Hi,
Tom is right - the EPI JEENI doesn't support the ARM7TDMI-S core. This
is a part of an email I got from EPI:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As you know, the main difference between the ARM7TDMI and ARM7TDMI-S
processors is that the ARM7TDMI-S core incorporates the use of RTCK.
Unfortunately, the JEENI probe does not have support for RTCK. Adding
support for this is not in the plans, since the JEENI probe has
reached an end-of-development status.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So I have to use an other JTAG-Probe.
