How to connect Trace32 to i.mx6Quad SABRE-SD board

Hello.

I've just got development board yesterday.

I didn't change anything of board.

When I connected Trace32 debugger on J6(JTAG Connector), PowerView of Trace32 said 'debug port failed'.

How can I connect Trace32 to the board?

Dear Min1,

The message means, that the debugger is not reaching the debug components on the target. If the own setup is not working, then I would suggest first trying one of the official demo scripts, in this case the script:

    DO ~~/demo/arm/hardware/imx6/sabrelite/imx6quad_smp_sieve_sram.cmm

The script first connects to core 0, then wakes up the other cores and opens an SMP debug session for all cores.

In the case the script is also showing a bus error, then let's check the JTAG connection by scanning the daisy chain of your target:

   AREA.view
   SYStem.Option TRST OFF
   SYStem.Option EnReset OFF
   SYStem.DETECT DaisyChain

What is shown in the AREA window?

Best Regards,

Steffen.
