I'm not sure what needs to be changed here but it does seem like the instructions provided are too simplistic for how things work currently. 24803 1 srifenbark 2012-09-04 17:01:30 +0000 After talking with Paul Eggleton on this bug he has suggested taking it over and seeing about fixing the issue. Then, once the issue is fixed, I can document it in the manual. For now, I could adjust the manual so that the discussion is more generic and does not suggest specific steps, that in this case, do not work. Scott 24804 2 bluelightning 2012-09-04 17:13:24 +0000 My suggestion for the moment would be to just comment out the bits that talk about running gdb directly from within tmp/sysroots; we can leave in the stuff about using meta-toolchain as I'm pretty confident that should be working. 30850 3 bluelightning 2013-03-19 14:33:15 +0000 The underlying problem seems to be fixed now; I was able to run the produced gdb executable without any errors. There is only one difference now in that there is an extra subdirectory in the path i.e.: tmp/sysroots/<host-arch>/usr/bin/<target-platform>/<target-abi>-gdb e.g. for n450 with Poky on a 64-bit host: tmp/sysroots/x86_64-linux/usr/bin/core2-poky-linux/i586-poky-linux-gdb Scott, could you add this back into the documentation? 30862 4 srifenbark 2013-03-19 17:07:54 +0000 Paul, Here is the updated section: http://www.yoctoproject.org/docs/1.4/dev-manual/dev-manual.html#platdev-gdb-remotedebug-launch-gdb-buildcross Can you look this section over and "okay" it or suggest changes? Thanks, Scott 30953 5 bluelightning 2013-03-21 10:13:02 +0000 Great, thanks. One more thing though - the path in the example above this needs to be updated too. Here's an equivalent path you'd get from building meta-toolchain currently for beagleboard and installing it into the default path: /opt/poky/1.4/sysroots/i686-pokysdk-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi-gdb 30993 6 srifenbark 2013-03-21 15:43:40 +0000 Paul, The change is in. If you okay this I can close this bug. http://www.yoctoproject.org/docs/1.4/dev-manual/dev-manual.html#platdev-gdb-remotedebug-launch-gdb-buildcross Scott 30997 7 srifenbark 2013-03-21 15:53:52 +0000 Made some wording changes to the area right before the updated example. Closing. Scott
