Okay, I hadn't been thinking in those terms because in my mind I already had the sdcard 'allocated'. That is useful. Bricking GlobalScale units is definitely a thing... I managed to do it to one of there Guru boxes back in 2012. Never had time to fix it; at those prices it was cheaper to bin it than have them pay me to figure it out!
As to the development, I can do both. I have a full set of the packages for the release on the Miraboxes (7.1) ... it is an old release but they have stayed with it for years and but for the kernel it serves my purposes. I have one of the test units designated as the development system for my own debian packages anyway and I've already got gcc and all of the debian helper package tool chain on it. Also, I have several 256 GB USB 3.0 sticks laying around my lab bench, so no problem. I am really glad to hear that cross compilers have been simplified. Walking 10 miles to school in deep snow, up hill both ways, is best left in the past. I'm hoping to come out of this with a simple, replicable install sequence using the newly built kernel and module set... I will have to replicate this on at least 4 other units. It would also be nice if I can breath life into 4 old units I have and be able to describe the process to a couple of folks who work with me remotely on occasion so they can upgrade as well. -- +---------------------------------------------------------------+ | Dale Amon Immortal Data | | CEO Midland International Air and Space Port | | a...@vnl.com "Data Systems for Deep Space and Time" | +---------------------------------------------------------------+
