Question

Several trackers have a problem with updating firmware. Error:Failed to write to file @ SD card

Answer 1

Either SD card is bad and FW fails to write information to it.

Or maybe there's not enough space.

Have you tried for example formatting device SD card and tying again?

or changing SD card?

Sure, i tried several times sdformat command via sms and restart of tracker.

The trackers was installed on the clients cars and replacing sdcards is not a solution.

Is there any other solution?

If you tried sdformat -> and after that device still fails with FW update (multiple attempts at fw update).

It means that SD card has gone bad. Nothing you can do to fix this now.

You have to replace sd card.

Yes, but firmware was uploaded successfully. Also most probably it should be written to internal memory not to the sd card.

The question is still open...

FW size is 4MB, internal TOTAL size is 4MB. Theres no space.

So downloaded FW update file is stored in external storage SD/NAND and then update is performed.

If message is failed to write - it means error happens during transmission and FW is not able to write certain chunks into SD. Might be bad sectors or bad sd card in general.

I suggest changing SD card.

Theres nothing to do from FW size, so ...
