DDRv gives me this error: Error configuring the target! - 'Context path CCSR unresolved'

Hello,

When trying to run the tool on my board I got this error:

Exception: (<<Error configuring the target! - 'Context path CCSR unresolved'>>)
--------------------------------------------------------------------
Target system was initialized 0 times and it took 0.000000 seconds.
Target system effective test execution took 0.000000 seconds.

I'm connection to a target in a JTAG chain of two devices (one is the T1022). The original "connect_call.py" from the DDRv tool was modified in order to achieve a successful connection with this JTAG chain configuration.

The tool works fine if a restore the original "connect_call.py" file and use a board with only the T1022 in the JTAG chain.

Please attache ccs log when this error is happen.

devlist: t10xx indicate that you use the original connect.py and connect_call.py. When using the modify files, both devices should be visible in ccs.

Please find the new log below. This time with the modified files "connect.py" and "connect_call.py". Now it doesn't even connect to the target.

This is the same situation as before. My guess is that the reset of your board is not consistent. Try to hard reset your board, then use DDRv to connect to it. Also, you could try followings ccs commands to make sure reset is working ok:

config cc cwtap

ccs::config_chain t10xx

ccs::reset_to_debug

I found the problem: in line 107 of the modified "connect.py" I changed from "CCSR = getCCSRContextPath()" to "CCSR = get_ccsr_space()" and it worked as expected.

[tiagobrusamarel]

Reset is working as expected.

[tiagobrusamarel]

I'm using the original "connect.py" only. May be the problem... gonna check again.
