Inserting Modules into LattePanda BIOS
One advantage of UEFI is its modularity, meaning you can write a module that, once compiled, can be inserted into an existing BIOS and executed. Previously, the implementation methods of each IBV varied greatly, and there was almost no way to achieve universality except for inserting in a special form like PCI ROM. The demonstration here is to write a DXE module in the EDK2 environment and then insert it into LattePanda.
First, design the code, and you can write it
