PTBASE addr This parameter defines the physical memory address where the BDI looks
for the virtual address of the array with the two page table pointers. For
more information see also chapter "Embedded Linux MMU Support".
addr Physical address of the memory used to store the virtual
address of the array with the two page table pointers.
Example: PTBASE 0xf0
REGLIST list With GDB version 5.0, the number of registers read from the target has
been increased. Additional registers like SR’s, BAT’s and SPR’s are re-
quested when you select a specific PowerPC variant with the "set proces-
sor" command (see GDB source file rs6000-tdep.c). In order to be
compatible with older GDB versions and to optimize the time spent to read
registers, this parameter can be used. You can define which register group
is really read from the target. By default STD and FPR are read and trans-
ferred. This default is compatible with older GDB versions. The following
names are use to select a register group:
STD The standard (old) register block. The FPR registers are
not read from the target but transferred. You can’t dis-
able this register group.
FPR The floating point registers are read and transferred.
SR The segment registers.
BAT The IBAT and DBAT registers
SPR The additional special purpose registers
AUX currently not used
ALL Include all register groups
Example: REGLIST STD ; only standard registers
REGLIST STD FPR SPR ; all except SR and BAT
SIO port [baudrate] When this line is present, a TCP/IP channel is routed to the BDI’s RS232
connector. The port parameter defines the TCP port used for this BDI to
host communication. You may choose any port except 0 and the default
Telnet port (23). On the host, open a Telnet session using this port. Now
you should see the UART output in this Telnet session. You can use the
normal Telnet connection to the BDI in parallel, they work completely in-
dependent. Also input to the UART is implemented.
port The TCP/IP port used for the host communication.
baudrate The BDI supports 2400 ... 115200 baud
Example: SIO 7 9600 ;TCP port for virtual IO
QACK LOW When this line is present, the BDI forces the QACK pin (pin 2) on the COP
connector low. By default this pin is not driven by the BDI. Maybe useful
for PPC750 and PPC7400 targets.
Example: QACK LOW ; force QACK low via COP connector
