M5StickV: V-training not works

[bobitto123]

Hi, i'm trying to boot M5StickV following the steps of this page (https://docs.m5stack.com/en/related_documents/v-training), but when i insert the sd-card and turn on the StickV, the screen not show the display Training, moreover if i try to run the boot.py code on MaixPy IDE i get: "error: cannot find start.jpg", even if i insert the required files in the sd.
Thank you for help.
