Hi, I am using STM32L452 Controller and I would like to use LSI for RTC which is not an accurate clock source.I referenced the following manual and adjusted the pre-scaler as 2.8 RTC prescaler adjustment with LSI measurements - page 23https://www.st...
From time to time I run into a Problem that the STM-Bootloader doesn't respond when I try to activate it.What I do:Hold reset pin of STM low for at least 2s. Then set Boot0-pin to high (Boot1 is connected to GND with a 10k resistor).After another 1s ...
Hello everyone,I am student and using the FATFS middleware to log sensor data to a uSD card using stm32f746g dev board. The data gets logged only for the first few minutes (8 minutes) and then the f_write() returns a status as FR_LOCKED (16).What cou...
In the actual SVD file (ver 1.7) the Ethernet peripheral registers are incomplete, Ethernet_MAC section actually we have Ethernet DMA registers, and no register descriptions for ethernet MAC. Beside even the Ethernet_DMA registers are showing incorre...
I've built a simple STM32CubeIDE project with just the SDMMC1 peripheral mapped, a GPIO pin for the SD Detect pin and the FatFs middleware enabled with DMA per a discussion elsewhere on this forum. I have a Waveshare microSD card jumpered to what I'm...
Hi, I want to synchronize the my threads execution using the mutex.here is my code /*---------------------------------------------------------------------------- * CMSIS-RTOS 'main' function template *-----------------------------------------------...
Hi,we are starting to learn about LwIP in order to create a http server in a stm32f4. At this moment we have a functional hardware that act as http client using a modem with AT Commands (the quectel MC60). However, now we have been asked to create a ...
I am trying to program the STM32F401 flash on our board in DFU mode. I am using the dfu-util tool in my Linux computer.I am using the following code to flash and jump to application code.dfu-util -a 0 -s 0x08000000:leave -D <location-to-binary>.binAf...
I've download the CMSIS pack for STM32H7 series. ST implement an I2C driver function like this:int32_t I2C_MasterTransmit (uint32_t addr, const uint8_t *data, uint32_t num, bool xfer_pending, I2C_RESOURCES *i2c), but the website, https://arm-soft...
