I am using an STM32H757. I understand how, using the TrustedPackageCreator and an HSM, I can supply our manufactures with an encrypted version of the firmware and limit the number of product instances they can produce. My question is, when the produc...
Hello,I am trying yo implement the HW encryption acceleration on a STM32F423CH for AED CCM Mode. I tried to implement on the first place the CTR encryption mode but it seems to me that the example provided in the NIST Special Publication 800-38A cann...
Hello,I am trying to flashing SBSFU application on the STM32H7B3I-DK board using STM32Cube Programmer. I am using STM32H7B3I-DK 1_Image example project from SRM32CubeExpansion_SBSFU_V2.6.1. The board is working fine in the first boot and all the jump...
Hi,I have a chip marked as STM32F437 but my software fails on running the SHA256 algorithm on the hardware crypto module.The only difference to the STM32F427 is the additional presence of a hardware crypto accelerator in the STM32F437.How can I check...
I shall just write a function in software but I would be interested to know if it is supported or not by the CRC peripheral hardware.STM32 cube MX configurator does not allow you to choose X7 for the 7bit (8 term) polynomial described on page 21 of t...
I have decided to try out the X-Cube-SbSfu, i have downloaded the SW from the ST website,according to the documents available this is an expansion pack that can be added to the CubeMX.is this correct?where can I find information about the process tha...
I have worked with the HAL software implementation of the CRC using HAL_CRC_Calculate() and HAL_CRC_Accumulate(). Works great. How do I utilize the hardware CRC feature? Can you direct me to an example or more information?
Hello,I am trying to port SBSFU example project on STM32L433RC board. I followed getting started and integration guide to integrate STM32L432KC SBSFU 1 image example project(after modification) on STM32L433RC board. Below is the image where it gets s...
