Hello, I have a simple application running on STM32L55 Secure World, but I would like to debug it step by step using an IDE.I am able to debug using the Keil IDE, but it seems the TZEN bit is zero. It must be about the defaults state of the STM32L55 ...
Hi all,I’m trying to find out when the Boot Hardware Key (BHK) is exactly written and locked (using the B-U585I-IOT02A discovery kit).The reference manual (RM0456, page 1513) just says that it is „written by a secure code during boot“.So I modified a...
I am able to run "2-Image" sample application in NUCLEO-L073RZ board.I would like to use "1-image" application due to memory restriction.But example application for "1-image" is not provided for NUCLEO-L073RZ board.Could you please let me know the ch...
I am using STM32L562E-DK for my development. I have ported SBSFU for it. I want to add watchdog functionality to it. Currently, I am initializing the watchdog (window) from the application and feeding it from Freerto's task in the application.Now, I ...
Hello,I am trying to get familiar with X-CUBE-SBSFU. I am currently confused about the meaning of "-v, --version" flag for "prepareimage.py header" and "prepareimage.py pack" commands, e.g. from readme:python prepareimage.py pack -k OEM_KEY_COMPANY1...
Hello guys, how are you all?I'm currently developing using the X-NUCLE-SAFEA1 board integrated with an STM32WB55. I was executing the pairing example generating a randomic mac and cipher key. I stored successfully this keys into the STSafe, but my pr...
The datasheet on STSAFE-A110 seems to clearly state that the chip provides symmetric encryption services, however the Cube expansion package and middleware in there does not appear to support that. Where can I get the examples of using this feature?
Hello,I am trying to generate the combined elf file with SBSFU and user app. The provided postbuild scripts use the following code to create the file:command=$programmertool" -ms "$elf" "$headerbin" "$sbsfuelfThere is a problem that the combined elf ...
