I have a working program on my own board using a STM32G081KBU6. Debug using SWD and programming a release version works fine. As long as RDP remains at Level 0, I'm able to debug, erase and reprogram updates to the board.Usually for other ST MCU's th...
Hello, I'm posting a new message because the previous one was not answered with successful connection. The problem is that when MCU is populated on my board with Read-Our Protection enabled, it is not possible to connect STM32CubeProgrammer v.2.21.0 ...
Hello,I'm looking for some clarification over how the PCROP area can be used. The user manual for STM32L471 states that code in this area can be executed but that data at flash in this area cannot be read. Does this mean if I put a decryption algo...
Good morning everyone,I need to apply the "Closed" product state to my device using the STM32H573VI.I don't need TrustZone enabled and want to use a password for debug authentication.I wanted to perform the operation via "code" using the HALs, but on...
I have exported X509 certificate from STM32H573I-DK board, and checked how it is organised.The certificate was issued by "ST CA 01 for STM32 Initial Attestation".I would like to verify whether it is truely signed by ST's upper-level certificate.Wher...
Hi ST team,I am using STM32U5G9 in my project. It would need simple firmware update feature and the image would be received by UART from a zigbee module.I have read UM2851 and AN5447 application notes and check the SBSFU example in STM32CubeU5 packag...
We need to develop an offline programmer to program the STM32H562VIT. The product state need to be changed to Closed with an OBK file programmed. The OBK data only in HDPL1.We can't simply use the RSS to program the OBK like STM32Cubeprogrammer. We c...
STM32 H573 TrustZone Enabled question. I'm executing the STM32 H573 example for TrustZone Enabled (OEMiROT, Secure, and Non Secure Apps). I know the OEMiROT and Non Secure App prints out and logs info, but I want to be able to do that in the Secure ...
Hello, I am looking for guidance regarding the STM32H533 MCU, specifically in the area of secure and non-secure memory management.Could you please let me know if there is a dedicated application note that explains how to store and manage encrypted ke...
Hi,I am using STM32H563 with OEMiROT_Boot example project, I got a problem to read the FLASH_SIZE register (0x08FFF80C).I found two issues,(1) the value of this register is 0 at begining of OEMiROT_Boot main() function.(2) the register become not acc...
