Posted on July 12, 2018 at 13:43Hi, I am trying to use CRYP_AES_GCM example from STM32Cube_FW_F7_V1.11.0 for stm32f769I-eval. I see, stm32f7xx_hal_cryp.c has two set of APIs. By default the APIs under ' &sharpif defined (CRYP) ' are enabled. and t...
Posted on June 23, 2018 at 08:49HelloI am using stm32l152rc controller and I am trying to load a code using a dfusedemo application and during that time my flash is on RDP level 1.With help of msp my code jump to location 0x1FF00000 which is locati...
Posted on July 03, 2018 at 10:11 Helo friends, I try calculate CRC8 in python and compare with CRC in STM And I have a problem. My python CRC is return wrong value. Python script: def AddToCRC(b, crc): b2 = b for i in xrange(8): od...
Posted on June 25, 2018 at 19:53For a customer I want to set RDP Level1 on STM32F4, and put in first sector a bootloader that manager a jump to DFU for device upgrade.I set the RDP L1 by code at init, and disable it with STMCubeProgrammer.Will the I...
Posted on February 05, 2018 at 11:12Dear All,I have some questions related to ♯?:1) How to enable ♯ for ♯ boot-loader and for user application?2) Since I was not able to find an information how to make a ♯ and remove ♯ from the MCU (STM32L476) I wo...
Posted on May 14, 2018 at 10:07Hi,Does anyone knows how the counter is handled in AES_CTR_Encrypt_Init() / AES_CTR_Encrypt_Append().I suppose it is somewhere in the IV, but the documentation does not talk about it.The examples use an IV initialised ...
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...
Posted on May 12, 2018 at 05:54My device use STM32f437VG (which supports hardware crypto) but sometimes we cannot buy it and use STM32F427VG (which NOT support hardware crypto) instead.So my program have to check if the MCU is 437 or 427 to use prop...
Posted on May 11, 2018 at 14:41Hi!I'm struggeling with hardware accelerated aes algorythim. Based on example project I've enabled CRC clock and initilzed the operation, by passing the key (AccHw_AES_CFB_Encrypt_Init(&, , )). After that I'm trying en...
