SD card image for picozed SDR

Question

Hi,

My monitor can not display anything 50 seconds later after the board was powered on, and the monitor was connected with board correctly, and it can work well when connected with PC.

when board was powered on:

DS 1:on

DS 8:on

DS 4:on ,3 seconds later off

The SD card contains both a FAT32 partition visible on a Windows PC, and an EXT4 partition visible to Linux. You over-wrote the original Analog Devices image shipped with the kit when configuring the SD card through MathWorks tools. When you subsequently copied back the folder structure from your Windows PC, only the FAT32 files came back, while EXT4 were left with MathWorks files. Consequently the SD card contained a mix of Analog Devices FAT32 and MathWorks EXT4 and PicoZed SDR cannot boot. At this point you need to completely restore the SD card to the Analog Devices image: https://wiki.analog.com/resources/tools-software/linux-software/zynq_images Some more background: MathWorks SD card image for PicoZed SDR using Communications System Toolbox Support Package for Xilinx Zynq-Based Radio is meant for radio-in-the-loop realtime data capture to Simulink, and targetting (HDL code generation) using HDL Workflow Advisor to a Vivado project. http://www.mathworks.com/help/supportpkg/xilinxzynqbasedradio/index.html Analog Devices uses a Linux kernel with driver for the ADV7511 HDMI chip to display UBUNTU desktop. MathWorks uses a different Linux kernel not meant for stand-alone Linux desktop.
