Hello community,
I have a trouble with my T2080 custom board(discreate DRAM) and CodeWarrior.
I am trying to valid the DDR with the QCVS DDR Validation Tool, however the connection is always refused regardless of the JTAG clock speed chosen.
The log from the ccs server is:
(bin) 7 % source IDcode.tcl

My custom board JTAG interface hardware design is similar as the T2080 data sheet(Legacy JTAG interface connection).
What are the causes "error: T2080: Core not responding" ?
Can anyone help me please.
Best regards,
