Hello all!Using STM32L433, RTC is initialized with LSE, works fine.In run, I want to switch to LSI and do certain steps and want to get back to LSE. What is the way to switch over RTC source LSE<->LSI ? I read some thing about backup domain. Please g...
I've inherited some source code for a custom board that reads EEPROM data from an Atmel AT24C02A chip. The code is based on the older STM32F103xx firmware library (not the newer STM32Cube code).Most of the time, everything works fine. However, it o...
Hi,I am trying to download firmware through USART into a stml031f6 device. The executable I can find from ST right now is the "STMFlashLoader.exe" but it is not compatible with stml031f6 (cannot find the stmap file for this device). And I am trying t...
Hi, I am currently using the stm32l031f6 which is a 32K memory device and I am trying to use the STMFlashLoader.exe, which is the command line version of the flash loader, to download firmware into the device. However, in the map directory for the ST...
Hi,I generated code for SD card and FATFS with CubeMx for STM32F407.How do I use BSP_SD_ITConfig (), BSP_SD_DetectIT () and BSP_SD_DetectCallback () to detect the presence of SD. I have found no example anywhere.Thank youPeter
Dear ST Team We are using STM32F765IGT6 in our design in a lot of 10 cards ,6 cards are not able to detect DFU and USART1/3 in boot mode.After programming they are giving proper console at USART 1 as per my design. Kindly suggest some debugging ste...
It doesn't work after a flash, but if I do a reset or reconnect the board, it works fine. Is this OK, or I miss something? I use SPL driver.The application is similar to the demonstration that came with the board (Nucleo-L152RE), except the part for ...
Hello,I'm trying to use the Quad SPI peripheral with DMA. In the DMA tab it does not allow me to click the "Increment Address" on the Memory section. Worse yet, anything I do in that tab is ignored. I modified every single thing possible and the o...
