Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Posted on May 12, 2018 at 19:55Secure Boot and Secure Firmware Update is just awesome. Very excited to use it. However, for whatever reason, the process of setting up and practical usage of it is quite confusing.I've loaded the demo application(s) i...
Hi everyone,I'm developing a safety project and using the STM32F446. To ensure the safety standard, before starting the main code, I need to compare the current flash CRC with the CRC which calculated with SREC. The same structure is being used in an...
I am looking for some help with the setup and use of the Cyclic Redundancy Check (CRC) unit implemented in the SPC56 family of automotive uCs; So far I could not find a single sample of code showing how to configure and use it with one of the differ...
hi, im trying to enable the readout protection and successful in doing so but my application doesn't seem to run after its enabled,after entering this function system reset occurs and my user application doesn't seem to run.HAL_FLASH_OB_Launch ()
I have been asked to find out if release STM3232CubeExpansion_CryptoV3.1.1 is the latest release of this package, and if not please tell me where I can get the updated version. If there is no update, can you tell me if and when one is expected
I have polynomial for CRC 0x8C. And in STM I must write 0x31, because it is rotate.But I don't know, how to convert this value to good value.In binary:0x8C - 0b100011000x31 - 0b00110001I create function:uint8_t ror8_polynomial(uint8_t poly, uint8_t ...
Posted on May 23, 2014 at 03:03Hi All It is strange but I can't find any code example of how to set up the Ethernet HASH filter for multicast reception. There was a question in 2011 in this forum as to the same but it was not answered - so I will tr...
Our application connects to a server in the cloud and recently we migrated from a proprietary AES256 encryption to Mbed TLS based solution.By default Mbed TLS does NOT offer out-of-the-box hardware acceleration for AES, MD5, SHA etc. By accident I wa...
Greetings, I'm building an app for an STM32L496. I am trying to get the linker to calculate a CRC32 of the ROM image and place it in ROM. I've read a few technical notes on this, and I'm following the ARM example. The problem is I keep getting ...
