Hello all,Kindly guide us how to resolve the following issue or share the sample code,We are using MCU STM32U585QII6QTR. In this TrustZone is not enabled.We are trying to change the RDP level from 0 to level 1 and from level 1 to level 0 from softwar...
Hi,I need to implement things that are required to implement secure boot & secure software update STM32 H733 Microcontrollers. Trying to understand from the beginner perspective, though I have the Cube package downloaded from the st website, still li...
Hello,I have a setup with two partitions (active + download) and a user application that also acts as a firmware loader.At the moment, the loader/user application downloads the new firmware to the download slot successfully and after reset the new fi...
Hello,I use STM32WLE5 on a seed studio module LORA-E5 mini where boot0 is not accessible (completely crazy ...). The module comes with a read protection and they ask us to remove RDP (level 1 to level 0) to be able to flash it with a custom program. ...
Hello,I'm currently working on a project that involves using the SFBU (Secure Firmware Bootloader Update) due to the limited flash size of the MCU. I've set up an external EEPROM to store the entire firmware before the update process.I've made necess...
Hi, I am looking for some API which supports chain of certificate feature for NetxSecure TLS, Just like mbedtls_ssl_conf_ca_chain() API in MbedTLS.Need help. Thanks in advance.
