate my real VDDA but I don't find it in the datasheet. In every other model's datasheet you can find the VREFINT_CAL easily but not in the STM32L0 one. Is someone kno...

PA6 is always biased with 3.3v with OPAMP2 enabled on NUCLEO-L496ZG. WHY?

I'm trying to use both internal op-amps to sample analog inputs with ADC1 and ADC2. When the op-amps are setup using CubeMX (latest version), 3.3v stays present on PA6 input. PA0 works as expected. Both ADCs sample correctly but the waveform input th...

Resolved! A question about Vdd, VddA, Vref and clock frequencies

Hello,we want to build a system with STM32H7, hopefully one of the new up to 480 MHz devices. And we really need a high clock of 400 MHz and above. On the other hand we need low power and we use ADC and DAC, both requiring a 3.3V Vref.Now my question...
