Hi all,I generated code in STM32CubeMX for STM32L081CBTx controller with AES enabled.I built the generated code (without modification) in STM32CubeIDE, but it failed with warning:../Core/Src/stm32l0xx_hal_msp.c: In function 'HAL_CRYP_MspInit': ../Cor...
Hi ST community,I have a fully functional application on my STM32L072. The problem is when I tried to enable RDP, nothing works anymore.After flashing the application I tried to connect with ST-Link, the option bytes are set correctly and it is not p...

Read Protection has been set in the STM32 chip .In this case, how to judge the chip is in the read protection state through the bootloader program of the chip.I now is to send the erase instruction, if return NACK, judge chip is in the read Protectio...
I am confused about the setting of the SPI CRC functionality: it is not clear what CRCSIZE is doing and how to set it. I understand that to get a N bits CRC you have to choose a N+1 bits polynom, but why is the length of the CRC not deduced from the ...

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...
In the code it says the following:/** * @brief This function writes a data buffer in flash (data are 32-bit aligned). * @note After writing data buffer, the flash content is checked. * @param pFlashStatus: FLASH_StatusTypeDef * @param pD...
I started a new project, and my security requirement states that user authentication is required when updating firmware.I wonder if there's a feature for this, and if not, can the bootload side be modified to meet this requirement?I searched and foun...
