  1. I have gone through the Digilent Zybo Z7-20 Petalinux BSP Project here: https://github.com/Digilent/Petalinux-Zybo-Z7-20/releases/tag/v2017.4-3 And have used it to successfully build the project, including with modificatons described to create a SD based system with full development system based on a Ubuntu userland. There is only one mystery I have so far never solved - the file package includes a bitstream in images/linux/system_wrapper.bit which is included in all the example "petalinux-package" commands, but I have no idea where this bitstream came from or what functionalit
  2. That looks much clearer with the 'alternate build' and note which follows it. I assume it is the section starting from the title 'Build the petalinux project' which could have a 'default ram rootfs configuration' subheading. Regards, Digby.
  3. Thanks Vicentiu, That had occured to me, without help I probably would have ended up reinstalling to try it. The Petalinux-Zybo-Z7-20/README.md file that I was following (as presumably would anyone trying to put Linux on a digilent board for the first time) makes no mention of the possibility of running petalinux-config (is that what you mean by 'rootfs config'?) until a petalinux-build has already been performed, and I wasn't planning to deviate from a slavish step by step following of the instructions on my first attempt to get something running. So I still think a small update to tha
  4. Thanks - this solution worked for me. I had exactly the same issue trying to install Linux on a ZYBO Z7 ZYNC-7020 board, working through the instructions in Petalinux-Zybo-Z7-20/README.md (Zybo Z7-20 Petalinux BSP Project). I assume there is some documentation somewhere for the tools installed by the petalinux installer, but I have not yet found anything that mentions the '-x mrproper' build cleaning option, so I think this probably should be added to the above mentioned document. Don't know how anyone would get the SD rootfs section working without this step.
