Pre-encrypted firmware do not work on QEMU (QEMU-159)

Hello,

I tried to burn eFuses and firmware on both QEMU and physical chip (ESP ECO V3). Encrypted flash + Secure Boot v2

It is working ok on physical chip but not working on QEMU.

Generating eFuse bin with MAC and version bits set: gen_efuse.py qemu_efuse-mac.bin

Running QEMU in strapped mode:

    -machine esp32 \
    -drive file=qemu_flash_image.bin,if=mtd,format=raw \        
    -global driver=esp32.gpio,property=strap_mode,value=0x0f \
    -drive file=qemu_efuse-mac.bin,if=none,format=raw,id=efuse \
    -serial tcp::5555,server,nowait

Programming eFuses by the same script I use to program physical device, the only port changes. ... (Everything goes smooth, eFuse settings checked after burning)

Running QEMU in app mode:

build/qemu-system-xtensa -nographic \
    -machine esp32 \
   -drive file=qemu_flash_image.bin,if=mtd,format=raw \
   -drive file=qemu_efuse-mac.bin,if=none,format=raw,id=refuse

This gives me an error:

The message repeats once per 4 seconds. CPU load is 100%. Host System: MacBook M2 (Apple silicon)

Any ideas?
