Hello,I ran into a problem with Ethernet using an STM32F407VET6 microcontroller a few weeks ago.That time I have searched this problem and found somebody facing the same issue and conclusion, but I did not found that thread now.So using the latest HA...
Hello. This is my first post here. I'm pretty unexperienced at the hardware side of MCU's and I want to debug my STM32F304P6 processor (on an unofficial board) through debugger of STM32F407VG Discovery Board. I connected SWD pins ( 2nd to CLK, 4th to...
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...
