    Hi ! 

    I boot my Windows Ce 6.0 with lboot.lol

    In lboot.lol have next code 

    mount yaffs /dev/nand0 /YaffsPart1

    video-open 15 16

    load bin /YaffsPart1/NK.bin 

    exec 

     I want to change(decrease) cpu-freq. I wrote  

    cpu-freq low 

    In standard development kit booting  is ok .But in my device  when I decrease cpu-freq , I saw next log in Tera Term :

    losh> mount yaffs /dev/nand0 /YaffsPart1
    YAFFS core: yaffs: Mounting YaffsPart1
    YAFFS core: yaffs: restored from checkpoint
    losh> cpu-freq low
    Dynamic control: on
    Core voltage: 962 mV
    Core clock frequency: 300 MHz
    losh> load bin /YaffsPart1/NK_v2.bin

     ** OALCacheGlobalsInit g_dwRangeLimit=0x40000

    Do you have any idea about cpu-freq ? Maybe about power managment or OAL . I am prepare to check all cases.

    Thanx a lot !

    I am not sure understand you question. You can change the CPU frequency in Logic Loader, but WinCE its own power management system, so when WinCE boots, it will control the speed. Can you give me more background on what you are trying to do?
