This article mainly introduces how to use EDR in Component, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

EDR, Error Detection and Reporting, a debugging mechanism added to Vx6 to monitor and record system errors

With this component included, VxWorks allocates an area at the top of memory where some system logs can be logged cyclically. This area will not be cleared during a system hot restart. These logs can be divided into various events: kernel, interrupt, process, etc.; and can be divided into different severity levels: fatal or warning, etc.

Several other functions are not commonly used, interested can try. edrClear() is used to clear these logs, otherwise when the storage area is full, the new log automatically overwrites the oldest log.

Users can also add hook functions to EDR that are automatically invoked when EDR generates logs

Write an example to see how it works.

This is exactly what:

New debug EDR, system log open plug-in.

A variety of records automatically added, the system restart is not afraid.
