What is the correct procedure to replace the example UserApp in SBSFU with a different existing project in STM32CubeIDE (generated with CubeMX)?

I have attempted the following:-Build and tested a simple app, called TestApp with STM32CubeIDE/CubeMX, runs fine on itself (without SBSFU)-Build and tested the SBSFU 2_images example, works fine.-The TestApp runs on the same hardware as the SBSFU ex...

what is the FIPS certification available for X-CUBE-CRYPTOLIB ?? I see NIST-CAVP Certification which is FIPS 186, what is the difference from FIPS 140-2/140-3 complaint. is both are same ?

We are looking for FIPS 140-2 / 140-3 certified Secure Boot loader implemented with help of X-CUBE-CRYPT LIB for STM32H753VI MCU.if i see NIST-CAVP certification, it is mentioned as STM32L4 series, then is thios same certificate is applicable for STM...

I am working on RDP programming on STM32U575 . My query is how can i perform RDP 2 to RDP 1 regression(or RDP 1 to RDP 0) using OEM keys in my firmware ?

I found an application note for regression of RDP level using OEM keys via STM cube CLI .But my use case is to do it by firmware .Can it be done ?/Jaroslav HOUDEK​  @zqizh.1​ 

Why interrupts not occur under debug when RDP switched to level 1?

WIth oocd I try to do following steps:1) Send reset and halt command2) disable bit DHCSR.C_MASKINTS3) Enable interrupts into ISER reg4) Make any interrupt pending in ISPR reg5) Perform Step commandif readout protection is diasabled, core interrupt oc...

I want to start the update out of my application as the UserApp does. I have ported the functions but I'm searching for the definition of SlotEndAdd and SlotStartAdd. They are defined as external in sfu_fwimg_regions.h.
