Hello,
anyone here who can reproduce this bug? I use different jtag adapters (ftdi2232 based) with an arm7tdmi target (at91sam7) and calls to the command "mdb 0 100" result in a crash like this (i have append a gdb backtrace): Debug: 284 12101 command.c:145 script_debug(): command - mdb ocd_mdb 0 100 Debug: 286 12106 arm7_9_common.c:2107 arm7_9_read_memory(): address: 0x00000000, size: 0x00000001, count: 0x00000064 *** glibc detected *** ./openocd: free(): invalid pointer: 0x081e3d00 *** Regards, Mathias --- gdb backtrace: #0 0xffffe424 in __kernel_vsyscall () #1 0xb7e57636 in raise () from /lib/libc.so.6 #2 0xb7e58b6c in abort () from /lib/libc.so.6 #3 0xb7e8fe55 in ??
