Hello. I am working powerpc-eabi with gcc-2.95.3, binutils-2.12.1,
gdb-5.2, newlib-1.10.0 on SuSE 7.2. I have been working successfully
with "-e bug", the MOTBUG OEA environment. I now want to progress
to a custom environment, starting with the "com" device. When I run
a sample program I get the following error:
$ powerpc-eabi-run -f tree.kos5b load5
core_find_mapping() - access to unmaped address,
attach a default map to handle this
- addr=0xf0003005 nr_bytes=0x1 processor=0x40141008 cia=0x57c0
The file tree.kos5b (with some cruft from trial-n-error) is ...
/#address-cells 2
/cpus/cpu@0
/openprom/options
./oea-memory-size 0x400000
/memory@0/available 0 0x400000
/memory@0/reg 0 0x400000
/chosen
/packages
/iobus@0xf0000000
/iobus@0xf0000000/reg 0xf0000000 0x01000000
/iobus@0xf0000000/com@0xf0004000/reg 0xf0004000 8
/iobus@0xf0000000/com@0xf0004000 > 0 int /cpus/cpu@0x0
My guess is that I need to add memory map for the iobus.
If this is this right, how do I do it?
If not, what do I need to do?
Any help would be appreciated.
Thanks,
Matt
