I use a PEMICRO Multilink universal (rev B) for several years.


Now I'm working with a KL17Z256VLH4, KDS3.2 and KSDK2.0 freertos (window seven 64bit pro)


>>>Multilink universal to debug an FRDM K64F -> It's all good

>>>FRDM K64F as debug tool with my board KL17 -> it's all good. OpenOCD is terribly slow but it works perfectly


>>>Multilink universal to debug my board KL17 -> unusable

KDS does not see the debug tool frequently (requires disconnecting / reconnecting every time)

The communication fails half the time

Once in debug operation, communication disconnect after a few seconds of inactivity, every time


The same board works well with this debug tool, Code Warrior and a KL15 chip.


Multilink universal is up to date for driver and firmware.


I'm testing for a week now !

today, to move forward a bit I'm using OpenOCD with FRDM K64F ... very very slowly :-(


What is the problem ?

incompatibility ?

bug in algo  ? (C:\Freescale\KDS_v3\eclipse\plugins\com.pemicro.debug.gdbjtag.pne_2.3.6.201602211227\win32\gdi\P&E\supportFiles_ARM\NXP\KL1x)

What else ? Bord is working well, debug tool too. Only with KL17, KDS is mismanaging the multilink universal.


Thank you in advance
