Hello! I'm just beginning to play around with embedded systems, so please be patient ;-) I made binutils (2.9), gcc (2.95.2) and gdb (4.18) for hostsystem linux and target i960-unknown-coff. the compiler worked, as far as i can see (if i compile a simple "hello word" programm i get an executable). now i wanted to test, if the executable makes something useful, and i tried with gdb. maybe i asume something wrong here, but i thought the "target sim" in gdb would be a fine thing to test the binary. but whenever i try to do this i get a segmentation fault. i also tried i960-sim-coff as target for gdb - same results. i worked out, that in the function "sim_open" in file "sim-if.c" under "sim/i960/" a null reference is used. in this code (from line 146 to line 149 in this file): ------------------- /* Open a copy of the cpu descriptor table. */ { CGEN_CPU_DESC cd = i960_cgen_cpu_open (STATE_ARCHITECTURE (sd)->mach, CGEN_ENDIAN_LITTLE); ------------------- "STATE_ARCHITECTURE (sd)" returns NULL, and therefore it segfaults when trying to access "STATE_ARCHITECTURE (sd)->mach"... hmm - sounds like a bug-report ;-) but i think, that i have done something wrong when configuring, or compiling gdb, or i don't understand that "target sim" and want to know, what i could have done wrong. yours -- Helmut Kolb KNAPP Logistik & Automation G.m.b.H.
