  1. Hello All, I have a Coraz7-10 board where I have the uart working in send mode, but not in receive mode. The uart is configured to operate on an interrupt, and I'm using the xilinx example code. I have modified just slightly with some debug messages and the recv handler. Basically, I just want to "set" a signal when then handler occurs, and "reset" it in the main() loop. In the handler itself, I am just checking to see if the received data makes it there, confirming in debugger view of SDK with watch variables. However, rx data is never present. I'm new to Zync, so if ther
  2. Hej, I try to configure the zynq7 PS in vivado 19.2 but the used board Cora Z7 is not available in the "Presets List". see screen dump. The board is selectable when I set up a new project. I tried to import xps settings and addressed the file preset.xml directly from C:\Xilinx\Vivado\2019.2\data\boards\board_files\cora-z7-10\B.0 but "Current Preset: none" What to do to preset the zynq PS for Cora Z7?
  3. Hi, I've opened the Cora-Z7-10-base-linux project in Vivado 2017.4 (to avoid any version-dependent issues) on Linux, and I was hoping to be able to route the UART 1 device from the ZYNQ7 Processing System out to the outside world. Ideally I'd like it to be wired up to the DP0 and DP1 pins, as I have a nice little Arduino Click2 adapter that I can put an RS485 Click board one. However, being very new to all this Zynq/Cora/Vivado stuff, I'm not sure how to do it. I started off (with a bit of advice from someone who knows more about this than me, but was rushing off home!) by openi
  4. Hello everyone! I'm trying to install Petalinux on a Cora Z7-10 I followed all the steps described here: github.com/Digilent/Petalinux-Cora-Z7-10 but when I try to boot it I get this message: hwclock: can't open '/dev/misc/rtc': no such file or directory after this, I can't write anything in Minicom. As in my folder /dev didn't have the misc folder, following some advice that I found on the net I created the folder and first tried to soft-link /dev/rtc0 and then hard-link it also but none of those worked, I still get the same error. Did anyone go through the same issue
  5. I'm just starting out with the CoraZ7-10 and having what seems like a weird issue. I've followed the getting started stuff at https://github.com/Digilent/Petalinux-Cora-Z7-10 to the letter and packaged up a BOOT.bin and image.ub that loads and boots fine. I now want to try a simple custom application, so followed the instructions to the letter in the section "Creating and Adding Custom Applications" (for a C++ app) in the Petalinux reference guide for 2017.4 (https://www.xilinx.com/support/documentation/sw_manuals/xilinx2017_4/ug1144-petalinux-tools-reference-guide.pdf), followed by the "
  6. Hello, Can the differential input xadc pins A6-A11 of cora z7-10 take input range -0.5v to +0.5v instead of 0v to 1v? In Cora z7-10 reference manual it is stated that it can take input voltage range from 0v to 1v but i have worked in zybo board's XADC which could take differential ADC input voltage from -0.5v to +0.5v. Could anyone clarify on the range of input volatges for differential XADC on CORA z7-10 Board? Thank You.
