Due to cost constraints, only STM32G431x8 (64K byte flash memory) can be used, but there is no sample source code for G431x8 in the SBSFU library. I tried to port such a project, but I was a little confused.1. The compilation of the 1_Image_SBSFU pro...
I am genreating a hex file from .elf in post, and adding crc to it. Is there any way to debug using new hex, in cubeide 1.1.0
Hi, I'm new in the forum and I would like to have your technical support. Unfortunately regarding this topic I was not able to found info in internet, and I don't know if I'm trying to do something not allowed by the ST libraries.For my application I...
I am using STM32F207. The project that im working on will later on will be used by a bootloader. I am, therefore, trying to add crc information in the hex file so that bootloader will be able to validate its correctness.I am using srec_cat to calcula...
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?
