zynq ps and conventional miccroprocessor

[Arjun]

hello everyone , 

i am working zynq zybo ,, can anyone please tell me what is the difference between zynq processing system and conventional microprocessor

Hello @Arjun,

A conventional microprocessor is an IC which has only the CPU inside, without RAM, ROM, or any others peripherals. If you check this link on page 5 :http://www.ioe.nchu.edu.tw/Pic/CourseItem/4468_20_Zynq_Architecture.pdf you will found out that, aside the dual arm cortex processor, the processing system of the Zynq architecture has a lots of other peripherals.

Hi @Arjun,

We do not have a demo/tutorial for using the ethernet other than the echo server as shown here. In the Vivado/SDK 2018.2 there are multiple LWiP applications that look like a good place to start. There is a known issue with Vivado/SDK 2018.2 dealing with the xadapter.c that is discussed and has a solution here.

cheers,

Jon
