DEBUGTAP <tap> Specifies the TAP number which needs to be activated to get the
core TAP in the JTAG chain. E.g. ARM11 TAP if you intend to
debug an ARM11.
Used if MULTITAP=Icepickx.
ETBTAP <tap> Specifies the TAP number which needs to be activated to get the
ETB TAP in the JTAG chain.
Used if MULTITAP=Icepickx. ETB = Embedded Trace Buffer.
MULTITAP
[NONE | IcepickA | IcepickB
| IcepickC | IcepickD |
IcepickBB | IcepickBC |
IcepickCC | IcepickDD |
S T C LTA P 1 | S T C LTA P 2 |
STCLTAP3 | MSMTAP
<irlength> <irvalue>
<drlength> <drvalue>]
Selects the type and version of the MULTITAP.
In case of MSMTAP you need to add parameters which specify
which IR pattern and DR pattern needed to be shifted by the
debugger to initialize the MSMTAP. Please note some of these
parameters need a decimal input (dot at the end).
IcepickXY means that there is an Icepick version “X” which
includes a subsystem with an Icepick of version “Y”.
NJCR <tap> Number of a Non-JTAG Control Register (NJCR) which shall be
used by the debugger.
Used if MULTITAP=Icepickx.
RTPTAP <tap> Specifies the TAP number which needs to be activated to get the
RTP TAP in the JTAG chain.
Used if MULTITAP=Icepickx. RTP = RAM Trace Port.
SLAVETAP <tap> Specifies the TAP number to get the Icepick of the sub-system in
the JTAG scan chain.
Used if MULTITAP=IcepickXY (two Icepicks).
