STM32 MCUs Security

I have enabled level 1 rop in stm32f030c8, now my code is not working in device and m not able to load fresh code or debuge it using attolics true studio.

here's my code for RDPprotection:void Flash_SetRDPLevel(uint8_t ReadProtectLevel) //level 1 (0xBB){ uint32_t tmp_reg; Unlock(); OB_unlock(); /* Read RDP level bits */ tmp_reg = (FLASH->OBR & (FLASH_OBR_RDPRT1 | FLASH_OBR_RDPRT2)); //if (tmp_re...

Resolved! STM32F030 Locks up after being placed in Level 1 Flash security mode by Option byte

Main is entered,(for testing I enable the GPIO and turn on an LED to validate that cpu execution has entered main() --- then I set up the PLL, and GPIO - then test if the MCU has option byte set for Level 1 - if not I set it.I reset the device and it...

CubeMX (F0 v1.11) CRC failed for STM32F030F4P6? Code generation is not correct!

Please, check the default CRC config and it code produced for STM32F030F4P6 for the v1.11 firmware. It create the errors in EWARM v8.40.2 project (see attach). Revert to v1.10.1 with no problems.Is there hotfix for v1.11?

Is there any resources that explains the work flow of the hardware CRC32 or how to make it works as standards CRC32?

I have a module that uses the STM32F091RC MCU and trying to connect it with software using C# language.At the first the connection has worked properly, then I've used the CRC32 to verify the sent data but it didn't work.Ive read the "Application note...

Optimizing X-CUBE-CRYPTOLIB for memory constraint

Hello!I want to use Asymmetric Crypto algorithms like ECC or RSA for my FreeRTOS project running on STM32F051K8. The controller has 64 KB of flash. Since X-CUBE-CRYPTOLIB occupies quite large memory footprint, my FLASH is getting overflowed by the .t...

If I program the ST32F072 part with Level 2 security can I erase the part and reprogram? I understand the Level security remains at Level 2. I am using a Cyclone Universal programmer.

CRC16 for STM32F030

I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.

STM32F0 read out protection problem

Posted on March 30, 2017 at 10:13Hi,I would like to use a software read protection on STM32F0. I've made such a function:PROTECT_STATUS ReadProtectionConfig(uint8_t ProtectionLevel){ uint8_t status = OK; FLASH_OBProgramInitTypeDef OB_Init; HAL_FLASH...
