STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I'm using a STM32H753 with external RAM. We were using it for LCD framebuffer. Now we are trying to migrate the stack and heap to the external RAM, when we run the code, getting hardfault on lines where std::array is declared. Any idea on how to debu...
Hello everyone,I am currently working on a bootloader project for the STM32H735, using the pre-configured ExtMem_Boot project provided by the STM32CubeIDE. However, I am encountering an issue when trying to write to the external flash memory at addre...
Hi!I am writing a bootloader for an STM32H7S3L8, that received the application binary over UART and places it into flash, specifically on address 0x08008000, and I am getting hard faults when jumping to the address.If I "install" the application AND ...
Hello, I am looking for a solution to my problem.I am using an STM32C031 to light LEDs using SPI signals.I am using a connector to connect the STM32 mounting board to the LED mounting board. The connector connects the DC power supply and the SPI sign...
Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send...
Can anyone help me find the Peripheral Bus to enable Clock for the GPIO Port on the STM32L073RZT6 microcontroller? Please find the screenshot attached.
Hi,Since there is no obvious to ping an ST rep directly from an ongoing thread, I'm posting these questions in a new thread in the hope that ST will respond with answers. These arose during discussion in another thread:How Can I Provide a 1mhz HSE B...
Should ICACHE be invalidated when a double ECC error occurs?
Hello,I am using the stm32u5 SBSFU application and I am trying to implement my own 64 MHz clock. But when I change it from 160 Mhz to 64 Mhz the application does not work. Can the SBSFU clock work with less than 160 MHz or does it have to work only w...
I'm working with an STM32G474 microcontroller and need guidance on how to write 32-bit data to flash memory. Could someone provide me with a proper procedure or example code that demonstrates how to accomplish this task efficiently and correctly? Any...
