Hello,
I'm trying to debug an app with ozone 3.10e and jtrace pro cortex-m on stm32F412.
In a nutshell, I have an iissue with hardware watchdog fired during flash erasing / writing.
To toubleshoot, I disabled the watchdog. Here a screenshot of timeline.
On the data panel, there's a green line that goes to 1 then to 0, flash operations happens
during this period.
The issue is that all trace information is loose from the begining of the capture to the last
write operation of the capture.

Here is a second screenshot in which I stop the process during the write operation. You can see
that I have only 120 ms of measure (while around 1.5 second during "normal" operation).

The third screenshot is a zoom on the second one where you can see the last flash write operation
captured.

I'm blind in the most interesting part. What can I do ?
Thanks
