Booting up Intel-core2-32 on 64-bit UEFI

[njavro]

Hi,

So I have have followed the README tutorial and was able to successfully build Yocto image with respective Intel BSP.
Initially I built Intel-corei7-64 BSP, flashed it onto a USB stick and booted it up successfully on my machine. To note, my machine is using 64-bit UEFI firmware. However, when I did the same for Intel-core2-32 I am not able to boot at all even though the Yocto build was also successful.

In order to mitigate the issue of Intel-core2-32 having bootia32.efi I have copied bootx64.efi from Intel-corei7-64 image.
That gave me small progress as I was finally able to see boot menu, however after pressing "boot" all I get is the following message: "Failed to execute boot (\bzImage): Unsupported"

I was looking through various documentation and online references to no success. Since Intel-corei7-64 boots fine, and since machine is using 64-bit UEFI I assume the issue arises from trying to boot 32-bit Yocto on 64-bit UEFI.

In current situation I assume 32-bit Yocto bzImage is unsupported by bootx64.efi, however bootia32.efi doesn't even showcase the boot menu but just gets overlooked for second boot option.

I would kindly appreciate if any tips or advices for related issue could be provided.

Thank you!

I don't have an answer to your question, but I'm curious -- why do you want to use a 32-bit image?

The world is moving to 64-bit, so this path will be less and less supported as time goes on.
