Details

crash.log is a temp file used to append to crash.log (tffs), which is a character device.

This simplified excerpt from 7272 supportdata fw 6.83 explains it best:

cat /var/flash/crash.log > /var/tmp/crash.log

echo "sent on: `date` by supportdata" >> /var/tmp/crash.log

cat /var/tmp/crash.log > /var/flash/crash.log

This is a workaround for the character devices of the TFFS since this would not work:

echo "sent on: `date` by supportdata" >> /var/flash/crash.log

A character device is a stream and does not have a file size, thus the >> could not seek the end.

A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Showing all models using this temp file. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
