Hello,I would like to implement an I2C master on an STM32F103. It's pretty straightforward to select the IO's using cubeMX and to generate the code, but I don't want to use either of the available pins for I2C (PB7,PB6 or PB9,PB8). I need to use PB5 ...
Due to stm32f303rct6 refrence manual (RM0316) p. 243, the reset value of GPIOA_PUPDR register for PA8 and PA11 are equal to 00. This means that the output of them are not pull-up or pull-down under reset state,but In my practical test, PA8 and PA11 a...
Hello,I'm developing on an STM32F207 (datasheet). I am attempting to modify a couple of the internal Flash sectors (the 128kB sectors 10 & 11 to be specific). I'm trying to figure out how to do this in a way that will not block the CPU. Let's say I'm...
I am trying to write data in the flash of an STM32F446RE, sector 5.My linker script is configured so that .user_data goes to 0x08020000, and:__attribute__((__section__(".user_data"))) char userConfig[4] = {1, 2, 3, 4};Is my user Data.If I read it aft...
If I try to put a method in the .data section using the below code, the microcontroller hangs when I try to call it. Is it a wrong way?(When I check in the disassembly it appears indeed in the RAM)__attribute__((long_call, section(".data"))) void my_...
I probably should have posted this many weeks ago but after the hell I've been through I thought it worth posting this as a question that I now believe I've answered myself but in the hopes of saving someone else a few weeks of hell here goes. For th...
I want to migrate from STM32F030 to STM32G071. Please tell me if errata section 2.25 (Overwriting with all zeros a Flash memory location previously programmed with all ones fails) could affect my custom bootloader or flash save functions from main...
Goodmorning everyoneA few weeks ago I started working with this board (NUCLEO-H743ZI2) and STM32CubeIDE, for the moment I have only faced simple problems such as timer configuration, interrupt generation and ADC readings.Now I need to program the boa...
Hello,I am trying to write to flash memory from the firmware itselfIt looks like the Erase process hangs for 2 seconds or so but works, but the writing process seems to totally freeze the MCU. Below is the code I am using. Any idea ?FLASH_EraseInitTy...
