Error trace shows nothing in memory window

[xiulipan]

Now trace_error will show nothing in memory window. Either rmbox or logger will show nothing in error trace. Even cat the debugfs will show empty.

Error trace may be broken with new logging

See #473 for similar symptoms

@ZhendanYang needs validated and closed.

On up2 with nocodec, rmbox and logger are still empty, while rmbox -t and logger -t are not.

[cujomalainey]

Still seeing empty logs as well on glk with sof_logger -t

[cujomalainey]

@akloniex why are there two logger binaries? Which one am I supposed to be using? We should delete the other one otherwise this is confusing.

[akloniex]

@cujomalainey Only 1 binary of sof-logger is built in the make process, You probably have some leftovers from previous runs. Please cleanup your workspace, e.g. git clean -f
@ZhendanYang Please verify if the issue occurs on revisions following PR #490 and update this issue accordingly. Thank you.

@akloniex yep that was the issue. Sorry, I should have checked that before. I was thrown by the simultaneous name change and location move.

@akloniex
I did some tests on up2 with codec. I introduced XRUN injection when playback. and sof-logger -t showed some errors in red color words:

But sof-logger without the parameter -t still showed nothing:

@ZhendanYang @keqiaozhang logger will output to different file w/o parameter -t. Please check thesofproject/soft#104 and check if this is a fake issue.
