A thought: We have the setting IMAGE_GEN_DEBUGFS - I have not yet tested. As far as I understand it creates an unstripped sysroot and does not affect target rootfs - is that correct? Does the sysroot created by IMAGE_GEN_DEBUGFS contain the sources? If yes we could set that as sysroot for gdb. I think one of the problems we have here is that there is no reference way documented (or it is outdated) how remote debugging is meant to be performed.
