I am attempting to use the PowerPC simulator with an eCos configuration. I have successfully (I think) built a version of gdb to support the psim target.
I then created a PSIM.ecc file and built the library and tests. When I try to run a test file in gdb, I get an error ' core_find_mapping() - access to unmaped address, attach a default map to handle' $ powerpc-unknown-eabisim-gdb ~/PPCSim/PPCSim_install/tests/services/memalloc/common/v3_0/tests/heapte st . . .
