Thank you Andrew for this information. I set it to *true* cause the builder was asking for a *Depex section*. Setting it to *false allows QEMU* to boot properly. Nonetheless, the driver *doesn't seem to be called*... yet.
Concerning Pedro's suggestion (Olá!!!), thank you for pointing me to the DebugLib, I'll look into it. Nonetheless, I'll need to *use ConInt and ConOut in production*. I am aware of a DXE program that does it. Maybe I was passed the wrong information and the program is running on another phase... Anyhow, in theory I'd be able to install the I/O protocols in the DXE phase in order to be able to use them. Right? The *TerminalDxe.inf* , a *UEFI driver* , states: *Terminal module installs Simple Text Input(ex)/Out protocols for serial devices * I think assumed erroneously that the *OvmfX64.fdf* is setting the ordering of the DXE drivers. After Andrew's answer I realised that may actually be done in the *Depex Section?* I'll read its specification now in order to better understand how to use it. Nonetheless, I tried turning it from a *DXE_DRIVER* into a *UEFI_DRIVER* and it's still not natively being listed in EFI Shell's *drivers* command. I don't see yet how mine differs from *TerminalDxe*. Maybe it's crashing and being unloaded. Maybe it's simpler than all of this. My true goal is: my program needs to be shipped with the BIOS image in ROM and run for sure on every boot, with no possibility of being *circumvented*. I have also read that some DXE drivers are not guaranteed to run if something like fast boot is activated. Taking that in consideration, what module type should I create to achieve my goal? Finally, is there any documentation on actual programming using EDK2 ? Say, which functions can I use to read user input? Or what dependencies do I have to include as LibraryClasses if I want to use a certain function? Is reading source code the only way to go ? I have also used DoxyGen to generate docs, but it's far from ideal. Cheers, Diogo -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
