56F8367 troubleshooting with UNVERSAL FX programmer

Staff: Johnny N.

  • I usually use a multilink universal FX to program kinetis KV46
    with a PROGACMP software with MINI G connector which work correctly.

    Now I try to program a 56F8367 with PROG DSC software (Version 9.40.00)
    through PORTA connector (14 ports adapted to JTAG/OnCE 56F8367)

    I have troobleshooting : Target is not responding

    By looking at signals :
    Reset is driven Low.
    TCK is OK but TDI seems to be to heavily charged and my target doesn't respond. (This line is only connected to the micro controler)
    If I disconnect this signal from the target the signal is OK.
    Do I need to buffer the TDI link in order to get a correct signal on the target.(or a pull up resistor)

    I also try to change the speed of jtag programming
    but all the choice on DEBUG shift speed give the same TCK clock : does anybody experiment different speed with this firmware (Version 9.40.00) and PORTA connector for DSC.

    thank you for your help.
