  • Hi,

    no, there should not be a difference in speed between the regular J-Link and a J-Link EDU.
    In general, J-Link EDU is fully compatible to the regular J-Link, but may NOT be used to develop a product.

    Terms of use:

    You may use the J-Link EDU for non profit educational purposes only. Non-profit educational purposes means that you may not use the J-Link EDU and its J-Link software

    * direct or indirect in or for a profit organization or business purposes or other undertaking intended for profit
    * direct or indirect in any other commercial environment (e.g. office)
    * to develop, debug, program or manufacturer a commercial product (or parts thereof)
    * to use it to either earn money or reasonably anticipate the receipt of monetary gain from it.


    Best regards
    Alex

    I am use J LINK EDU for educational purposes only, for porting Linux on my Pocket PC device.

    Speed test of memory dump:
    Wiggler jtag(self assembled): 25 kbytes/s
    jlink edu: 12 kbytes/s

    This result am not expected :)
  • Hi,

    In your original post you wrote:
    There are exist difference in speed for J-LINK EDU and for J-LINK


    Did you also test it with a J-Link? Ist the J-Link EDU slower?
    Which JTAG speed did you use when performing the memory read?
    Which CPU do you use? (Core, Chip name, Chip manufacturer).
