Hello, there,I need CRC8 in my design. Thinking with the Polynomial programmability in Stm32G4 . It should be straight forward.When I tried to test with the example "CRC_UserDefinedPolynomial" coming with stm32cube_fw_g4_v130 in "Examples_LL" folder,...
Hi,According to the document "AN5056-Integration guide for the X-CUBE-SBSFUSTM32Cube Expansion Package" Table 3. SBSFU code size reduction,In project "NUCLEO-G071RB", I build "1_Image_SECoreBin" by modify SECBOOT_CRYPTO_SCHEME from "SECBOOT_ECCDSA_WI...
I am using STM32F0 , F1 , F4 series of MCU now i want to apply encryption for protecting my firmware so i want to know which encryption is best for this purpose?
I am trying to build SBSFU V2.3.0 on STM32L496G-DISCOVERY board. I can build SeCoreBin and SBSFU. Flashed into board. All fine and it comes up over serial usb. However I am having trouble building the user app to exercise flashing. I am build...
I have filled request form for X-Cube-SBSFU software. Later I get the download link.When I clicked the download link first I login with my account. There were not a downloda link in that page It seams Validating One day later When I login again Valid...
I would like to extend the GCM example in STM32CubeExpansion_Crypto_V3.1.0 to be able to encrypt messages over a wired bus. Every message should contain an authentication. So the encryption of every message begins with AES_GCM_Encrypt_Init, and ends ...
I build Projects "NUCLEO-G071RB" in X-CUBE-SBSFU and load "SBSFU.bin" into the board.After reset the board, I download firmware "UserApp.sfb" with SecureCRT by using menu "Transfer > Send Ymodem" , but it failed.I also try to use "Tera Term", it dow...
Hi,I am working on stm32wb55 NUCLEO Board.I run sbsfu default code and userapp run correctly.Now i replace userapp with my customize app with few feature enable and it's working fine.If i add further features(additional code) it hang after printing b...
