Hi @实在太懒于是不想取名 , I have yet to create the step-by-step instructions for the secure and non-secure applications, but you can use the available template to compare with your code or use it as the starting point for your application. the Template is thi...

Hi @asdfasdf , I've checked the board and chip review, you have the rev. B, which is the latest one so you are good on that portion, but checking the OTP dump, this one caught my attention: BOOTROM_CONFIG_1 | OTP10 | 0x00030103 The bits 16 and 17 set...

Hi @exarian , thanks for the feedback! Please see my comments below: Q1: Do you have an example that checks the integrity of the Appli signature on the FSBL? C1: Currently we don't have any examples to cover that portion without using the Secure fram...
