Hello,I have second stage bootloader in place and want to change RDP level from it (0 to 1 and roll back when doing firmware upgrade).However, the problem is, once RDP level is changed to 1, bootloader is not able to change it back to 0. I've to chan...
Hi,I m testing SPI TXE flag with the following code:void TestSPI(void){ GPIO_ResetBits(GPIOA, GPIO_Pin_4); SPI_I2S_SendData(SPI3, 0); while (!SPI_I2S_GetFlagStatus(SPI3, SPI_I2S_FLAG_TXE)); SPI_I2S_SendData(SPI3, 0); while (!SPI_I2S_Ge...
Hello everyone:I have a problem with my project.My project is to use STM32H750UBKx + Keil MDK5 IDE to design.The customer bootloader runs in Flash, and The application runs in Quad SPI NOR Flash (or SRAM).Problem: When I execute the code "JumpToAppl...
I have below questions:1. Using NRST pin make LOW which flag would be SET in firmware? 2. If we do board power ON and OFF, which flag would be SET in firmware?
I have tried everything I can think of to get part to program, I still get this:The elf loader Sector Erase function fails.Memory-Loader errorError occured during erase operation!Programming error @ 0x08000000!I have tried STL CLI, JFlash-lite, JFlas...

Hello,I am working on STM32H745 controller. I want to share a variable between M7 and M4.Example: Variable named counter will be updated by M4 after some period and same has to be read by M7 for further processing.Can anyone help me with suitable app...
Hi everyone,I have configured my ADC on STM32F405 in Scan mode to read 5 channels. What I like to do ist to make a single DMA transfer to sample the 5 channels more than one time (e.g. 10x5channels = 50 elemet DMA transfer) To average the data after ...
The output push-pull implies either 0 or 1 - never floating. When do we use the output push-pull with pull-up or pull-down capability? What is the application for the output push-pull with pull-up or pull-down configuration?
Hi. Setup is simple:TIM2 creates the ADC_EXTERNALTRIG_T2_TRGO signal, which starts ADC. ADC is configured to use DMA to transfer the data to the buffer. hadc1.Instance = ADC1;hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;hadc1.Init.Resolution ...
