    Hi
    I want to know is any way to find out PLL or CPU clock speed(for ARM processor LPC17XX series) with J-Link [img]http://www.edaboard.com/images/smilies/icon_eek.gif[/img](Except seeing related register and calculating).
    thanks

  • Hi,

    1. Start J-Link Commander
    2. Type "device LPC1768"
    3. Type "testcspeed 0x10000000" (Syntax: testcspeed <RAMAddr>
    4. retrieve CPU clock speed.

    This option is available for most devices.


    Best regards
    Alex
