    booting from sd card

    Hi! Thank you for your answer! I think I haven't explained what I want to do very well. Those steps work for me for uploading the bitstream file and program the fpga. My problem is that I have quite a big project which cannot be integrated in bitstream file and what I my question is how to achieve this.

    But I want to store it on sd card, not on qspi flash. How can I store it ion micro sd?

    It is a big application for video processing over hdmi on Nexys Video. It also contains a Microblaze soft processor which must be programmed from Xilinx SDK. No, I don't even know ho to compress it. It managed to program the fpga with bistream file on sd, but I haven't managed to program the Microblaze from sd card.

    When I try to put it in bistream file, it fails because it is too big for bram. How can I add the code in dram from sdcard?
  5. Yes, it works. Thank you very much for your help!
  6. Thank you for your answer! From where should I change the I2C0 frequency? From Zynq7 block? Because I haven't found any option to modify the frequency of i2c there, but most probably, I don't know where to look exactly.
  7. Thank you for your time. Looking forward to receive a fix for it.
  8. I am using Zybo z7-20 board.
  9. Hi, I want to make a video processing ip on hdmi with Nexys Video. The hdmi signal will be generated by a Digilent Zybo board. I took the prebuilt images from petalinux repo for zybo. The Linux boots and display the terminal on a regulator monitor. Then, I connected the hdmi out from zybo to hdmi in port on nexys and monitor to nexys video hdmi out. For start, I just turned on the board with default configuratioin from qspi. The default configuration is a hdmi pass through because it works when I connect the input on nexys video to a raspberry pi. So, the monitor should display the terminal, but it doesn't. Taking a look at what dmesg prints, I've fount some interesting errors like: Registering SWP/SWPB emulation handler [ 1.068461] [drm] No max horizontal width in DT, using default 1920 [ 1.073394] [drm] No max vertical height in DT, using default 1080 [ 1.078249] OF: graph: no port node found in /amba_pl/xilinx_drm [ 1.082930] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

How could I fix it? On serial, the nexys video says : "Showing DVI input".
