--xPLL5cPndR2UZ7Mw Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, I've been working on adding support for embedded systems to the release scripts, which set up a chroot to ensure a clean build environment, then runs Tim's Crochet scripts. For the RPI-B, recent updates to the build scripts work fine for 11.0-CURRENT and 10.0-STABLE. However, 10.0-RELEASE images fail to boot. I showed output from 'uname -pm' out-of-band of an 11.0-CURRENT image, and was suspicious that the output showed 'arm arm', not 'arm armv6'. Warner had the same impression it should be 'arm armv6'. Hiren poked around the Crochet code, and saw that 'TARGET_ARCH=arm' is set for the RaspberryPi board by default. As a "just in case" experiment, I retried the 10.0-RELEASE code (release/10.0.0/) with TARGET_ARCH=armv6, and sure enough, it works. But, I don't know *why*. Is this a change between head/ and stable/10/ versus releng/10.0/ ? I can handle a differentiation between the branches with regard to this (sort of), but I want to make sure the correct TARGET_ARCH is being set across the different branches, so it can be handled properly in the build scripts, and usable images can be produced. So, what should be used? And where?
