Hello guys, recently I designed a PCB board using STM32H743IIT6 and I encounter a problem when I try to run code in sdram. The details are described as below.question: I have a demand jumping to run a user program(function) in the sdram. B...
Hi, I have developed a circuit using STM32h755zi, i am sending some serial data from a custom board to PC using USB CDC class. It works fine when i use a Type C to Type A cable but when i try to run the board using a Type C to Type C cable it only ru...
Hi!I have a custom STM32H753ZIT6 MCU based board for which I am using SWD in order to bootload/program the MCU. To interface the SWD to either the STLINK or other programming modules similar to it, does anyone have any recommendation on what connect ...
Hello Everyone!I am facing an issue while trying to enter the STM32 bootloader via USART1 on an STM32U599ZJT.Issue:When applying 3.3V to BOOT0 and performing a single reset, the MCU enters a reset (boot?) loop, which persists until BOOT0 is deasserte...
From Nucleo-G474RE I am not able to read the Read JEDEC ID of my external flash W25Q16JV ,chipselect not going low on sending command.Verified all connections and quadspi configuration multiple times/* QUADSPI1 init function */ void MX_QUADSPI1_Init(...
Hello everybody i would like yo know the feed direction of the tape for the part STM32H7B0VBT6TR. i can't find any information online regarding it. can anybody help ? thank you regardsaliette
Hi,I'm trying to configure pin PC14 to be used as SDA signal as it stated in the datasheets STM32C031C6 and STM32C031G4: To configure the pin (and the the I2C) I am using: void SDK_I2C_Init(SDK_I2C_HandleTypeDef *hi2c) { LL_I2C_InitTypeDef I2...
Hello,I have written a Flash bootloader for the STM32H743 for our custom application PCB. In a nutshell, the flash bootloader check an external flash memory IC with SPI on the custom application PCB if there is a new image to be flash and do it if it...
I am stumped and frustrated. I wrote some test code to test UART4. It worked fine. Then I moved the test code over to my main project and now I get no UART interrupts. Both code sets run on the same hardware. I have checked to make sure the UART RX w...
Good day folks, I trust you are well.I am interfacing with a APMemory 256Mbit RAM (APS256XXN-OBR) via the 16 way XSPI.The RAM registers can be configured correctly at 100MHz, as well as the whole 256 Mbits can be accessed via Mmap.For Configuration I...
