Hi there,
I flashed two other TonieBoxes with my NodeMCU board and the serial connection works well with manual reset.
On my third box, when running the command
cc3200tool -p COM4 read_all_files extractedFromBox
I got the following output:
Connecting to target…

One or more files could not be verified or read at all
For me, it looks quite strange as there aren’t any filenames listed in the last column of the table (besides mcuimg2.bin & date_time.cfg). On the previous boxes, the table looked similar but all entries had filenames and I was able to read certificates and replace the bootloader e.g.. At this box, this is not possible as the tool/CC3200 doesn’t know where to find the files.
I could try to flash one of the flash dumps of the other boxes but that would mean to overwrite the existing certificates I want to avoid.
Strange thing: the box is not flashed with custom content at all but it’s working as usual: playing custom tonies as long as the content of the ID exists on the SD card and internet connection is blocked.
What I tried out:
- read all files → only two files read (see error above)
- read flash → works, but reading the flash dump gives same result as above
- several restarts/pin connection checks → no effect
Does anyone has another idea how to recover the FAT in the flash and/or to save the certificates? The rest of the flash, I can use the content of the other boxes, but these SSL files, I want to preserve.
