Broken FAT: overlapping entry at block

Toniebox Hardware CC3200 (V1, V2)
1

Hello 0xbadbee, I have the identical problem with “broken FAT”. Additionally there are problems with the command:
cc3200tool -if firmware.dmp read_all_files extract/
. For 5 minutes dots are displayed on the screen, but the content of the extract folder does not increase.

I would like to switch to the develop branch of the cc3200 tool, can you tell me how to do this? I have always followed the newbie guides, but unfortunately I don’t know how to change the branch when calling

pip install git+git://github.com/toniebox-reverse-engineering/cc3200tool.git

with it.

Kind regards,
Daniel

There is no need to switch to develop, as the changes are already integrated in the stable version.

Good to know, thank you for the quick response.
The Toniebox is from Tonie’s refurbish program, could it be that the memory card has an error or is the command

cc3200tool -if firmware.dmp read_all_files extract/

only read the data from internal chips?

It is not clear to me what is your problem or what you did in detail or tried.
You are also sharing any logs…

Sorry, I was so caught up in the topic that everything was clear to me, but nobody else has all the information to help.

I have followed the instructions Teddycloud CC3200 newbie guide and am at the ‘Create backup’ step.

My setup is as follows:

After connecting the box to the UART connector and the computer, additionally connect the charger to the Toniebox, green LED lights up continuously, then send the command

cc3200tool -p /dev/ttyUSB0 --reset dtr read_all_files ExtractedFromBox/ read_flash backup.bin

executed.

Now I get the error ‘broken FAT’ like @mr_white. This error occurs on both Windows and Linux.

If I add the parameter ‘–size 4194304 --ignore-max-size’ I get this error:

In the meantime, I have reassembled the box, but it does not start correctly, the green LED flashes a few times, then only individually at longer intervals, and no sound is played.

I hope the box can be given new life again.

I have another Toniebox at home, with a CC3235 chipset, and the procedure was somehow easier there.

Kind regards
Daniel

The error indicates wrong syntax.
Please post your full command. You can’t just put it at the end. It works only directly after read_flash.

7

So far I have used the additional parameters as follows

cc3200tool -p /dev/ttyUSB0 --reset dtr --size 4194304 --ignore-max-size read_all_files ExtractedFromBox/ read_flash backup.bin

I have just tried it in different constellations but can’t get it to work.
Can you please send me the command that should work?

8

As said previously:

Also please remove the read_all_files block. You want to dump the flash without fiddling with the files.

I cannot craft you a valid command, as I have no access to the cc3200tool currently to test this.

Is it possible that I am using a broken / incorrectly set up cc3200tool version? I have been using the tool since I modified a CC3235 box.

This looks like a connection problem. Either due to your wiring, your UART or your USB-port/computer.

I don’t think it makes sense to install the custom bootloader, if your box is not booting at all.

Were you able to do a read_all_files or how you extracted the flash files?

This should be fine.

I have tried it with different cable lengths, reconnected everything and also different computers.

read_flash and read_all_files in one command on all my systems always leads to the “cc3200tool.cc.CC3200Error: broken FAT: overlapping entry at block 256 (prev end was 265)” error.

In case anyone runs into the same error, I fixed it by doing a reset, see Bricked my box?, then started all over again.

Whatever caused the broken FAT error is now gone.

Many thanks to 0xbadbee for the quick answers to my questions and the helpful support.
