Hi @xiang_1001
Based on your output, the multicore demo on the i.MX93 EVK is actually working correctly, despite the error message.
error -2 = ENOENT (No such file or directory). This is not fatal.
The kernel first tries to load the firmware using the default firmware loader mechanism (usually from /lib/firmware).
Since your firmware is in a custom path (/examples/...), it fails the default method.
Then it falls back to sysfs, which is exactly what you intended by writing the path to /sys/.../firmware.
Finally, it successfully boots the CM33 core with your ELF file.
So you don't need to fix anything.

Daniel
