Hi, I have been trying the Flash dual boot example from version1.3.0. I am following the steps as given in the readme.txt, flashed the bank2 FW from location 0x08040000 and used the debugger to flash the bank1FW. I triggered a bank swap by pressing t...
Hi, I'm using STM32L4R5 and I'm planning to use the HSE, and already selected a crystal (Abracon LLC - ABMM2-8.000MHZ-E2-T https://abracon.com/Resonators/ABMM2.pdf).Freq - 8MHzCL1=CL2 = 24pFgmcrit = 0.4548Gain margin = 16.49For external resistor Rext...
On our project 4 (out of 1200) devices startet to have problems after a few weeks of working. It turned out they had a HSI16 of 15MHz @ the default calibration settings. A recalibrating brought it back to 16MHz, but questions arises:How can the HSI16...
Hi ! there is a question about my program: I use a bigger array ,size is 10K , in my app program ,my IAP bootloader program can jump to app program ,and it works. but when I change it up to 20K , app doesn't work.And the app works even array's siz...
Hi, I am using stm32f730i8 chip set for my application, whereas I am communicating the peripheral through spi where I need high frequency clock. But currently I am able to operate with 2MHz if I increase beyond that the spi clock is getting skewed.Pl...
Hi all, I'm working on a project where I am using an STM32F3 (master) to communicate with an STM32G0 (slave) using SPI with DMA. The G0 performs a task and can receive commands, and have it's "registers" (ie. state data) read out over the SPI. I want...
Hi, I am working on an STM32L476RCT6 and I use STM32CubeMX to configure the peripherals of the microcontroller.Currently the microcontroller runs on MSI, whose frequency is set at 8 MHz. The clock configuration is as follows :I want to use the USB in...
I'm using a STM32F411CE ("black pill") with STM32 Cube IDE and have been following this tutorial, except I'm using a different board and 5 ADC channels instead of 1. I have set them up as in the attached .ioc file. I would like to use a ping-pong buf...
Dear allI have generated a test project via CubeMX, for STM32F107VC MCU for sending data as a MASTER SPI to a slave device (another STM32 device) by using Interrupt mode.They system is running FreeRTOS 10 (tick on systick) and HAL (tick on TIM7).TIM7...
I have a demoboard STM32H735-DK. I develop a demo for my customer. All OK. But when I supply the card (with USB cable) the application-firmware doesn't run: I have to press the button reset for start it. Why? Thanks for your answer.
