How to decode crash trace value received for AVL ID 257 ?

Crash trace value as below

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

Hello.

AVL ID 257 has axis data.

If this exactly what You get on element with AVL ID 257, then it simply decodes like this:

first 2 bytes X axis data, next 2 bytes Y  axis data, next 2 bytes Z axis data, and then repeat as long as there are data on this element. Decode it from HEX to dec to get value in mG.

Best Regards

if you are using trace full, how does the string then change to fit I/O data also?

Hello.

This IO (AVL ID 257) element has variable size (Codec8E has to be used) and also it is very likely that record this big can be split into multiple records if crash trace record was made at high rate. As maximum AVL packet size is 1280 bytes for FMX1, FMX0, FMB9 devices.
