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...
Hello everyoneI've hit a bit of a snag with my PCB redesign (V2) featuring an STM32F429ZIT6. While the initial version (V1) worked like a charm, some layout changes and component swaps (SN74ABT16245ADL to two SN74HCT245DWR) in V2 are causing issues w...
Hi,I need to service an external watchdog when a flash sector is being erased. The sector being erased is in the same flash bank where code is executed from. Before I try to jump and run from RAM I had a few questions.Where is flash stall discussed...
Hello,i have problem with custom board assembled with STM32F767BIT6. I'm trying to interfacing LCD-TFT DEM 800480K3 TMH-PW-N which is assembled by HX8264E, HX8664B drivers. I'm using RGB888 interface configured via STMCubeIDE filled by resolution 800...
Hi,I want to update multiple HRTIM registers with a single DMA request on a STM32G474RE. To do this, I am trying to follow this simple Getting started with HRTIM tutorial, which has a section "#To_go_further_about_DMA_burst" on the board "B-G474E-DPO...

Hi, I would like to know method and sample code storing data without erasing whole memory page. I do refer example FLASH_EraseProgram, but i have wrote program that almost finish up the flash memory, if i erase a page, a 2KB page, it will erase my co...
Hi guys,I could set MCU into bootloader mode manually by using PH3/Boot0, but I can't get trigger bootloader via SW... I did check previous posts, but somehow it does not help.HW setup: I have dev board with STM32L431. It has USART1 (PA9, PA10) conne...
HiI would like to debug STM32F303RDT6 using a combination of Keil and ULINK2.When I start debugging on the target microcontroller (STM32F303RDT6), **Not a genuine ST Device! Abort connection** is output as shown below.We investigated the cause.I foun...
Getting this error and have no idea how to troubleshoot it further:Break at address "0x800c44e" with no debug information available, or outside of program code.<signal handler called>() at 0xfffffff1Break at address "0x8004bf4" with no debug informat...
Hello,I'm currently sending AT commands to the Grove LoRa E5 module from Seed Studio, when I send commands like "AT," there is no response from the module. I've connected the module to the USART of the STM32L476RG board. If anyone has encountered and...
