Mike/others, Further info...
I've cloned https://github.com/tianocore/edk2, Downloaded the Linaro toolchain binaries, 'wget http://releases.linaro.org/13.07/components/toolchain/binaries/gcc-linaro-aarch64-linux-gnu-4.8-2013.07-1_linux.tar.xz' Unpacked them ' tar xf gcc-linaro-aarch64-linux-gnu-4.8-2013.07-1_linux.tar.xz' Set the env variable ' export AARCH64LINUXGCC_TOOLS_PATH=<path to gcc-linaro-aarch64 directory>/bin/' And used the following in Conf/target.txt ACTIVE_PLATFORM = MdeModulePkg/MdeModulePkg.dsc TARGET = DEBUG TARGET_ARCH = AARCH64 (must be caps even though the listed arch in the comment is mixed case) TOOL_CHAIN_TAG = ARMLINUXGCC If you tried building, be sure to clean the Build directory first -- I had mixed results when switching between toolschains... The first relocation is 0x0, which I believe is R_ARM_NONE (as opposed to R_AARCH64_NONE which is defined as 256). I believe this can be ignored by adding a case with a break stmt to the (e_machine == EM_AARCH64) sections. The other is 0x105 (261) or R_AARCH64_PREL32 (S + A - P) which I really have no idea how to handle. (I haven't looked at GenFW, etc. to try and figure out.) (Both of these relocations show up in you log capture.) Anyways, using the Linaro tool chain, I've build the HelloWorld.efi app and successfully run it, as well as building other driver code that (modulo hw issues), runs as expected as well. // Joseph Thomas // Principal Software Engineer // Dot Hill Systems // 2905 NorthWest Blvd., Suite 20 // Plymouth, MN 55441 // 763.226.2640 -----Original Message----- From: Brainerd, Mike [mailto:mike.brain...@amd.com] Sent: Tuesday, September 16, 2014 5:51 PM To: edk2-devel@lists.sourceforge.net Subject: Re: [edk2] EDK2 GenFw I downloaded EDK2 yesterday, 'git clone https://github.com/tianocore/edk2'.
