using S32K144 EVB as JTAG to debug other S32K144 chip

Contributor I


I have a NXP s32k144 EVB, it works normal. Now i designed my own S32K144 board, and i have tried Multilink to debug it. it is OK. However, the Multilink is shared. So i want to use EVB's JTAG interface( J12, SDA jtag interface). 

First, i  pick out the U7, U10 to make openSDA disconnect with the EVB S32k144 chip, then i tried the J12 interface with my new s32k144 board, the "P&E connection assistant" window occurs, it says "an error occurs while connecting to the interface hardware" the openSDA can be recognized.

Then i picked out the S32K144 chip from the EVB board. But the S32DS IDE still can not debug. the error is the same. 

So i want to know what should i do to make it work as a JTAG. i have read the link

"Using the Freedom Board as SWD Programmer".  Thank you.

yes, it is definitely possible. Is your board powered? Please check board schematic if it is connected properly to your EVB -   

Hope it helps.
