Resolved! debugging with a different hex file?
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

Is it possible to use the STM32 Cryptographic library on a ECOM10?
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...
Resolved! CRC calculation using srec_cat
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...

Software CRC with a polynomial length of 8 and 16 bits
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...
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...
How does the STM32 bxCAN HAL module calculate the transmitted and check the received 15-bit CRC field? What is the generating polynomial?
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.
Resolved! Calculate CRC-8
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
Resolved! Board does not boot after readout protection enabled.
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?
Stm32 options bytes get randomly reprogrammed even when flash not unlocked
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...
