10.1i iMPACT - Cannot perform Readback on the device which is not the first one in the JTAG chain


When I try perform a Readback operation on any device except the first one in the JTAG chain, I see the following message:

'<position number>': No file name specified...

'<position number>': Readback terminated.

PROGRESS_END - End Operation.

Elapsed time = 0 sec.


This is a known issue and is resolved starting with iMPACT 10.1 Service Pack 3.

The work-around for current version is to use the iMPACT in Batch Mode in a command prompt. For example:

setMode -bs

setCable -port auto


ReadbackToFile -p <position number> -file <FileName>.mcs

Another work-around is to go back to 9.2i or earlier.
