Resolved! Custom size erase of Internal Flash or Override of existing data for STM32U585 series Internal flash
I am working with an STM32U585 microcontroller, and I need to perform read, write, and erase operations on the internal flash memory (Bank 1) with TrustZone security enabled. The page size is 8 KB, and I am encountering an issue when trying to write ...
Resolved! RAMECC1 register reset value
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...
ITCM and DTCM RAM ECC monitors triggering HAL_RAMECC_DetectErrorCallback
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...
Resolved! Undocumented behaviour STM32C011F4U6TR
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,...
Resolved! Does STM32H743 have integrated crystal load capacitors?
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...
Resolved! Unable to modify RAM using ST-LINK_CLI.exe
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...
stm32f465vit PA14 swclk pin always reset state.
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...
STM32H735IGT MCU- ADC DMA Multi Channel Data is Not Obtained
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 ...
STM32F407 USART failed to receive when using DMA to transmit
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 ...
