  1. Hi @jpeyron, Thank you very much for your quick response - your fix worked like a charm! Best regards, Zhanneta
  2. Hello, I am working with Cora Z707S board and trying to get ethernet to work. Ethernet works only when using Petalinux provided by digilent (https://github.com/Digilent/Petalinux-Cora-Z7-07S) using the reset trick also provided by Digilent: "Ethernet PHY reset is not indicated in the device tree. This means it will not be used by the linux and u-boot drivers. This should not cause any problems at runtime, the reset is only used on boot. See commented device tree lines for how to enable. When uncommented, ethernet was not functional, likely due to a mismatch in the GPIO polarity." I would like to get the ethernet working when using SDK applications, any ideas? Is there an equivalent way of disabling reset from SDK application/bsp side like in device tree? Thank you, Zhanneta
  3. I figured out why it wasn't working...On Digilent github, it said to only copy _pre-built/linux/images/BOOT.BIN_ and _pre-built/linux/images/image.ub_ to the SD card. Instead, I copied all the files in the _pre-built/linux/images/ directory and the bitstream to the SD card. It's working now and I see the boot process in my UART terminal.
  4. Hello, I am trying to boot up linux on Cora Z707. I am using the base projects for Vivado (https://github.com/Digilent/Cora-Z7-07S-base-linux/) and petalinux (https://github.com/Digilent/Petalinux-Cora-Z7-07S/archive/v2017.4-1.zip) provided by Digilent. I followed the following steps: 0. Generate project and CD into the new project directory (petalinux-create -t project -s <path to .bsp file>) 1. Format microSD card to FAT filesystem partition (1 GB FAT32, 31 GB EXT4) 2. Copy _pre-built/linux/images/BOOT.BIN_ and _pre-built/linux/images/image.ub_ to the first partition of your SD card 3. Create a new file on the microSD card called uEnv.txt. Add the following line to the file, replacing the MAC address as found on the board's sticker, then save and close it: ethaddr=XX:XX:XX:XX:XX:XX 4. Eject the SD card from your computer and insert it into the Cora Z7 5. Short the MODE jumper (JP2) 6. Attach a power source and select it with JP3 (note that using USB for power may not provide sufficient current) 7. If not already done to provide power, attach a microUSB cable between the computer and the Cora Z7 8. Open a terminal program (Tera Term) and connect to the Cora Z7 with 115200/8/N/1 settings (and no Hardware flow control) 9. Press the SRST button to restart the Cora Z7. You should see the boot process at the terminal and eventually a root prompt. I got to step 9 and I am able to see Cora Z7 as one of my serial ports, but I don't see the boot process. Later I was able to get an SDK application running on Cora Z7 and I was able to see that over terminal with 921600 baudrate. What do you think is the issue with the terminal and boot process? Why am I not able to see it and log in into the system? Do you have any suggestions for tackling this issue? Thank you in advance for your help! Kindest regards, Zhanneta
  5. Jon, Thank you kindly for your help - everything worked just like you said! Best, Zhanneta
  6. Hello, I am trying to upgrade the base linux project (https://github.com/Digilent/Cora-Z7-07S-base-linux/) provided by Digilent to Vivado 2018.3 and I am having some issues. I followed the following steps: 1. Download and install Xilinx Vivado 2018.3 2. Install Digilent Board Files a. Download the archive of the vivado-boards Github repository and extract it wherever desired. b. Copy the contents of the folder called "new\board_files" to the board_files folder in the Vivado Installation directory (C:\Xilinx\Vivado\XXXX.X\data\boards\board_files) 3. Create base linux project in Vivado a. Download the archive of the Cora-Z7-07S-base-linux Github repository and extract it wherever desired. b. Edit code for Vivado 2018.3 (originally set up for Vivado 2016.4) i. Edit Vivado version in system_bd.tcl and system.hwh in src\bd\system\hw_handoff to say 2018.3 c. Open Vivado Tcl Shell and run command "source create_project.tcl" in directory "proj" i. Once project was loaded in Vivado, upgrade the ip cores by going to Reports->Report IP Status and upgrade all ip cores. I wasn't able to get pass the last step as 1 of the IP cores is not able to update. For pwm_rgb, it says that "IP definition is not found". Do you have any suggestions for tackling this issue?
