Hello, I want to add a SDRAM chip to my board. Processing the images with internal RAM is insuficient. Reading the manual for FMC part I'm not sure how the bandwidth is working. If I have a chip with 8/16/32 bit, is pretty clear: one chip and that's ...
Hello ST community,I have some troubles with dummy cycles using Quad-SPI interface in DDR mode on STM32H743 and STM32F746.I am trying to read data from IS25LP080D QSPI flash with FAST READ QUAD IO DTR MODE OPERATION (0xED command). It is 1-4-4 mode.I...
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
Hi, I am using the STM32H755ZIT6 dual-core microcontroller.The internal Flash memory has a sector size of 128 KB and a page size of 4 KB. In my application, I perform erase and write operations on a specific Flash sector. If a power failure occurs wh...
Hi everyone!Could someone help me to understand a problem with STM32G070.We have deployed approx. 50-60 devices with stm32g070 MCU that saves some parameters in FLASH every 24 hours. I know that according to datasheet FLASH memory endurance for this ...
Hi, I'm currently working on a project with an H755 board.The project uses UART communication. I'm developing it on a Windows 11 computer, and it generally works fine on that computer. So far, there are no issues.However, after completing the project...
1.AN5959 for STM32H523 has a note PB8/PB9 Not available for LQFP48, UFQFN48, WLCSP39.LQFP64 is not mentioned there but it has only PB8 pin and no PB9 pin. That makes it unusable by boot loader. So why it is not included in the note?My question is if ...
Hi,Few days ago i've encountered a strange behavior of the comparator at STM32G4. I investigated the problem under controlled conditions (used Nuclo kit instead application PCB) and the result is startling.Comparator 4 configured to get positive inpu...
Hi all,I am working on firmware that involves SPI communication using a Nucleo board (Nucleo-L4R5ZI-P) with an STM32L4ZIT6 microcontroller.I am trying to establish communication with an SPI slave device. The chip select (NSS) signal is expected to be...
Hi,I am unable to flash or erase two of my STM32G030F6P6 boards. The issue started after I tried to configure the PA14 pin as GPIO_EXTI14 in CubeMX. (on two boards)After flashing the binary I was not able flash the MCU anymore. I get the error "Error...
