ARM / x86_64 – A More Recent Cross-Compiler..

Adventures With Linux ™ Posted on by

I had been using the armv7hl-mandriva-linux-gnueabi- cross-compiler, but that gcc version is a bit out-of-date now (version 4.6.1). I found a more recent version, for Fedora, here:  http://rpmfind.net//linux/RPM/fedora/updates/testing/21/x86_64/g/gcc-arm-linux-gnu-4.9.2-3.fc21.x86_64.html Using yum, this will also install binutils-arm-linux-gnu-2.25-3.fc21.x86_64 and cross-gcc-common-4.9.2-3.fc21.noarch and cross-binutils-common-2.25-3.fc21.noarch, to prvide the rest of the cross-compile environment. It should be noted that this is only suitable for … Continue reading →

ARM – DreamPlug to Kernel 4.0-rc1..

Adventures With Linux ™ Posted on by

Now that the DreamPlug has a stable power supply (see previous post..) I decided to live dangerously and update the u-boot version and install a modern ‘device tree’ plus kernel.. It has been mentioned many times before that the u-boot update for a DreamPlug is fraught, and can result in a ‘brick’..   There should be a way … Continue reading →

I finally got my old DreamPlug working again, but found that the power would fail intermittently..    After checking for software faults, I tracked the problem down to the power supply cable ‘clip-on’ connector..   The problem was caused by the internal connection between the two external pins and the internal slide-on metal tabs being loose, and causing … Continue reading →
