I was informed unequivocally by EPI that the LPC family (and any other
-S series ARM core) was *not* supported by JEENI specifically due to
the lack of the RTCK interface. This is what forced me to buy another
JTAG unit to work with the LPCs, specifically, a BDI2000, since I
needed to continue to use the GDB server-based interface.
Abitron also stated that the RTCK support was mandatory, quoting the
same paragraph from the ARM7DMI-S spec noted in an earlier message.
If this pin really isn't necessary for correct data timing, then
Philips needs to get the message out to all the JTAG debugger people.
