The current tools are hoisted on github. https://github.com/foss-for-synopsys-dwc-arc-processors/ You could use upstream buildroot which automatically picks up relevant tools branches from our github repos. Please note that ARC cores are based off two ISA: ARCompact and recently announced ARCv2. Thus it would be awesome if we could build following kernel configs on regular basis: - axs101_defconfig - axs103_smp_defconfig This however needs 2 toolchain installs as we don't have multilibed tools which support both ISA. You can do following to generate the tools (this first pass builds the kernel as well which can be disabled if u so wish). $ wget http://buildroot.uclibc.org/downloads/buildroot-2015.08.1.tar.gz $ tar -xvf buildroot-2015.08.1.tar.gz $ cd buildroot-2015.08.1; mkdir arcv2 arcomp $ make O=arcv2 snps_axs103_defconfig ; cd arcv2; make ; cd .. # for ARCv2 tools $ make O=arcomp snps_axs101_defconfig ; cd arcomp; make # for ARCompact tools There's another way to build them by hand - with finer grainer control of specific tools branches, target flags and so forth. Let me know if you prefer that and I can point you to same (they in toolchain repo on github) Many thx for looking into this. Please let me know if you run into any issues with above. -Vineet -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
