Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using th...

Hello,There is a typo in Table 14 in page 153. It is mentioned in different places that STM32H7B0 supports OTP but in this table it is not mentioned!Could you please confirm that this variant supports OTP?Thanks,Ayoub

Hi,Can you please elaborate more? How it is not working? Does it show hard fault? What does this function do USB_FW_Update_Process?

There is no way that a file is changed by a tool! As I said before, you need to check which section ends at 0x800017C and use ALIGN to make sure it fits there!

I recommend to set the VTOR in the main of application before you re-enable the interrupts.

So you have SysTick interrupt priority set to 0 and all others > 1? can you please make a screenshot of your NVIC config?

Hi,Can you try lower the SysTick priority to 0 and other to > 1? That might work as it works for me!Ayoub
