my host interaction with STM32G431C8T6 SPI bootloader are functioning for a lot of jobs such as RW, but not for the whole-chip CRC. Here is the Logic analyzer captured data:Host=>BL, BL=>Host5A, A5A1,A55E,A5 cmd to run whole chip CRC00,A5......00,A50...
When doing triggered (EXTI2 line) DMA transfer with SPI in circular mode I often don't get the expected result. If I do the DMA transfer (non-circular) from the EXTI2 interrupt everything is fine.Code transmit 10 bytes, receives 10 bytes each transfe...
Hello!I'm trying to run SPI in Transmit Only Master mode.It's strange - result of HAL_SPI_Transmit is HAL_OK but I can't see any signals on SCK and MOSI pins.main.cint main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Config...
HI, I m trying to send a 16 bit word using SPI HAL to a SPI external interface driver. SPI is configured as:-Transmission master-16bit data TX-MSB first.This driver requires first address of the register and then the content to be received. I created...
I've got a design with a STM32F405RE bootloading onboard STM32F722RE via SPI1.I've implemented SPI bootloader host (mostly same as serial with addition of adding extra 5A frame and dummy reads in a couple places) and individually verified commands li...
Hello, STM32 Developers/STM32 Enthusiasts!I got a NUCLEO-U5A5ZJ-Q and tried using SPI with GPDMA to drive an SSD1309 OLED display, which works fine without DMA.On this device we use GPDMA, which is new to me.I managed to successfully transfer the fir...
Configured Master/Slave SPI. (1). trigger Interrupt SPI receive.(2). Interrupt and receive a data(3). Trigger interrupt SPI receive again(4). Never trigger SPI Interrupt receive.... HAL_SPI_Receive_IT(&hspi1, SPI_Receive_Buffer, SPI_RECEIVE_DATA_LENG...
Dear everyone,I'm not able to know is it possible to add an external flash (SPI) to a MCU for saving data (FATFS) AND get the data available on USB Mass Storage.A lot of library exist for SPI flash, the most knowed >"https://github.com/nimaltd/w25qxx...
Hello,I have a board with STM32F407VET microcontroller, W25Q16 and microSD connector.Writing and reading information from W25Q16 without USB works (using library https://github.com/nimaltd/w25qxx).SD card via USB works (I found an example somewhere, ...
This occasionally leads to (especially if only transferring one byte) the interrupt executing before the function has unlocked the process, leading to the function returning HAL_BUSY if you were to attempt to initiate another transfer in the transfer...
