In looking at AN3155, USART protocol used in the STM32 bootloader, the following diagram describes the MCU's write protect command sequence from the device side:There is a comment at the bottom which indicates that only certain F and L series chips p...
We are using the STM32L071KZU6 in one of our designs and are facing an issue with bootloader communication over I2C. Specifically, some boards fail to enter the bootloader or respond on the I2C bus, while others function normally. Below are the detai...
I'd like to setup the DMA engine to use double buffer mode, but on different size buffers. It seems that there is only one NDTR register per stream, and the user manual says this can only be written to when the stream is disabled.So combining this in...
Hi, I'm using NuttX as RTOS on my STM32 board. I have a timer set in the DTIMER register, and in the interrupt handler of the SDMMC, if it detects a timeout, the way the code handles it is that does this: 1. disable all transfer related interrupts //...
Hello,I'm kind of newbie in the STM32 world, I'm more used with another brand of 32bits microcontroller that also have a "parrallel port" for interfacing external ram device.My concern is about the FMC on the STM32H7.I want to read/write a 16bits dev...
Hello ST Team, We are currently working with the STM32G0B1KCUX series MCU, which has 144 KB RAM and 256 KB Flash.Our objective is to measure the frequency of an incoming signal using TIM1 in Input Capture mode with DMA (Channel 2). Below are the key ...
Hello,STM32F411CE microcontroller.Where can I find, which of command the Erase or Extended Erase command is supported by the UART bootloader?There is a note 4 in the AN3155 (page 7 and,also see Figure 1 below) which says that the Erase (x043) and Ext...
I am trying to run the Secure Boot examples from STM32CubeL5 and have everything built, but on step 2 where I run `TFM_SBSFU_Boot\STM32CubeIDE\regression.sh` I am having an error where I cannot program the option bytes.(Another similar thread was wit...
Hey everyone,I'm working on a custom board based on the STM32H753 MCU. I successfully programmed it using STM32CubeIDE initially, but ran into an issue when trying to re-flash it — I got the error:"Unable to erase flash memory to reprogram it"To work...
Here in the below image from the Cube MX it suggests that, SET all the free pins as analog (to optimize the power consumption). How does it help. Also is it applicable to all the controller families?
