Dear all,
I uses MCB2300 ver3(LPC2360 on it). JTAG connection has no problem. I bought JTAGJet-Trace256K(signum), and a tyco-amp connector for ETM coneection whose pattern is printed on MCB2300. I exactly soldered a connector to MCB2300 boards 'ETM'. I checked all pins with schematics PDF file which is provided by keil. they were no problems.
But, when I connect my JTAGJet-Trace, JTAGJet couldn't recognize TRACE and even JTAG connection.
Then, I asked Signum cooperation. They answered, ETM wiring on MCB2300 is incorrect.
Can not ETM function work on my MCB2300? or, somehow Can I use ETM?
please advise.
your answer is greatly appreciated.
Kind Regards.
Thank you for your answer.
But, JTAGJetTrace-256k can use JTAG socket on MCB2300. This means, Debug or Download such as same function as ULINK/ULINK2 can be used with JTAGJetTrace.
This cannot only use ETM on MCB2300.
Though the ETM foot print on MCB2300 board is prepared, both ULINK and ULINK2 seem not to have the trace function, I think.
and, JTAGJet-Trace is also not available as you say. What for The ETM foot print on MCB2300?
Please advise.
Any answers will be greatly appreciated.
"But, JTAGJetTrace-256k can use JTAG socket on MCB2300."
Can it?
Yes, it can work with JTAG socket. it cannot work with ETM socket.
"it can work with JTAG socket"
There is no such thing as a "JTAG Socket"
JTAG specifies the signals on the interface, but does not specify any particular connector nor any particular pinout. Thus it is meaningless to just say, "JTAG Socket" - you need to state the specific connector and the specific pinout.
There is no reson to assume that the connector & pinout used by Keil for their own products will be compatible with any other products from any other providers!
