M. Heard <heard@pobox.com> described as: + + The purpose of the patch is to make the stub ignore all + characters except '+' (ack) or '-' (nak) when it has transmitted a + packet and expects an acknowledgment. Without the patch, + putpacket() will retransmit each time it receives anything other + than '+' when expecting an ack, and that, bitter experience has + found, frequently results in the stub failing to sync up when + initially attaching to gdb. + + I think that rtems users will notice significant improvement in + the of the mips stub if this patch is incorporated in the + distribution; certainly I did in my stand-aline environment. I + should hasten to add that it is only an improvement and not a 100% + cure for synchronization problems because '+' characters can (and + do) during as message data, and it's still possible for these to + be mistaken as acks. I have no idea how to fix that short of + redesigning the gdb-remote protocol. + 2002-11-01 Joel Sherrill <joel@OARcorp.com> * mips-stub.c: Removed warnings. |
