Hi,
I am having trouble getting PSIM to simulate a 603e processor (operating
environment). With the device tree shown below, I can execute
privileged instructions so I am in the operating environment but I
cannot access any of the OEA registers (and it is trying to read AltiVec
registers which comes up with an error). Here is what I have done:
First, I built and installed gdb 5.2.1 as follows:
bash$ ../gdb-5.2.1/configure --prefix=/opt/gcc-ppc-3.1.1
--build=sparc-sun-solaris2.8 --host=sparc-sun-solaris2.8
--target=powerpc-eabi --enable-sim-powerpc
bash$ make
bash# make install
Next, I created a device tree in a file named psim.tree as follows (note
the specification of the 603e processor and operating mode):
/openprom/init/register/msr 0x40
/openprom/init/register/sp 0x100000
/openprom/trace/dump-device-tree 0x0
/openprom/options/env "operating"
/openprom/options/model "603e"
/openprom/options/oea-interrupt-prefix 0x1
/openprom/vm/stack-base 0xf0000
/openprom/vm/nr-bytes 0x10000
Next, I load my bare board executable as follows:
$ powerpc-eabi-gdb main.elf
(gdb) target sim -f psim.tree
(gdb) load main.elf
(gdb) break main
(gdb) run
(gdb) info all-registers

hid0: invalid register
(gdb) show architecture
The target architecture is set automatically (currently powerpc:common)
(gdb) set architecture
Requires an argument. Valid arguments are rs6000:6000, rs6000:rs1,
rs6000:rsc, rs6000:rs2, powerpc:common, auto.
Note that I don't get any choices of PowerPC besides common although I
see support for the 403, 403GC, 505, 860/850, 601, 602, 603/603e,
604/604e, 750/740 and 7400 in gdb/rs6000-tdep.c.
I have also tried adding the --with-cpu=603e option to configure but
that didn't seem to change anything. Can anyone tell me what I am doing
wrong?
Thanks!
