Hi @xinmeng_wit ,so what you are looking for is to minimize time between wakeup and the code execution.Try putting GPIO signal as the first thing in the main(). Enable GPIO clock, put corresponding MODER to 01 and write ODR of that pin. This way I ea...
Hi @xinmeng_wit, I just tested the shutdown wakeup with EXTI GPIO pulses with length of 35 us and it works correctly. Could you please let us know from where this 70ms in your request comes from?purple is the tamper pin pulse to wake
Hello @Shizu_T ,yes. The Secure Manager is essentially just a closed-source implementation of the TF-M, with security certifications to prove it's done correctly. By working with TF-M directly, the development will be more labor intensive and you wil...
Hello @Shizu_T ,sorry, I learned that the SM does not work with memory mapping that supports the EDATA. It's however still possible to use secure boot, iRoT and TF-M, it will only be more complex to set up than just a secure manager configuration.Br,...
