[Trainings available on Ethernet comms]

Hi,

 

Q1. Need some help if there are any available courses paid/unpaid regarding Ethernet communication on Zynq-7000 SoC. 

Q2: Solution to below problem statement:

 Working on a project, where we want Zynq-7000 FPGA (we are using Cora z7-10 development board) need to be integrated with one of the applications on the laptop. We are using an Ethernet-based protocol for communication.

Here we have written Logic using VHDL in PL part of Zynq-7000. Using Zynq processing system and AXI interconnect we are integrating PL and PS.

Now, once the bits stream is generated, SDK is launched. Here we want to understand how we can achieve Ethernet communication (full duplex) using embedded C code to successfully transfer our logic built-in PL part to targetted application and receive information from the application to Zynq FPGA.

 

Thanks,

Mukta

[Communication between Cora-z7 and HMi]

Hi,

We are trying to communicate cora-z7 FPGA Board to HMI for which we need to implement Modbus RTU.

Can you help us in implementing Modbus RTU? Whether it involve only FPGA or both FPGA and processor?

 

Thanks,

Mukta

[Using ARTY A7 with PMOD RS232]

It says other pair of differential pin should be made ground to make other pin of pair as single ended. But in case I connect PMOD RS232 directly to high speed pmod, does that work? 

[Using ARTY A7 with PMOD RS232]

Hello,

Can I connect high speed pmod connector present on cora z7-10 FPGA board to PMOD RS232 converter board? Since high speed pmod has differential I/O pins.

[PL Configuration via Ethernet]

In example application, driver related to ethernet includes options for either TI or Marvell PHY chip. Since Realtek PHY is used on board, do we need to write driver for them as well?

[PL Configuration via Ethernet]

PHY used in Cora-Z7 is Realtek (RTL8211E-VL), do we need to write drivers in order to implement Ethernet controller in SDK? Since I'm a beginner, I need to know how to implement Ethernet controller using Realtek PHY in windows OS.

• What Ethernet PHY are you using?
• Are you connecting the PHY to a PS MAC through the EMIO?
• What kind of Ethernet speed do you expect to use?

• Ethernet PHY:  onboard Realtek RTL8211E-VL.
• No. It is connected to MIO Bank 501
• Preferably 1Gbps. 100Mbps will works fine.

 

[PL Configuration via Ethernet]

I'm using Cora Z7 FPGA board which has Zynq 7000  SoC. I have written logic in VHDL. I need to send signal data from PL to PC via Ethernet and also receive data from PC to PL of FPGA Board via Ethernet (received data from PC should be used in VHDL code to perform some calculations.) 

Inputs and outputs of VHDL code are assigned to I/O's of board. How to transfer data from PL to PC and vice versa? 

 

Thanks,

Mukta
