Hi, We're trying to run the eCos examples such as hello.c and twothreads.c under arm-elf-gdb with "target sim" (cygwin on a Pentium). They seem to work when we remove the calls to printf.
We use the default configuration given by the template ARM Evaluation Board (AEB-1), and configtool-060710.exe malloc seems to work. Why doesn't printf work? It hangs for a while and then exits with the message "ARMulator can't allocate VM page: Cannot allocate memory". On some occasions we got the message "unknown SWI encountered - ffffff - ignoring" but we can't remember how we got it (perhaps when running Insight. The number wasn't always ffffff). This is similar to the message reported here: http://ecos.sourceware.org/ml/ecos-discuss/2003-10/msg00300.html If someone could tell us how to get printf to work under ecos and ARM simulation mode, it would be really helpful.
