UefiOta

A minimal implementation of UEFI OTA.

UEFIUpdateServer.py

Provides a minimal HTTP server as a UEFI OTA check server.

Usage

py -3 UEFIUpdateServer.py {port}

It will show some tips like:

Server started at http://123.456.78.90:5000
Press Ctrl+C to stop the server

Open http://123.456.78.90:5000 link, then input Version and Select BIOS File, then Publish.

http://123.456.78.90:5000/update will provide OTA message and binary's link:

{"message": "New BIOS version available: 01.01", "image_url": "http://123.456.78.90:5000/BIN/BIOS.bin"}

HttpDownloadLib

Based on EDKII ShellPkg HttpApp, and modify it to a Library to provide HttpDownloadFile() API.

TestApp

UEFI Shell application to test UEFIUpdateServer.py and HttpDownloadLib.

UEFI BIOS SETUP

Add one button in .VFR like:

    text
      help   = STRING_TOKEN(STR_UEFI_OTA),
      text   = STRING_TOKEN(STR_UEFI_OTA),
      flags  = INTERACTIVE,
      key    = 0x1024;

Call BiosUpdateCheckHttp(TestApp) in HiiConfigAccess.Callback. (You need to add some code to call UEFI BIOS Update function)

Notes

1. The firmware needs to include the UEFI network stack module
2. At lease one NIC
3. Make sure the driver is connected before calling HttpDownloadFile() API
4. Connect the network cable and ensure that the http server is normal

TODO

• HttpDownloadLib download speed
• HTTPS?
• JSON Parser?
