  2. Hello, everyone. I am new here in this form and also with zybo. I have been working on one zybo project. I am finished with vivado design. but now I am working with the petalinux tool to create bootable sd card. I have read the tutorial to create a bootable image for Debian Jessie (it can boot perfectly). but I could not find proper materials to modify my devicetree file in order to work with VGA and other peripherals to make complete pc. can you please suggest me proper tutorials or articles? thank you
  3. hello -I created a petalinux project and I imported the "hw" description then builded BOOT.BIN -GOAL : booting linux on ZYBO and recognizing all the GPIOS where I will plug (GYRO, Accelerometre,Bleutooth,Leds,Buttons) -assuming that the Devitree is well configured and contains all of the GPIOS , the Petalinux RG Manual contains lots of options but I dont see at any of the steps that I should put the Devicetree alongside with BOOT.BIN and linux image in the FAT32 partition see image(1) below) RG manual link : -I'm following this type of SD card structure (see image(2) below) and I think this is the good way -PS : -I already configured the SD card in two partiton (FAT32 and ext4) -the ext4 partition contains a linario filesystem -I configured the RootFS type as "SD" in the petalinux project what should I do ?? THANK YOU FOR YOUR HELP.
