Windows UEFI firmware update driver

NTDEV
1

Hi all,

I’m implementing device firmware update driver using Windows UEFI firmware update platform. As I understand I will need:

  1. Update ESRT table definition to public Update Firmware resources
  2. Implement UEFI Update Firmware Driver, update UEFI bootservices?
  3. Create Windows update driver package: INF, Cat, Firmware Binary file. No need to implement any code in this package.
  4. Install Update Driver package on Firmware Device and run update.
  5. Run HLK and submit HLK package.

Please correct if any wrong.

Thanks a lot.

Hi Khanh

I’m not a Windows expert but I have being working with firmware for several
years.

At a UEFI BIOS you can update parts of it.
So when you say:

“2. Implement UEFI Update Firmware Driver, update UEFI bootservices?”
Maybe you need to understand better what part of the firmware you need to
update, based on the binary you have.

Maybe you need to update a specific FV (firmware volume), maybe more.

If this system has “secure boot” this development will require some magic
too.

Anyway, this us just a tip to avoid surprises in future. Hope it can help
in some way.

Rafael Machado
