Summary: eCos GDB stub "detach" reply incompatible with GDB
7.4.1
Product: eCos
Version: CVS
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: normal
Component: GDB stubs
AssignedTo: unassigned@bugs.ecos.sourceware.org
ReportedBy: john@dallaway.org.uk
CC: ecos-bugs@ecos.sourceware.org
Class: Advice Request
The generic eCos GDB stub code replies to a "D" detach packet with an empty
string. This causes GDB 7.4.1 to report "Remote doesn't know to detach".
According to GDB documentation, the GDB stub should reply "OK" to indicate
success - otherwise GDB will believe it is still attached to the target:
(gdb) det
Sending packet: $qTStatus#49...Ack
Packet received:
Sending packet: $D#44...Ack
Packet received:
Remote doesn't know how to detach
(gdb)
Older GDB will interpret a reply of either "OK" or an empty string as an
indication of success (tested with GDB 5.3).
Patch to follow.
