Need Help about making FRDM-KEAZ128 as debugger

elder_atom — Sun, 19 Aug 2018 03:05:32 GMT

Hello!

I have two FRDM-KEAZ128 boards(named A,B), and I want to use board A as debugger to write program to board B.

I take away the R106 and R101 in the board A and make two boards' SWD_DIO_PTA4(J14 No.2 pin), SWD_CLK(J14 No.4 pin), RST_TGMCU_B(J14 No.10 pin) connected.(showed below)

But there is a problem occured in the debugging process.

Best regards.

This will make SWD_CLK\SWD_DIO_PTA4 of Board A and B connect to KEA of Board B at the same time.
Please try to cut the line at the bottom of J8\J106\J015 for Board B.
And connect the GND signal of two Boards.

Please check the Name of OpenSDA on Board A, make sure it was select when debugging.

Best Regards,

Robin

Thanks a lot about your answer. Could you show me a screenshot about bottom layout for J8\J106\J015? It's helpful for me to cut off the line correctly.
