From ab19de874b887743e0862e6680e561f6fc4f02fa Mon Sep 17 00:00:00 2001 From: Doug Evans Date: Wed, 16 Apr 2014 10:40:41 -0700 Subject: [PATCH] Fix wrapper.exp testcase with stdio gdbserver. * lib/gdbserver-support.exp (gdbserver_default_get_remote_address): Add comment. (gdbserver_default_get_comm_port): New function. (gdbserver_start): Check if board file provided "gdbserver,get_comm_port" and use it if so. * boards/native-stdio-gdbserver.exp (sockethost): Set to "". (gdb,socketport): Set to "stdio". (gdbserver,get_comm_port): Set to ${board}_get_comm_port. (stdio_gdbserver_template): Delete. (${board}_get_remote_address): Update. (${board}_build_remote_cmd): Delete. (${board}_get_comm_port): New function. (${board}_spawn): Update. * boards/remote-stdio-gdbserver.exp (${board}_build_remote_cmd): Delete. (${board}_get_remote_address): Update.
