The log files are written to the USB thumb drive when the USB thumb drive is inserted into the SR25. So try the following:
- Plug the USB thumb drive into a laptop and remove everything but SR25.ZIP
- Power on the SR25
- Insert the thumb drive into the SR25
- Watch the lights on the USB thumb drive and wait for some flashing
- Unplug the USB thumb drive
- Plug the USB thumb drive into a laptop and look for log files.
The log files will only be written if the SR25 sees the SR25.ZIP file on the thumb drive and validates its signature. If it does not see the SR25.ZIP file as valid then it will not write any log files. So at this point, if you have log files on the thumb drive, we can take a look and see what is going on. If you do NOT have log files then there is something about the SR25.ZIP file that the SR25 is not liking.
The SR25.ZIP file is keyed. If you manually change it in any way it will be made invalid. Only take the SR25.ZIP file from the base and place it on the thumb drive. Never modify any of the SR25.ZIP contents.
I have already done those steps. Also, this is a SR25.zip that was working. I only replaced the zip file while troubleshooting. What is confusing is the lack of log files. Even the txt file does not show up, which led me to believe that I may have "locked" the thumb drive, but that was not the case. I am trying a new thumb drive today with a new sr25 and new download of the zip file. I will let you know how it goes. Thanks for the feedback John.
The log files are only written to the USB if the SR25 sees the SR25.ZIP file as valid. So the fact that we're not seeing log files is pointing in that direction. Trying a different USB drive and a different SR25 are great next steps. Let us know how it works out.
The way in which an SR25 unit writes its log files has changed a bit over time (i.e. firmware version). Very early SR25 firmware did not write a file at all. Later firmware versions write a file, but perhaps not when you expect it to be written. The most recent firmware versions write log files to USB every few seconds, which greatly helps to minimize confusion.
Since you are not seeing a log file being written to the unit, please try this:
1. Start with a clean (i.e. reset) SR25 unit.
2. Insert the USB stick with SR25.zip file. Wait until the LEDs settle in to the pattern you are used to seeing.
3. Remove the USB stick and then reinsert it. *(This is the key for older firmware versions. The logs are written on re-insertion of the USB stick.)
4. Wait a few minutes, remove the USB stick and inspect for log files.
Just out of curiosity, how long ago did you receive that SR25 unit?
I tried the following and no logs
"Remove the USB stick and then reinsert it. *(This is the key for older firmware versions. The logs are written on re-insertion of the USB stick.)"
"Just out of curiosity, how long ago did you receive that SR25 unit?" No more than 6 months ago.
