ARM – Pi to 4.0.. Patience is a Virtue..?

ARM – DreamPlug Kernel Compile – Correction..

Adventures With Linux ™ Posted on March 29, 2015 by RGMarch 29, 2015

Thanks are due to Marcus Roeder, who pointed out an error in my DreamPlug kernel compile workflow (http://rglinuxtech.com/?p=1354).. The make LOADADDR.. command was incorrect, and would result in less system memory being available.. The correct command is: make LOADADDR=000008000 uImage – and this will result in all the memory being available: # free total used free shared … Continue reading →
