STM32 MCUs Security

Resolved! Design flaw in HAL?

I am using CubeIDE 1.11.2 with a STM32F3DISCOVERY board and have created an IDE project via the integrated CubeMX GUI.I want to activate read protection via HAL_FLASHEx_OBProgram as well as the write protection for the FLASH area of my firmware (appl...

Resolved! possible bug in F3xx Firmware?

When I compile a simple programm, using the CRC feature I get the following warning:In file included from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_def.h:30, from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal_rcc.h:29, ...

I am trying to implement Over The Air Update Functionality and secure boot from scratch for the STM32F303vctx Discovery board, could someone kindly provide me links to the appropriate resources, e.g application notes for the same? Thanks in advance

Hi, I want to ask if it is possible for me to implement FTPS and HTTPS using STM32F303RC and W5500, all datasheets I see exclude the F3 family, is it possible? Thanks for reading this, and sorry for wasting your time.

CRC computation

Hi all,I am sending a message via USART from STM32F303 (later to be moved from STM32F3 to STM32F427) to an X86.The message consists of 2 parts payload + crc ,CRC is calculated on stm32 using crc hardware engine and calling CRC_CalcCRC/CRC_CalcCRC16bi...

STM32F303: Loading CRC16-CCITT table at memory location 0x20000000 results in corrupted element 204

When loading a table (for CRC16-CCITT) in the RAM on the STM32F303, element 204 (value: 0x18c0) is corrupted. The value on load is 0x18c1.To test, I hooked up the openocd debugger, attached a breakpoint to the return statement and read out the conten...

HAL Problems with SPI(slave) + DMA + CRC(hardware) in stm32f373

I'm using a STM32F373 microcontroller as SPI slave and can't make it work properly using CubeMX and HAL functions.Master side is OK, confirmed in scope that byte string and calculated CRC for Tx are as expected.Slave side is programmed to transfer vi...

STM32F303VCT6 ADC4 Ch4(PB14) not working properly with Readout protection On

When i use STM32F303VCT6 ADC4 Ch4(PB14) without readout protection, it works good, i receives value 0 - 4096, as expected.But after Readout protection become On, value from ch4 adc4 i receives always is 0 - 3, not more

STM32 f3xx flash read out protection and option bytes programming: Mysteries solved

Posted on February 28, 2017 at 13:05Hello All,I have been trolling across several forums in order to be able to read protect my stm32f334 flash memory from within the code. I tried to use the hal functions provided in the stm32f3xx_hal_flash and stm...
