  1. I decided to bite the bullet and use the Digilent BSP and Petalinux 2017.4. It was easier than I anticipated. My app uses openamp, and all of the accesses to the programmable fabric are done through the baremetal firmware running on processor #1. So the only device tree modifications to the Digilent BSP were the ones that make the echo-test app work. I didn't even change the location of the shared memory area, since the address on the Zybo version (0x3e000000) aliases down to 0x1e000000, which works perfectly. I wish everything were ported to 2018.2, but I appreciate that keeping all of you boards current with all of the Xilinx tools and updates is a significant chunk of work! Mike Boich
  2. I'm trying to migrate a project from the Zybo Z7 to Cora Z7-10. For the Zybo, I was able to use my own Vivado project (which included the TTC and other required elements), and then create a project in petalinux using the zynq template, do a "petalinux-config --get-hw-description <my-design>, build, package, and boot from the resulting SD card. When I try the same thing on the Cora it fails. (Doesn't even get as far as loading my FPGA bitstream). I can get the Digilent Cora BSP package to boot, but that appears to require that I use Petalinux 2017.4, and all the work I've done to date is on 2018.2. Is there some difference between the Cora and the Zybo that would explain why I'm having problems, or am I doing something wrong? thx Mike Boich
  3. Thanks Jon. I decided to just create a new project with the custom hardware that I need (including the linux requirements like TTC, etc.), and was able to get through the workflow and produce a working kernel. Now I'm making my way through the UIO stuff! Mike
  4. I'm have a project up and running on bare-metal, and want to put it on top of embedded linux. I'm assuming I should start with your base hw configuration and that add my custom hardware to that, but I'm having trouble getting Vivado to open the project. I assume that I need to use Petalinux 2017.4 and Vivado 2017.4, since those are the tool versions that were used to create your base config. I've cloned the Zybo-Z7-20-base-linux project folder. I then to try to invoke Vivado with the "create_project.tcl" script as a command-line argument, and I get an error. The error is: "ERROR: [ProjectBase 63-9] XML parser encountered a problem in /home/mike/peta_world/ Zybo-Z7-20-base-linux/proj/create_project.tcl at line 1 : XML character encoding not supported". Any idea what causes this? Thanks in advance for any help you can give me. - Mike
