Description Sergio Durigan Junior 2012-09-14 19:41:22 UTC I could not find an easy way to reproduce this bug so far. The only way I managed to do so was to: 1) git clone git://git.qemu.org/qemu.git 2) ./configure --enable-kvm --python=python2 --target-list=x86_64-softmmu --disable-uuid --disable-werror --enable-debug --enable-fdt # you will https://sourceware.org/bugzilla/show_bug.cgi?id=14585 need to install the dependencies 3) gdb -q -ex 'run' /tmp/install-qemu/bin/qemu-system-x86_64 And you will see: Warning: Cannot insert breakpoint -1. Error accessing memory address 0x34e96c: Input/output error. Running git-bisect on gdb.git, I found the culprit as being: a7262466d02155f5f70422804e5971f8d5e78118 is the first bad commit commit a7262466d02155f5f70422804e5971f8d5e78118 Author: Tom Tromey

My design includes a NIOS II processor with the JTAG Debug Module set to Level 1. I've build the cannot insert breakpoint design and programmed the corresponding .pof file into the device. In the NIOS II IDE, when I try to Debug NIOS II HW, it appears that I connect to the debugger, as I get the following messages: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x00000270: verified Listening on port 1923 for connection from GDB: 59saccepted However, I then get the following messages: mi_cmd_stack_list_frames: No stack. No symbol "new" in current context. Warning: Cannot insert breakpoint 1. Error accessing memory address 0x16714: Unknown error 4294967295. Has anyone seen this error before, and know how I can fix it? I've seen posts for similar errors in the forum, but they don't have any responses.

What resides at the above address (0x16714)? If it's flash, you won't be able to set a break point there without adding "hardware breakpoints" to your Nios II CPU and re-building in SoPC
