ARM processor running FreeRTOS.
I have the trace hooks worked out. And that calls a
specific routine to
generate a trace packet.
I did have it working for task_switched_in and
task_switched_out.
Something broke.
The init routine writes the main header and packet
context, then writes
one event packet per event. The ARM processor is
single core.
I get the usual error (I suppose): error initializing
trace. "Failed to
get CTF Iterator for path (path)" The path exists,
the file is there.
I've searched for a set of error messages with causes,
haven't found them.
I've gotten the same error regardless of a number of
changes. To me,
the error message says "file does not exist", which
may really mean
"file can't be parsed". The metadata file seems fine,
doesn't generate
any error messages.
So something is wrong, but I'm not sure what, and at
this point, don't
know how to find out what. The binary file output
seems correct to me.
(maybe obviously not).
Processor dumps binary trace data to a 1 mbyte buffer
(QSPI RAM), then
that's sent to a file by using the eclipse memory
manager. File looks
good. metadata looks good.
Assistance, please.
