imx93 test hello_world application

I'm testing the hello_world application as documented, but I get an error. What's the cause?

Could you please the BSP /SDK version you are using ?

Regard

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.
