I just read through the users manual for the LPC2114 and from what i can deduce the ETM output can be individually disabled simply by not tying a pull up resisitor to P1.20/TRACESYNC. I.e. you should be able to use the ETM port pins as normal IO pins while debugging through the J

Hello, Can anyone double check my understanding please. On LPC2114 you can enable JTAG or ETM or both. When enabeling JTAG only you can use the ETM pins as I/O; therefore, only 6 pins are needed to connect to the chip and debug and all the rest of the pins can be I/O

Using a wriggler with a 2106 it seems that the ETM pins also get activated when starting in DEBUG. Is there any way to disable this, the wriggler does not even connect to them but as far as I can see there is no way to do it with PINSEL on this chip. Is it possible via JTAG?

Dominic, My apologies. I misread nSRTS as nTRST, and I incorrectly referred to EmbeddedICE-RT macrocell as ETM -- I did not meant to discuss ETM at all.

Hi, I'm planning to use a LPC2138 and LPC2214 in a motor control system. As the motors being controlled are upwards of 50kW, it will not be easy to stop the processor and single step through code. Therefore I'm interested in the ETM trace feature of the LPC2xxx. Does anyone

Hi, In the manual it says that the ETM pins (P0.22-P0.32) are active when DBGSEL and RTCK is high during RESET! I am reading page 72 and page 206 in the LPC210x manual from Oct. 02, 2003. Does this mean that P0.22 - P0.31 not can be used when using a JTAG

It will not stream the trace data in real-time to the PC (allowing greater / vitually unlimited) instruction trace capabilities. ...

Hello everybody, I'm currently working with a NXP LPC3180 because it features an ETB (Embedded Trace Buffer) which allows trace data to be retrieved via JTAG instead of the high-speed ETM interface.

I would be nice if my code could detect whether the JTAG interface is connected. I do this now with LPC213X by looking at (PINSELECT2 & 0x4), and can control power save modes, etc. Since the JTAG pins are dedicated on the LPC236X, there is no PINSELECT state to view. If RTCK is grounded, JTAG AND ETM are enabled, and a bit in PINSELECT10 is set/cleared. However, JTAG only is enabled by ...
