How build example project for NUCLEO-L476RG on macOS Big Sur?
I am working through the Security MOOC and in section 6, they show how to build the NUCLEO-L476RG example project on Windows. Their procedure does not work for me on MacOS Big Sur.The most pressing problem is that when I try to build SECoreBin, I get...
Resolved! API docs for CryptoLib package en.STM32CubeExpansion_Crypto_v4.0.1
HI, I am trying to port one of ST's security hands on labs for firmware protection that targeted v3.1.3 of the CryptoLib package, to v4.0.1 of the CryptoLib package. It seems like the "legacy" v3.1.3 interfaces for SHA256_Init() / Append() / and Fini...
Reducing SBSFU binary size
My user application firmware is rather big. It runs on STM32G070, so I've adapted the example code from STM32G071. I've followed the example provided in AN5056 (see picture) to reduce the SBSFU size, it saved about 10 kB, but it is not enough (still ...
Resolved! Starting Point advice for STM32L451 Cryptographic Peripheral
Hi all,I would like to use the Cryptographic peripheral in my STM32L451 to encode and decode some data based on a pre-stored common key.Are there any examples for Atollic that would get me started on this?
Resolved! STM32L5 secure access to non-secure flash block read as zero. Is it an architecturally specified behavior or just an MCU specific behavior?
I am currently experimenting on stm32l562e-dk board, and I discovered that, in the secure world, non-secure flash cannot be read via a secure memory region (i.e. not covered by any of the SAU regions). To be specific, value of zero is read.I am wond...
Huge user application binary file
Hello everyoneSo I've managed to build MY user app, where a lot of things programmed alongside sbsfu support.But the binary file is simply huge - 134 MB! How comes?Also, sfb file does not get generated. May it be connected to disabled security define...
Resolved! STM32L496 header missing Hash peripheral definitions
It looks like STM32L496xx.h does not have the hash peripheral definitions in it. e.g. The STM32Cube_FW_L4_V1.16.0 examples for STM32L496 HASH peripheral are all configured to use the STM32L4A6xx. Does ST have a plan to update STM32L496xx.h?, or Is...
Is it possible to change RDP level 2 back to level 1 or level 0?
Hi，All.First of all, LET me tell you the background of the problem. I use STM32G0 series MCU. The SWD port will be hardware connected to one of my wireless communication modules for OTA upgrade function. Then I tried to use the read protection fun...
Terminal Connection to COM port for STM Security MOOC part 4
Hi, I'm in the process of going through the labs in part 4 of the ST Security MOOCs, specifically the hands on over here .https://www.youtube.com/watch?v=0CVplWZ8zls&list=PLnMKNibPkDnF0wt-ZI74SflnsBV4yKzkO&index=3The hands on asks to connect a termin...
