Subject: Hang when calling ExitBootServices on IA32 firmware v1.0 on MinnowBoard Turbot
Date: Mon, 25 Feb 2019 17:08:33 -0700 [thread overview]
Message-ID: <794b312c-44bf-f482-4933-e8fbb2a48c74@bluestop.org> (raw)
I've been trying to test a boot loader on my MinnowBoard Turbot board.
It's running the latest 1.0 firmware from firmware.intel.com, and I'm
seeing a hang at the point when gBS->ExitBootServices is called.
The last debug output is:
ConfigSccBootableDevicesAtExitBootService() End

The X64 firmware works fine: the boot loader finishes and the kernel
starts running.
I looked to see where ConfigSccBootableDevicesAtExitBootService might
be, and unfortunately it seems it's in one of the binary modules.
The code for the boot loader is in
https://svnweb.freebsd.org/base/head/stand/efi/loader/bootinfo.c?revision=338022&view=markup
.
