I also offered a patch to the BaseTools project to fix the firmware when linked at 0x0 in the past. But my patch has been rejected and a new keyword has been introduced to fix this BaseTools limitation.
In your Versatile Express A5 FDF file you have to replace:
[FV.FVMAIN_SEC] FvAlignment = 8
By: [FV.FVMAIN_SEC] FvBaseAddress = 0x0 FvForceRebase = TRUE FvAlignment = 8
-----Original Message----- From: boot-architecture-bounces@lists.linaro.org [mailto:boot- architecture-bounces@lists.linaro.org] On Behalf Of Ryan Harkin Sent: 21 June 2013 08:44 To: ryan.harkin@linaro.org; edk2-devel@lists.sourceforge.net; edk2- buildtools-devel@lists.sourceforge.net; patches@linaro.org; boot- architecture@lists.linaro.org Subject: [PATCH 1/1] BaseTools: Apply ARM GenFv patch
This patch is needed to fixup some builds, such as Versatile Express A5, otherwise they hang on boot due to the first instruction being zero.
