I tried to step-by-step execution based on UM2262. But I could not get SBSFU welcome screen display (Fig24). My SBSFU display below.[SBOOT] Flash Configuration KO: Dual bank mode activated. STOP![SBOOT] Security issue: execution stopped!My step-by-st...
Hello, does anyone know how to programmatically calculate a CRC with a polynomial length of 8 and 16 bits? The algorithm described in AN4187 only works with a 32-bit polynomial. Here are the results:IN_REVERSE_NONE, OUT_REVERSE_NONE, POLY_32B - 0xe8b...
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...
I am trying to connect with an Intel Cyclone IV FPGA. I have looked in the reference manual for the STM, however, there is no information about the calculation of CRC 15-bit frame.
Hello,I need to know how to calculate CRC-8 of input data.I have a binary stream like (12586966 Dec or 0XC00FD6) and CRC-8(22 DEC, 0x16). Based on 0x97 polynomial how I can calculate my input binary stream CRC-8?Thanks
I have a project based on an Stm32F767. If I load the hex file and then manually enable readout protection to level 1 with the STLinkV2 utility, the board fails to begin to execute code after reset. Why? What is the correct way to use this feature?
I have a strange issue with my Stm32F767 project. We've seen with some boards randomly RDP will be enable to level 1, and BOOT0/1 are set to 0xffff. ESD seems like a potentially likely cause, but is there really enough energy in an ESD event to cause...
With STM32CubeProgrammer, I download a .hex file to my target, and it runs.Then I go to the "OB" Tab, select "BB" (Level 1) and press "Apply". After this the target does no longer run, also not after a power cycle. To make it working again, I first ...
Hello,I'm new to stm32 ecosystem and I'm trying to make in place secure boot and secure firmware update on stm32l5 discovery kit. After these two things, I would like to call secure services from non secure application via PSA API. I first get the s...
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...
