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...
Hi ST community,I have a fully functional application on my STM32L072. The problem is when I tried to enable RDP, nothing works anymore.After flashing the application I tried to connect with ST-Link, the option bytes are set correctly and it is not p...

Read Protection has been set in the STM32 chip .In this case, how to judge the chip is in the read protection state through the bootloader program of the chip.I now is to send the erase instruction, if return NACK, judge chip is in the read Protectio...
