Good evening,I requested the download for XSBSFU package last week , but never received a conformation Email. Today I made another one request and got a conformation Email. I read that it might take up to 48h to get the link, which would be to late f...
Hi... there Hope all are doing well From past few days I'm playing with SBSFU with STM32 L4 Cell-01 Discovery board I'm using x-cube AWS default application with default settings of the linker fileIn demo code, I've added SDMMC with FAT fs, which is ...
Hi!I requested the download on Saturday (sorry - I missed the first mail regarding the setup and was'nt aware of the delay in granting download permission...I started the setup late on Saturday) - I read that it might take up to 48h to get the link, ...
Hi all,i watched the webinar: STM32CubeIDE for STM32L5 microcontroller and there is one question left:We have two independet projects for the secure and the non secure code. The gateway code that is provided to call secure functions from the non secu...
Today when I generated CRC from output binary file I found it did not equal the data in the board. Then I check the data in board , I found the data which loaded by stm32CudeIDE was padding with 0xFF, but the stm32CudbeIDE generate the binary file wi...
Hi, We are using SPSGRF-868 module in our project, With following settings of RF module operating @868 MHz Send/receive data without Encryption we are able to achieve 20~25 meter distance and working fine. But Send/Receive the data with encryptio...
I've developed an IOT device and now I'm concerned about security. Uses ethernet, tls and mqtt to upload cloud data. Checks a directory on the web for firmware updates. The mqtt is well sanitized and i'm not extremely worried about attack vectors com...
Please check attached Source code file with complete test code.I am using STM32WB55xx with algorithm : RSA/PKCS#1v15/rsa_pkcs1v15.h Note - Public key is 2048 bitIssue - If we set following modulus(publicModulus[2048 / 8] ) not getting any result/sta...
Hi, I hope the day is going well for everyone.We've been working to validate SHA256 computations on the HASH unit of the board named in the question. In the process we have noted what appears to be a reproducible problem with the unit.In short it ap...
