    Using Canbus on the Zynq 7000 board

    Hello, I have the Zynq 7000 board (Z-7010). I'm trying to build a Vhdl Program that receives a Canbus Frame. I saw in the tutorial that There is a builtin Canbus Controller, where is the canbus Interface?should i use the standard interface? Is there a simple example of such a program? - I use the 2017.1 Vivado and the Z-7010 Board. Thanks.

    Zybo I2c Master

    Hi, I have the Zybo Zynq 7000 board (Z-7010). I also have a Ti Msp430G2 launchpad. I need the Zybo to be the Master I2c , send request data from the Ti Chip. In Zybo i'm Using the I2c_0 Built in controller on the ps, i've tried the following Examples with no success(test failed Everytime): xiicps_polled_master_example.c xiicps_slave_monitor_example.c then i tried to to troubleshoot the problem, i'v used the xiicps_polled_slave_example.c and on the Ti Chip i used the wire library, as I2c Master and a c program that Scans Addresses - this works Therefor all the connections and vivado config are fine. How can find a working Master Program for zybo?

    Zybo I2C

    Hi, I have the Zybo Zynq 7000 board (Z-7010). I want to receive data from Multiple Devices via I2C protocol. In the PS there are 2 I2C Controllers. The Steps i made so far: 1) In vivado i created the ip : Zynq7 processing system. 2) i'v enables the I2C 0 controller and routed it to Emio. at this point i need 2 pins: clock and data, but instead i have 6 pins: where should i connect the pins? after Exploring this issue online i saw another option : using the Axi_IIc ip, With the same problem:

    Zynq 7000 intr_dme example

    Hi, I have the Zynq 7000 board (Z-7010). I'm trying to build a Vhdl Program that sends and basic Ethernet Frame throw the RJ45 onboard interface. I'm trying the Intr_Dma example to learn how to use the controllers on the PS. My block design is simply one block of Zynq7 Processing system with eth0 and UART1 enabled Exported the hardware to SDK and imported the example of emacps "xemacps_example_intr_dma.c". Run the program will show the following message from UART: "Entering into main() Error setup phy loopback" Debugging the program and I found the problem is inside function EmacPsUtilEnterLoopback of xemacps_example_util.c This function is to set the PHY chip to loopback mode. However, This functions only works for Marvell and TI chip. according to this great blog, this should work: http://igorfreire.com.br/blog/#zynq-ethernet-interface-zybo-board i'v tried troubleshooting this problem,i'v added the fallowing lines:(to the "EmacPsUtilEnterLoopback" function) printf("%d\n",PhyIdentity); printf("%d\n",PHY_ID_MARVELL); printf("%d\n",PHY_ID_TI); the output is: Entering into main() 28 321 8192 Error setup phy loopback Therefor the realtec phy has PhyIdentity of 28, marvell phy is 321 and Ti phy is 8192. i'v tried changing the following lines: if (PhyIdentity == 28) { printf("phy is Marvell\n"); Status = EmacPsUtilMarvellPhyLoopback(EmacPsInstancePtr, Speed, PhyAddr); } after it didnt work, i've tried this lines: if (PhyIdentity == 28) { printf("phy is TI\n"); Status = EmacPsUtilTiPhyLoopback(EmacPsInstancePtr, Speed, PhyAddr); Nothing works. where can i find the relevant code? Thanks, David

    Using the Rj45 and Ethernet controller

    Hello, I have the Zynq 7000 board (Z-7010). I'm trying to build a Vhdl Program that sends and basic Ethernet Frame throw the RJ45 onboard interface. so far i'v constructed the Frame itself according to the Ethernet IEEE 802.3 standard, now i see there are Gmii and Rgmii Interface and a builtin Phy controller but i cant understand how to use them all. Is there a simple example of such a program? - I use the 2017.1 Vivado and the Z-7010 Board. Thanks.

    Can't power up Zybo FPGA Board

    Hi, I just bought a Zybo FPGA Dev board from Digikey and tried to power it up using USB. But I cannot see any indication of whether the board is alive, i.e. LED (LD11) is not ON. The J7 is set for powering up via USB. I am quite new to this and would really appreciate some help. Thanks!
