Hello,I am working on an STM32WB project where I need to erase and write to the flash memory. I have utilized the flash_driver.c files that I found in the STM32WB examples. I tried to integrate these into my project (which does not use FreeRTOS or BL...

Hi,I'm currently trying to figure out how to properly upload a program to an STM32. I'm using VS Code with the STM32 Extension. I've noticed an issue where uploading the program using either a .elf file or a .bin file results in different values in a...

Hi, I use an STM32WB with the BLE stack. In my code, I need to write data to the flash memory (writing new firmware to a prepared memory area). Unfortunately, when I attempt to write to the flash, an error occurs. Is there anything special that I nee...

Hello,I am working on a project using the STM32WB55 and its BLE stack. I am trying to implement a custom service with more than three characteristics. However, when I add a fourth characteristic, the function aci_gatt_add_char returns the error code ...

Hello,I am using an STM32WB with a custom bootloader, which is currently simple and only knows how to jump to a specific address to start the application. I upload firmware using debuggers (STLink V3 and JLink). When I upload the bootloader and the a...

@Lubos KOUDELKA Thanks for the answer. I need to clarify something please. I'm using BLE (I have the Stack + FUS loaded). However, I have a custom Bootloader that needs to erase and write to flash memory, and only when it jumps to the application is...

Hello,Thanks for your guidance - I tried using the `flash_driver.c` as indicated in the example, and it works! However, this is only the case if you have STM32WPAN and FreeRTOS enabled in CubeMX. In my application (Bootloader), I don't have either Fr...

Thank you, but I think problem is somewhere else:Im having trouble with uploading programs from VSCode to an STM32 microcontroller. In my code, there is a 4-byte section that remains unused, likely due to memory alignment. When I generate a .bin or ....

I just found out that it works :-), but I'm not sure if there should still be some protection using a semaphore - in case the other core with M0 and BLE stack is accessing the flash at the same time.

I tried, but I couldn't find out what it means.
