  • JTAGLoad frequency set and SDR command errors

    Hi,

    I'm using JTAGLoad tool to open svf file.
    Here is the start of the svf file:

    FREQUENCY 2E6HZ;
    STATE RESET;
    STATE IDLE;

    SIR 4
    TDI(7)
    TDO(1)
    MASK(F);

    ENDDR DRPAUSE;

    SDR 1
    TDI(1)
    TDO(0)
    MASK(1);

    The first thing done in the file is setting the jtag frequency using the FREQUENCY command.
    No matter what frequency I choose, the frequency measured on the TCK is 1MHz.

    The JTAGLoad tool runs successfully till ENDDR command.
    The SDR command fails with the following error message:

    ERROR:
    "TDO" data is larger than specified number of bits in "SDR" command !
    Error in file [sample.svf], line 14, column 10:
    " TDO(0)"

    Can you please help me understand what I'm doing wrong?

    I'm using the J-Link Software and Documentation pack for Windows version V6.30c.

    Thanks,
    Ben

  • Hello Ben,

    Thank you for your inquiry.
    According to the J-Link user guide UM08001 section 3.10 the frequency command is not applied correctly.
    In the manual you can also find an example implementation.

    It seems that you are working for one of our silicon vendor partners. In that case we suggest using our official support channels per e-mail instead of the forum.
