  1. Hello I'm using PYNQ-Z1 board. I am trying to receive CAN traffic with PmodCAN on the board. Here is my Block Design. Then, Generate Bitstream was successful. (But some warnings appeared and the messages are like Generate_Bitstream_messagex.png) I did Export Hardwear and Launch SDK. When I created the Hello world project in SDK and compiled it, there was no problem. However, as soon as I executed Program FPGA, the following error message appeared. How can I fix this error? ---------------------------------------------------------------------------------------------------------------------------- bitstream is not compatible with the target Program FPGA failed bitstream is not compatible with the target ---------------------------------------------------------------------------------------------------------------------------- By the way, the PmodCAN wiki page says that it is necessary to send SPI commands to set up PmodCAN. Do I have to do this setup when sending and receiving CAN messages on the PYNQ board? https://reference.digilentinc.com/reference/pmod/pmodcan/reference-manual
  2. Hello all, I am trying to set up a CAN communication between a ZYBO Z7 Board with a PmodCAN Controller (connected on JE) and a Raspberry PI 3 using a Niren CAN Module as Controller. Letting 2 Raspberries communicating which each other via SocketCAN works fine, both can send and receive CAN data. Now if I try to let the Zybo communicate with the Raspberry using the example codes for transmit and receive data there seems to be no data on the bus. Neither the Zybo receives any data from the RPi nor the RPi from the Zybo. I have created a block design and tried the example codes according to the guide from the digilentinc website here . The LoopBack example does work as intended, Tera Term shows the messages being send, fetched and received. Just when I try to send data from the RPi the Zybo waits endlessly and any data send out from the Zybo wont be caught by the RPi. I have tried different bitrates to no avail. Any help or directing towards the right path in case i am way off in what i am trying is greatly appreciated. The block design is attached. Cheers
