Segger System. View Realtime Analysis and Visualization for Free. RTOSOne of the most important aspects for developing complex realtime applications is get insights into what is going on the target. Segger just has released a free tool which gives an incredible useful insight view and visualization Segger System View for Free. RTOSSegger has announced the tool last week see https www. It works both bare metal no RTOS and with using an RTOS. The V2. 1. 0 release on the web page includes support for the Segger emb. OS. When I contacted Segger about the possibility to use it with Free. RTOS, they provided me with their first Free. RTOS port V2. 1. MANY THANKS, and I was able to get it quickly up and running and integrated both with Processor Expert and Kinetis SDK. The Segger System. Viewer is based on Segger RTT see Using Segger Real Time Terminal RTT with Eclipse all what it needs is a few functions on the target which communicate to the host over the Segger J Link debug connection. It is super fast and provides the ability to collect almost unlimited trace data. Tutorial. To make usage of RTT and System. View very easy for any Kinetis devices, I have created special Processor Expert components one for RTT and one for the System. View. I have it working well on ARM Cortex M4F.

ForgeThe easiest way is to use it with a Processor Expert project with or without the Kinetis SDK. You can enabledisable System. View for an existing project as well. Add the Segger. System. View component to the project it will addask for the Segger. RTT component too. Segger RTT and System. View Components. In my applications Im using the RTT channel 0 for consoleshellterminal communication. Therefore Im having two updown channels channel 0 for the terminal, and channel 1 for System. View. Segger RTT Configuration. In the Segger. System. View component I specify the channel I would like to use channel 1 in the example below, as Im using channel 0 for the terminal. I can specify an application name and device identification string. The RAM Base setting specifies the lowest RAM address. Segger System. View Settings. Finally, in the Free. RTOS component I enable the Segger System Viewer trace. This will add the necessary trace macros to the Kernel to write all the trace data information. Segger System View Trace Setting in Free.

TCB Segger System Viewer Application. The SEGGER System. Viewer has several views which give me insights what is going on. In the Events all the target events with the details are listed Events View. In the Timeline view I see the different task running over time Timeline view. In the CPU load view I see the CPU load in a realtime way CPU Load View.

To give you an example how useful that data is below is an application which has been stalled after a while because it was blocked by the USB stack after getting that information, I was able to implement a fix Problem with USB CDCThe problem was that the USB Send. Systemview Elanix' title='Systemview Elanix' />Data. Block method was waiting without a timeout as long as a transaction is going on. In the case of a USB communication problem, this results in a very long blocking time. The solution was to enable a timeout for the send operation Send. Data. Block USB Stack Timeout. With this, the Send. Data. Block would gracefully return for the case a transaction does not finish for whatever reason. CDC1Send. Data. Blockuint. Size. TMOUT1Counter. Handle timeout. uint.

Summary. Wow, Im really impressed The Segger System. View is a true treasure for any embedded developer it collects incredible useful data from a running system, free of charge. All what I need is a Segger J Link or a J Link enabled board. I plan to release the updated Segger RTT and Segger System. View support with the next Mcu. On. Eclipse component release. If you would like to receive the components in the current experimental state, drop me an email see About and Ill help you out. Otherwise simply clone my repostory on Git. Hub. Happy Viewing PS I would like to thank the company Segger for their support last week to get the Segger System. Viewer running with Free. RTOS Links. Related.
