Resolved! Use of .c or .h files
Hi, I am curious one thing when using the HAL libraries. Just as an basic exapmle i assign LED1 to PB12 pin of STM32F070CBT6 as an GPIO_output. And i want to use HAL_GPIO_WritePin(GPIOB, LED1, LED1_SET); instead of HAL_GPIO_WritePin(GPIOB, GPIO_PIN_1...
Unpredictable behavior when extracting SVC number inside handler — sometimes causes BusFault
Hi everyone,I'm new to embedded programming and trying to understand how SVC (Supervisor Call) works on ARM Cortex-M.I wrote a small program that triggers an SVC call, and in the SVC handler, I try to extract the SVC number by accessing the PC that w...
STM32H7S78-DK examples exceed external RAM chip APS256XXN-OBR-BG max speed
Hello,in all examples for the STM32H7S78-DK - including the TouchGFX applications - the frequency for the external APS256XXN-OBR-BG PSRAM is set to 200 MHz:extmem_list_config[1].PsramObject.psram_public.FreqMax = 200 * 1000000u; But in the datasheet ...
STM32H7 is stucked in system bootloader when trying to jump to the application
We are experiencing issues when using system bootloader on STM32H7 MCUs. Enter to the bootloader is correct - when BOOT0 pin is held high and reset is performed, MCU enters system bootloader. We use USB DFU for communication with bootloader and PC ca...
HAL_Delay() function is not working after jump from Bootloader
Hello, I am working on NUCLEO-F070RB board, I have developed the Custom Bootloader Code to test the Bootloader functionality I am using blinky application with HAL_Delay(1000); When I run the blinky application independently the application is workin...

Hello all.Personal emotional outburst (just jump it if you don't work for stm):I can't understand how it's possibile, but every single time I trust STM and go for an update, everything stops working and I have to loose hours of my life trying to fix ...
Unable to Jump from Bootloader to Application loaded into SDRAM
Hi, My board consists of stm32h733 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from external flash(OCTOSPI) to SDRAM at address 0xc0700000.But running the code from this region causes hard-fault disabling the Debu...

fileX file name encoding
Hello,I am listing files on the SD card using fileX. My issue that some of the files contain Czech Characters (eg. č,ž,ě,š and few more). It seems that files with czech characters are read with shortened file names. (FX_MAX_LONG_NAME_LEN is set to 25...
