This thread discusses the Pi Zero config.txt settings for CPU etceterasvrsig wrote:The cpu speed appears to be stuck at 700MHz on RC14, even with Nov 2015 firmware and a 30-Dec-2015 RISC OS ROM image. What changes do I need to make please to config.txt to force the correct 1000MHz speed for the cpu please? Speed switching (SYS "Portable_Speed") is not implemented in the RISC OS kernel on the Pi.
