  1. In order to find a workaround, I've tried to configure the project to source only the kernel from the Digilent repo, leaving uboot to the default "u-boot-plnx". With those settings, the build succeeds and the board is able to boot. However, the HDMI output does not work (no /dev/fb0). I've enabled the "Digilent VGA/HDMI DRM Encoder Driver" support from the kernel config, expanded the CMA pool, and copied the device tree "manual" settings from the "system-top.dts" file of the BSP project. Yet, I'm still missing the video output. Looking for a simple design I've done the same process starting from the hdmi_out design: https://github.com/Digilent/ZYBO/tree/master/Projects/hdmi_out Again, with no results...
  2. Hi @jpeyron, thank you for your answer. To double check, I repeated the process starting again from the linux_bd design but, this time, leaving the design untouched and I got the same error (blinking DONE LED). I suspect that, for some reason, the FSBL fail to configure the PL.
  3. Hi, I've built a custom design by adding some extra IPs to the diligent reference design for Petalinux: https://github.com/Digilent/ZYBO/tree/master/Projects/linux_bd Then I've created a new Petalinux project importing the hardware specification from the custom design. To include the software support for Digilent's IPs I've configured Petalinux in the same way as the reference bsp (including uboot and kernel sources from Digilent's git repo). https://github.com/Digilent/petalinux-bsps/tree/master/projects/Digilent-Zybo-Linux-BD-v2015.4 Then, in order to build petalinux, I need to add the CONFIG_SYS_MALLOC_F=y flag to the uboot configuration file. After this, the build process succeeded. However, if I try to boot the image from the SD card the "done" LD10 led start blinking and the boot fail. What I'm doing wrong? Thanks.
