I'd like to use both external RAM and flash at the same time for an STM32H7 application. I'd like to get a better idea of what options are available for this. For example, 256Mbyte flash in memory mapped mode for execute in place and 4gb of SRAM indi...
Hello,STM32CubedIDE, STM407G DISC1 BOARD I am trying to trigger an external interrupt by using a button connected to PA1 pin. My configurations are below; 1-) I enabled 7.bit in NVIC_ISER register. IRQN_EXTI0 is enabled 2-) I enabled GPIOAEN...
Hi folks.Trying to put some debug info on MCU startup using SWO. I'm using pure CMSIS with 'STM32CubeF4 CMSIS Device MCU Component' and Arm GNU toolchain. I want to print some device info including ROM and RAM size.ROM size was easily obtained from s...
Hello everyone,I have an stm32f303cbt6 design (see image below) connected to an hub(USB2533) and an adum for isolation, i'm trying to run a USB device CDC example by creating a new project in the Stm32CubeIDE using device tool configuration. I select...
Hello,i tired to download the software pack to evaluate board EVLIOL4LSV1but the link does not contain a zip, just a view pdfs,no mather if in logged in or notSTSW-IOL4LSV1 - Software pack for EVLIOL4LSV1, IO-Link actuator for industrial tower light ...
Hi all, The goal is to read an external Flash memory connected to XSPI in Single-Mode. In the future, I will configure as memory-mapped, to see it as an extension memory of the MCU. I have already set up the XSPI peripherals with hdmarx and hdmatx ch...

I am working on SPI communication fullduplex using DMA between two Nucleo boards:Master: Nucleo-U083RCSlave: Nucleo-U575ZIImplementation:Slave Side:The slave continuously transmits integer data values like 100000, 100001, 100002, and so on, using the...
Hello,While debugging STM32H5 SPI2 (slave and master) in receive mode, the debug suddenly stopped and somehow I can't work in debug again.
Hello!I am having weird behaviour on my STM32G071 MCU.I set up the ADC to measure in sequence and I want to get an interrupt when the sequence has finished. The ADC is set up with DMA and I am starting conversions manuallty within my loop that runs o...
