Problem in Flashing Boot from QSPI in ZEDBOARD

Question

Hello all,

I am quite new in hardware design. I am trying to boot a 8-bit shift-register topology written in VHDL from the QSPI memory of the Zedboard. Booting from SD card is successfully completed; but the problem is that I am not able to complete booting it from QSPI. Since the source is a VHDL code, it cannot be exported as a design and no .ELF files are being created. The guide that I used during the flashing process is "Zedboard_boot_guide_IDS141_1_v1_1.pdfu201D.

I'm sorry if there is a duplicate in the forum.

Thanks in advance for your help.

Hello Necati, The document you refer to is very dated and targets the older Xilinx ISE tool suite. I would suggest that you begin using the current Xilinx Vivado tool suite. The Zynq device on the ZedBoard is supported by the free WebPack Vivado version. That said I am a little confused about what you are trying to do. Creating a bootable image for either the SD Card or QSPI device requires a minimal Zynq PS (Processor System) design along with your PL (Programmable Logic) design. You would then export this to the SDK and generate an FSBL (First Stage Boot Loader), either a .bin file for SD Card boot or a .mcs file for QSPI boot. There is a good set of four tutorials that take you though this process posted on the MicroZed Reference Designs page. Tutorial 4 in particular details generating a bootable image. While it targets the MicroZed board you only need to change the board targeted to use with the ZedBoard: http://zedboard.org/support/design/1519/10 Adam Taylor also has a really good series of blog posts that detail designing with Zynq based boards: http://zedboard.org/content/microzed-chronicles -Gary
