Hi,I'm using a STM32H743II.The product will communicate to server using the LwIP (TCP Layer) + MbedTLS (SSL/TLS Layer), running over FreeRTOS environment.We want to use the latest TLS protocol standard (TLS Version 1.3).We are currently using MbedTLS...
Hello @Jocelyn RICARD , @D.Botelho I am trying to enable debug authentication on a stm32h573 mcu following this example: https://community.st.com/t5/stm32-mcus/how-to-enable-rdp-like-product-state-flash-protection-in-stm32h5/ta-p/708082.I was able to...
Hello!I am trying to provision a DA certificate on STM32H563 through CANFD Bootloader in system memory.I am calling special function 0x83 as described in AN2606 and AN5405. As I can understand, this is an RSSLIB_PFUNC->DataProvisioning.I am filling t...
Hello,I have two applications: one at 0x08000000 and one at 0x08080000. Both run fine individually (when setting the boot config bytes to the fitting offset). Now I want to use the one at 0x08000000 as secure area and escape it by using exitSecureAre...

There are several peripherals that have a separate layer of protection based on privileged/unprivileged, here are some examples from the reference manual:MCE:39.2 MCE main features"AHB configuration port, privileged aware"RTC:49.2 RTC main features"A...
Hi, I’m working on porting TF-M to a custom hardware platform based on the STM32U545 running Zephyr. As a starting point, I copied the existing b_u585_iot02a platform and adjusted it for the STM32U545’s 512 KB Flash. However, I haven’t been able to g...
Hi everyone!In our project for stm32f446, we are trying to use X-CUBE-CRYPTOLIB to verify the firmware signature on the device using ED25519. Unfortunately, when trying to call the cmox_eddsa_verify method, we get the CMOX_ECC_ERR_MEMORY_FAIL error. ...
Hi Team,Firmware file are just signed not encrypted through STM32 SigningTool - stm32mcu (STM32_SigningTool_CLI.exe) after generating public and private keys through STM32_KeyGen_CLI.exe.Public key in raw 64 bytes is provided to bootloader_main.c as ...
