*LOG (File Based) •
Log data will be written to a circular buffer, which is stored in file in flash
memory.
•
*LOG
specifies the size in kb, the allowable range is between 50 and 32 x
1024 kb.
•
Log data will include an OS timestamp. When examining timing related issues,
this is much more informative than a time stamp generated on a PC receiving
a log.
•
To upload the logs, Press Bac 4 key simultaneously on VTM menu 1,
or password prompt screen. The log will be uploaded to the device specified
by
*LOGP
, values 1 and U are supported (1 for COM1 port and U for USB
device port).
•
Incremental logs can be obtained by going to the password prompt screen,
uploading the log, and then cancelling VTM password entry prompt. This
upload technique avoids a system restart (entering into VTM menu 1 causes a
system restart).
•
Hardware interrupts are disabled during the writing of log in circular buffer,
overhead of
*LOG
is much less compared to the overhead of
*DEBUG
.
•
Control command G31 with parameter 01O (character 'O' at the end) enables
the
*LOG
logging with size set to 1024 (1MB) and
*LOGP
value to 1.
•
Control command G32 with parameter O retrieves the log one record at a time
until the log is empty.
