Re: [Paparazzi-devel] tlm decode error

[Gautier Hattenberger]

Hi,

It seems the data logger missed a few bytes and got out of sync for a few messages. It actually has nothing to do with the I2C_ERRORS message.
If you want to fix it, you look for a way to remove the following sequence of bytes in the tlm file:

99 45 00 00 45 33 00 42 fd ca c9 00 00 47 44 17 46 ad 99 14 14 23 28 c4 13 12 49 f5 c1 ca c9 00 00 47 44 17 90 9e 99 14 14 23 29 80 14 12 49 5b c7 ca c9 00 00 47 44 17 ba 0a 99 14 14 23 2a 97 13 12 49 00 cc ca c9 00 00 47 44 17 a6

If you manage to remove this sequence, it can be enough to finish the parsing (unless you have an error further in the file). You'll loose 4 WP_MOVED messages, and 3 of them can be rebuild if really necessary, 1 is lost.
