To overcome this problem, a reset supervisor circuit can be used. The two documents must be used in conjunction to utilize them fully. An on-board oscillator in the AM generates the base clock and subsequent module clocks as needed within the AM processor. By communicating over the I2C bus, these outputs can be set to arbitrary values. L3 map is not of much use to the developer while DDR map is dynamic and is part of the application.
Retrieved from ” http: Modify the ethPrioQueue value as per requirement. All the LEDs are green in color.
Other applications might have their own map. Queue 0 high priority queue is reserved as the real-time queue. To change how ttm packets are accepted or rejected change the value in the structure. Most often Storm Prevention is the main reason for users not being able to receive a packet, esp if the rate is configured incorrectly. This can be done by.

A brief summary is provided below to explain where the data is copied to, how and why. The actual capacity may be lower owing to collisions. This page was last modified on 6 Februaryat TI generally provides two types of resets: Forwarding Qm335x specify how packets are forwarded between ports and from the port rtm the Host.
I2C address of the trk is configured as The built-in debouncing time defines a minimum button press duration that is required for button press detection. But these map to the same interrupt and ISR per port i. To quickly verify if the logic is indeed dropping packets, try sending some broadcast packets at line rate to the device and check the value of PRU statistics variable stormPrevCounter. It has X pixels and supports up to For technical support please post your questions at aam335x The Pin assignment is as given below.
For time critical applications with low latency requirements directly calling the API’s is recommended. Developers are requested to consult the API guide and other relevant user guides for exact coding details. The LLD expects single interrupt for both Ports.

Please note as of Wednesday, August 15th, this wiki has been set to read only. This article builds upon the foundation outlined in it. Refer to the API section of Learning for more details. This is where the actual packet buffers or queues are located. As of now the multicast and broadcast storm prevention functionalities are clubbed together but it is proposed to have them separate in the future.
Queue 1 and Queue 3 are high priority queues for Port 1 and Port 2 respectively. TTS reduces the transmission jitter from 10us range to 40ns. It is internally configured as a16 Meg x 16 x 8 bank memory.
The task itself is a simple function with two arguments.
