Is there a walk-through or example of how to setup secure boot using a custom device tree?As a side note, the following page returns "Permission Error", is that expected behaviour?https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot
Resolved! File handling functions (fread, fwrite, getc, fseek, etc.) do not work in the STM32MP15x Cortex A7 core. Why is that and is there a solution for it?
Hello,When I tried using fseek and getc functions for my project the MP1 failed to execute their code. The execution stops at lines that contain __IO_acquire_lock(fp) and __IO_need_lock(fp) macros and then terminates in the fseek and getc functions r...
