I also confirmed the problem. ( I was using old source. :) Bogo Mips and calibration infomation are incorrect. UART is not used for its calculation. It seems there are problems with the timer or interrupt controller. <case 1> 100MHz: "-global milkymist-sysctl.frequency=100000000" root:/proc> cat cpuinfo CPU: lm32 MMU: none FPU: none Clocking: 277.3MHz BogoMips: 3879.73 Calibration: 1939865600 loops root:/proc> <case 2> 10MHz: "-global milkymist-sysctl.frequency=10000000" root:/> cd /proc root:/proc> cat cpuinfo CPU: lm32 MMU: none FPU: none Clocking: 310.1MHz BogoMips: 3932.16 Calibration: 1966080000 loops ---------- Takeshi _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkym...@freenode Webchat: www.milkymist.org/irc.html Wiki: www.milkymist.org/wiki
