I have a user bootloader I have used across various STM32 parts over 12 years. In production RDP level 1 is enabled and this has always been fine for various STM32F1, F2, F4 based products we have in production, and for thousands of units in the fiel...
Hi,My project is based on STM32L15xx microcontroller. I know, that internal FLASH Read Protection may be enabled during programming an image by STMFlashLoader with --erp option. My question is: can I compile my image with internal FLASH read protect...
Dear all,I have a question regarding the read-out-protection on STM32 L1 series (STM32L151CB-A) and I was wondering, if the same problem occurred to anyone of you before.I am booting from internal flash memory (BOOT0 = GND) and set the option bytes R...
According to the integration guide (an5056) it should be possible to use the flash memory to store user data (chapter 8.2) . However, when turning on the MPU protect define the controller goes into a memory fault when accessing the eeprom for reading...
Hi there,I am trying to understand the state of the option byte values in flash after a forced mass erase (changing RDP from level 1 to 0) for a STM32L151 (Cat.2).From my own investigation it appears that after a forced mass erase all the option byte...
I'm trying to enable the OB_RDP_Level_1 for a STM32L151CC but It fails. The MCU becomes bricked. I can't even boot to DFU. I need to first start ST link utility and set read out protection level 0, and then do a chip erase. But I noticed that bit OPT...
Hi, I’m trying to use the cryptographic library on a board based on STM32L152CBT6-A to encrypt data to be sent. I tried to replace the files inside the “Driver�? folder but it did not work. Does anyone know how to use the library and import it correc...
I am working on STM32L151QD MCU. I want to implement CRC feature in my application using STM hardware CRC block.i am trying below steps to configure HW CRC:uint32_t crc; uint32_t t_buffer[4] = {1,2,3,4}; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_CRC, ENAB...
Hello. AllI'm using STM32L151 MCU, stm32 crypto library v.3.0.0.I implemented CMAC according to the sample code but it returned "AES_ERR_BAD_CONTEXT". I could not find any reason.. please let me know to solve this problem.!!Here is my code for CMAC e...
