I did more debugging using OVMF and found that the i386 boot loader code was trying to call printf (which allocates memory) after ExitBootServices.

[edk2] Hang when calling ExitBootServices on IA32 firmware v1.0 on MinnowBoard Turbot
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 SetUefiImageMemoryAttributes - 0x787EB000 - 0x4000 (0x0008) SetUefiImageMemoryAttributes - 0x787E8000 - 0x3000 (0x0008) SetUefiImageMemoryAttributes - 0x787E5000 - 0x3000 (0x0008) SetUefiImageMemoryAttributes - 0x787E1000 - 0x4000 (0x0008) SetUefiImageMemoryAttributes - 0x787DB000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787D5000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787CC000 - 0x9000 (0x0008) SetUefiImageMemoryAttributes - 0x787C6000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787C3000 - 0x3000 (0x0008) SetUefiImageMemoryAttributes - 0x787BD000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787B8000 - 0x5000 (0x0008) SetUefiImageMemoryAttributes - 0x787B2000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787AC000 - 0x6000 (0x0008) SetUefiImageMemoryAttributes - 0x787A9000 - 0x3000 (0x0008) SetUefiImageMemoryAttributes - 0x787A5000 - 0x4000 (0x0008) SetUefiImageMemoryAttributes - 0x787A2000 - 0x3000 (0x0008) SetUefiImageMemoryAttributes - 0x7879F000 - 0x3000 (0x0008) 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=markup . -- Rebecca Cran ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
