#207 OpenOCD sends debug and warning messages to the stderr

[Roman]

OpenOCD sends debug and warning messages to the stderr.

Expected result: Debug and warning, info messages should be sent to stdout. Error messages should be sent to the stderr.

Actual result: All messages (debug, warning, error) messages are sent to the stderr

OpenOCD can be used in "pipe" from within GDB.
From doc/openocd.texi:

A pipe connection is typically started as follows:
@example
target extended-remote | \
openocd -c "gdb_port pipe; log_output openocd.log"
@end example
This would cause GDB to run OpenOCD and communicate using pipes (stdin/stdout).

To avoid mixing LOGs with GDB communication, all OpenOCD output is by default sent to stderr.
Nevertheless it can be redirected wherever you want with the "log_output" command.
If you want it on stdout you can, on Linux, add on commandline "-c log_outupt /dev/stdout"

For me this ticket is not valid and should be closed

Do you know what the equivalent is on Windows?

[Antonio Borneo]

I always forget about Windows!
Have you tried either "CON" or "CON:" ?

If it doesn't work we would need adding hooks in OpenOCD to intercept the string "/dev/stdout" or "stdout" and redirect the log.
