HSE Secure Boot

[Temple]

Hi all:

I would like to ask a question to you.

After I configured BOOT_SEQ = 1 using function HseMid_SecureBoot_EnableSeq(as shown in the figure above), and then powered on the device again, when I read the chip memory, I found that BOOT_SEQ was not set to 1.

How to keep BOOT_SEQ as 1 and make sure that my secure boot will get start？

Thank you for your reading.

Hi @Temple 

Does function HseMid_SecureBoot_EnableSeq really update Boot Configuration Word? I guess there's something wrong in the function. The BCW can be changed back to 0 only by next reprogramming, it's definitely not done by MCU itself.
