Please tell how to use the JTAG PORT (only JTAG not EJTAG).
I am trying to use the only the system controller of the IDT but the wiggler (same used for the ARM7)does enter into the debug mode after connection establishment.
What must be the pinouts for the JTAG? Is there any hardware pin to be used to go to the debug mode(as such RTCK in the ARM7 core)?
Presently using following pins:
1. EJTAG_TMS
2. JTAG_TCK
3. NC
4. JTAG_TRST
5. JTAG_TDI
6. JTAG_TDO
7. GND
8. VCC
AND JTAG_TMS is grounded.
I am not sure about the EJTAG_RST pin.
