"Failed to correctly configure the JTAG Chain" problem occurred during CW debug attaching with our T2080 processor board.

[karunakaranradh]

While try to connecting the code warrior USB Tap with our processor board, it shows "Failed to correctly configure the JTAG Chain".

In debug configuration, connection type was changed with our RCW jtag chain file which is generated in QCVS(QorIQ Configuration Validation Suit) project.

and also tried with T2080 sample RCW jtag chain file which is available in code warrior IDE..

(Note: T2080(PTB) Rev 1.1  processor using for board bring up).

1) What are all the possible reason for this error?

2) Whether RCW wrong data input will cause this error?

Hi Karunakaran Radhakrishnan,

This could be caused by bad RCW. Where's the target RCW from?  From the JTAG file? I find in the picture that the debug session type used is "attach", can you please try to use "connect" to have a test, choose configuration "SRAM" for the test.

Another question is how many devices on the JTAG chain?

Have a great day,
Lunmin

Hi,

I am also facing the same issue i.e.

CCSProtocolPlugin : Failed to correctly configure the JTAG chain.

I am using the RCW T2080 (2 0x80000001) (210001 0x0a09000f) (210002 0x0f000000) (210003 0x00000000) (210004 0x00000000) (210005 0x6c160002) (210006 0x00804200) (210007 0xfc026000) (210008 0xa0000000) (210009 0x00000000) (210010 0x00000000) (210011 0x00000000) (210012 0x0103b7fc) (210013 0x00000000) (210014 0x0000000d) (210015 0x00000000) (210016 0x00000004)

I have enabled the JTAG diagnostics & tried to connect again.

While JTAG diagnostics test, IR Scan test has been failed.

Kindly suggest me the solution.

Hi Lunmin,

Thanks for your reply.

Another question is how many devices on the JTAG chain?

     Only one processor connection available in the JTAG chain.

-----------------------------------------------

I am creating new connection project, with that also causes the same error.

Afterward, we are loaded RCW data with our method. Again, I am trying to connect through code warrior tap,

Now it shows "Core Not Responding" error.

What is your method to load RCW. For me "Failed to correctly configure the JTAG Chain" and "Core Not Responding" after the RCW was flashed on target board, looks like wrong/incorrect/missing RCW.

Hi Adrian,

Thanks for your reply.

I could not found, what was the problem.

With the following changes, it was working fine:

1) Project created with SRAM connect.

2) Select the JTAG file in the debug configuration without initialization.

(My JTAG File: T2080 (2 0x80000001) (210001 0x0a00100f) (210002 0x0f000000) (210003 0x00000000) (210004 0x00000000) (210005 0x6c1f0002) (210006 0x00804200) (210007 0xfc025000) (210008 0xA0000000) (210009 0x00000000) (210010 0x00000000) (210011 0x00000000) (210012 0x010337fc) (210013 0x00000000) (210014 0x0000000d) (210015 0x00000000) (210016 0x00000004))

3) As suggested in Errata (A-007980), RCW cfg_rcw_src source selected as Hard coded RCW (i.e by pass the PLB).
