Hi everyone,I’m currently facing an issue related to bootloaders and FreeRTOS on STM32 microcontrollers, specifically the STM32H735 and STM32H730.Here’s the background:STM32H735 Development Board: I have successfully implemented a bootloader that jum...
We are trying to bootload an STM32L443CCT device using CAN bootloader.The documentation for the STLINK V3 details that by using jumper JP7 and CN5 to connect, we should be able to communicate with a device which has been triggered into bootloader mod...
I'm building a loop pedal for guitar, and I need to store audio buffers to be looped over. The 1MB provided by the STM32H743VIT6 won't do for recordings longer than 5s on 24bits + 44.1kHz audio quality. I bought some ESP-PSRAM64H chips, which can ope...
I'm using an STM32H753ZI, specifically the Nucleo H753ZI board, to read data from an ADS8556 adc. Upon signaling to the ADS8556 to start a conversion, a BUSY signal on the adc goes high and falls when the data is ready to be read.I currently have BUS...
I used MultiQ example 'LPBAM_DMA_MultiQExec' I change code for U545REQ board but it doesn't work.i found some issueThis is 'LPBAM_DMA_MultiQExec' codetatic void MX_LPDMA1_Init(void) { /* USER CODE BEGIN LPDMA1_Init 0 */ /* USER CODE END LPDMA1_...
Hi, I am using the STM32U575.In my application, I have to transfer ADC readings to a destination buffer. I have set the DMA source address to the ADC data register (16-bit), and the destination address to a memory buffer start address. The data width...
Hi,I am using STM32H753 in my designCan I short JTAG reset, NRST of MCU and supervisory IC reset ? Will it create any issue while debugging via JTAG interface?
Body:Hello STM32 Community,I’m facing an issue with EXTI interrupts on my Nucleo-G0B1RE board (STM32G0B1RE). The EXTI interrupt doesn’t trigger, even though the configuration appears correct, and I’ve tested both hardware and software triggers. I’ve ...
How does the bootloader in the STM32C071 system memory generate its 12-character USB serial number string descriptor (e.g. "205537C24236")? I notice some similarities between this serial number and the 96-bit unique device ID at address 0x1FFF7550, ...
I'm developing a tool to gang program STM32 products. I'm currently working on the STM32F411 (reference manual RM0383) and the FLASH_CR register SNB field mentions two sectors: user specific sector and user configuration sector. The user configuratio...
