Hi Ben,
I just wanted to report that the problem is solved now.
After sending it in to Shimmer, it turned out that actually the EEPROM
Image was not loaded on this Dock for the SD card manager just as Ben
suspected.
The Shimmer Support stuff fixed it and sent it back to me, and now it is
working properly.
Thanks,
Franz

Franz,
There is a chance that your dock is broken-- Do you have a way to test
with another shimmer dock then you can confirm my suspicion. I think
that either a connector pin has opened or your dock may have shipped
from the factory without the proper factory EEPROM image lopaded for
the SD media controller (in the dock). One of the settings in the
EEPROM sets whether SD WP is logic high or logic low.
I'm going to move this thread to [email protected] and then
you can report back to the list after the issue is resolved.
Thanks,
Ben

Hi JC,
thanks for your reply.
I have tested it again now with the original JustFatLogging Firmware (the
delivered ihex files). I connected the dock to different computers and also
tried two different Shimmer nodes with different SD cards. I also tried it
after formatting the SD and putting it in the Shimmer again.
None of these options worked.
Could it be possible, that there is some setting which I might have changed
accidentally with my (previously installed) custom-designed firmware - and
this setting now persists even when reflashing the device with another
firmware?
Best,
Franz

Hi Franz,
That is unusual; you should be able to delete the files via the dock. Have
you tried replicating the problem with a different SD card? I would also
suggest formatting your micro sd card and trying it again.
Best regards,
JC

Subject: [Shimmer-users] Delete file on SD card
Hi,
I have installed JustFatLogging on my shimmer2 devices. To copy the
recorded data to my windows PC I usually use the Shimmer docking
station. This works well.
But how can I delete files from the SD card?
If I try to do it via the dock, it says "disk is write-protected".
I found a work-around: If I open the shimmer and take out the SD card
and put it in my SD card drive, I can delete files.
But is there also a possibility to delete stored files without opening
the shimmer device?
Thanks,
Franz
