Hi,MCU -stm32h743I have noticed that some RAMECC1 registers have a non-zero value on reset which is against the information given in the datasheet. For example, see the snapshot below:This is when the control is at the starting of main(). As per tabl...
MCU: STM32H753VI Scenario:I am working on the error management system for our firmware. Part of that is handling ECC errors in flash and RAM. I have been able to successfully inject and handle flash ECC errors, but am having trouble with RAM ECC. Pro...
Hi,We notice the startup time from power up can be affected by setting one GPIOB pin to input. The startup time here refers to the time from SystemInit() until main(). Basically it contains scatterload and __rt_entry to my understanding.Specifically,...
I notice that on the NUCLEO-H753ZI board schematic and BOM, the load capacitors are not populated for X2. My thought is that these caps must exist elsewhere, either built into the crystal, or integrated into the STM32H743.. But I do not see any menti...
I'm working with the STM32F407G-DISC1 development board. I would like to change the contents of RAM and hence I type ST-LINK_CLI.exe -w8 0x20000000 0xAB:ST-LINK_CLI.exe -w8 0x20000000 0xAB STM32 ST-LINK CLI v3.6.0.0 STM32 ST-LINK Command Line Interfa...
Dear sir, madami use my new stm32f465vit with my custom Board swclk pin always reset state.PA14 swclk pin always reset state 0v, after i connect 10k resistor swclk and PA13 swdio pin to 3.3v. make it pullup also same PA14 is 0v (VCC)so, I can’t conne...
In STM32H735IGT mcu I have initialized ADC1 and ADC3 in DMA method, also FreeRTOS is initialized. But ADC1 adc data is not obtained. But i can read ADC3 data. What may be the issue? One of the differences i have identified is continouous DMA request ...
I have two custom boards, one with a STM32F407 MCU that I use as a USART RS485 master, the other configured as a USART RS485 slave that echoes back everything I send from the master.I'm using the HAL libaray, and have successfully tested some simple ...
I have a firmware running on an STM32H755. All working fine until I added a secure bootloader to the firmware and now the firmware crashes when initialising TIM3.My setup: STM32H755 on custom boardSBSFU (1_Image)Cubeprogrammer and CubeIDE.I've pinpoi...
Hi everyone can anyone help me initialize LTDC driver and LCD screen. I'm using the STM32F7508-DK board and I don't know what I need to configure in STM32CubeMX?
