How can I use JTAG mode without ETM port on Philips LPC 210x?
I pull up DBGSEL and RTCK during RESET, processor starts using jtag but also ETM port is enabled (I can`t use ETM pins as GPIO). I am also using LPC 212x - it is posible to turn on jtag without ETM port.
Thank You
On the LPC210x you can use the secondary JTAG port, providing that your on-chip software enables it.

port.
Thank You
I know about it but I don`t know how to do it. It is written in Philips Data Sheet to this processor but it is not clear for me. If you can send me more details how can I do it. I am using gcc and Wiggler from Macraigor.
I am using also philips lpc 2124 (demo board from KEIL MCB2100). It is working with JTAG port but without ETM (RTCK pin to GND during reset). This doesn`t work on philips lpc2106 (data sheet says that you have to pull up DBGSEL and RTCK during reset - JTAG port AND ETM is enabled).
Thank You for information and please send me more details if you can.
