  1. Hi @jpeyron I have an open case with PE on this Issue , but i see on my scope that the send valid msgs, just not like the official protocol , i should be able to see the raw data on the Zybo. I also have an open case with Microchip , maybe then can help. is there anything else i can do until they answer?
  2. Hi @jpeyron these are the facts untill now: the pe3 ECU sends canbus data like it should on its datasheet but the format isnt exactly like in formal protocol. the msg it sends can be seen a few posts ago. when the pmod is on listen only mode - i have corrupted data , and the pmod doesnt sent ack so the ECU sends the same msg all the time. when the pmod is on normal mode - i have no data received("Error, message not received") I thought that the reason is that the msp25625 drops the frame for error. that why i changed the CAN_RXB0CTRL_REG data to 0x0 istead o
  3. Hi @jpeyron In the Code there is a reg that determines the baud rate - how can i change the baud rate to be fixed? and what could cause the raw data from the canbus to be wrong? the baud rate only?
  4. Hi @jpeyron i've connected the PE3 ECU to the agilent keysight oscilloscope, what i see is that the ECU sends the data like it should(according to the document attached) the ECU sent one msg all the time: ID Type DLC Data CRC 0CFFF048 Data 8.00 00 00 00 00 00 00 00 00 12000.00 0CFFF048 Data 8.00 00 00 00 00 00 00 00 00 12000.00 all of the data from the scope is attached. how should i proceed? t
  5. Hi @jpeyron, I found the reason why it didnt work, the following command isnt working with "CAN_ModeNormalOperation", it works only with "CAN_ModeListenOnly" for some reason: void CanBusInitialize() { EnableCaches(); CAN_begin(&myDevice, XPAR_PMODCAN_0_AXI_LITE_GPIO_BASEADDR, XPAR_PMODCAN_0_AXI_LITE_SPI_BASEADDR); CAN_Configure(&myDevice, CAN_ModeListenOnly); } anyway, now i have another problem, when i connect to the PE3 ECU, i get the following Raw Data: j1939 standart - 500 Kb/S: 3FD3CD1533A43BD7ECE2 3FD37C1533A43BD7ECE2
  6. i've finally tried the loopback program - it seems to work - the output:
  7. jon - i've tried all the speeds available in the ECU including 500 Kbps, about the loopback - i'll do it soon and update. noterobot - i'm using PE3 ECU, that works with the SAE J1939 standard.
  8. Hi @jpeyron, i've tried all 4 options: only jp1 on only jp2 on jp1 and jp2 on, both of them off(jumper not connected) when i remove the Pmod, i get status FF. when its connected my status is always 0. Thanks, David
  9. I connected the CanH and CanL to the Blue connector(J3), and the ground of the ECU to the ground on J3. i've used the following config: three commands set a CAN speed of 250 kBPS with a CAN clock of 20 MHz. CNF1 (0x2A) set to 0x41 CNF2 (0x29) set to 0xFB CNF3 (0x28) set to 0x86 then i configured the ECU Canbus messages speed to 250kBps. what can i check/do? Thanks, David
  10. Hi @jpeyron I bought the Pmod CAN from Digilent. I've followed all the Installation Steps, and i should have a working code. I'm Trying to receive Data from the PE3 ECU, that works with the SAE J1939 standard (http://pe-ltd.com/assets/AN400_CAN_Protocol_C.pdf). When i Use the Example code(Receive only - Author: @artvvb - ) provided with the Pmod Can. I always get Status = 0. When i Connect the PE3 to a Scope, i can see that is sends the Canbus Messages. In the Pmod CAN notes i see that it only Compatible with ISO-11898-1, ISO-11898-2, and ISO-11898-5 What s

    Heat Sink for Zybo

    Hi @jpeyron, is there a on board sensor on the zynq main chip that measure the temp and shuts down the system if overheated? If my chip works at 100% cpu and a few more medium size vhdl programs for 5 hours every time, should i add heat sink? thanks,

    Zybo I2c Master

    jpeyron Thank you for your replay, Where can i find the C code for Zybo communicating with this Pmod? i only see the code for "Library and example code for a microcontroller using the Arduino IDE" 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 al

    Zybo I2C

    After reading other posts online and your answer, i saw that the 6 ports are already connected , and i only need to make the IIC_0 port external. After the IIC_o port is external you should go to I/0 ports , then there are only 2 ports of IIC , then you choose the restrictions as described in the following post: IIC how to vivado

    Zybo I2C

    Thank you for the response, I'm having trouble understanding the connection that should be made in vivado: should i use the emio port to the iic controller or the AXI_iic, and which of the ports are data and clock?(I have 6 ports). i already found the code examples in SDK, i just need help to make the connection in vivado. as for the PmodRTCC , they use an existing IP called PmodRTCC_v1_0 in order to connect it to the PMOD.

    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:
  17. 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
  18. 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.
  19. 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.

    booting from QSPI

    Hello, I have the Zynq 7000 board (Z-7010), i have built a basic led counting program in Vhdl. I'm trying to make this program boot by itself without Vivado. I'v found a few ref guides on this site and other sites and preformed this steps: 1. Open "Bitstream Settings", check "-bin_file*" checkbox and click OK. 2. Click on "Generate Bitstream" to generate your bit and bin file. 3. Open "Hardware Manager -> Open Target -> Open New Target..." 4. Add your memory. For this, right click on device (xc7a35t_0) -> Add Configuration Memory Device -> write
