imx6 cpu tap not found in jtag chain

Hi all,

 

I'm trying to connect via JTAG to the MCIMX6UL-EVK with "J-link base" from Segger.

First of all i have removed R1407, R1431~R1434 because JTAG is dedicated with Audio CODEC signals. This is said in Hardware User's guide, page 14.

I have also removed R507 so the JTAG interface is configured to a mode compliant with the IEEE 1149.1 standard, (IMX6ULHDG.pdf)

 

So at this point, i try to connect with no success.

Please, find attached 2 screen captures. One picture with R507 placed (just in case) and another one without it.

 

Check this out and any help will be appreciated.

In device options, i don't see any IMX6.

Though in the screen captures is shown ARM7 as device option, i have tried with cortex-A7 with same results.

 

Thanks and best regards
