Hi Lattepanda team,

I would like to know whether LattePanda is able to switch from 32bit UEFI to 64bit? After a long research I found out that the Intel board called Minnowboard is able to do that. They have a full explaination in this wiki "http://wiki.minnowboard.org/UEFI". In their wiki it seems easy enough to switch from 32bit to 64bit. I need the 64bit to support linux future roadmap out-of-the-box where they have obselete most of the 32bit linux OS. Now just to install linux OS we need to do a lot of workaround work.

Beside that, LP team will you make a guide for Bios Recovery? In case, we brick our LP board while flashing the bios with a corrupted bios file.

Regards,
maideii

Is your LattePanda is a normal or an enhanced version? I would expect a 64-bit UEFI64 for the enhanced version. But now I wonder...

Beware of BIOS. I think I kind of reset it. While I'm not sure, it may be the cause why I cannot boot at all (devices like USB, µSD and video are not powered on) because if BIOS fails I see no reason why devices will be ready.

Mine is normal version with 32bit UEFI. Without a proper BIOS recovery guide, I am hesitate to touch the BIOS. I read many Lattepanda boards bricked in this forum just by flashing the BIOS provided by LattePanda team themselves.

For normal PC, I won't worry about bios corrupted because most of them come with bios recovery function to avoid we bricked the motherboard.

For your board if not mistaken, all the 4gb RAM board will be 64bit UEFI with 64bit windows.

Any news for this topic? I have the same question, I need to know if I can switch the UEFI from 32 to 64bit for the 2G/32GB version of the board, like the Minnowboard.
Thanks in advance, Andrea.

Dear Andrea, the latest LattePanda comes with 64bit UEFI. We've made changes for a long time. And we release 32 bit UEFI from github. Factory setting is 64 bit UEFI now...
Enjoy Tinkering with LattePanda ! :lol:
