PetaLinux SD boot

Former Member

I'm having trouble figuring out how to get the image I've created for the microZed 7020 to boot on it. It runs nicely in the qemu emulator but I can't get a valid system.bit.bin file. I've found some not quiet for microZed instructions to make a .bit.bin file, but I try using any of those files the boot process ends with a timeout on DMA when trying to load the FMGA.

For reference I'm using the Avnet-MicroZed-z7020-v2014.2.bsp file with the petalinux-create command, that appears to be the most correct one to use.

With a system.bit.bin that I made using "bootgen -image test.bif -split bin -o i BOOT.BIN" but none of the .bit files I could find to convert with that matched the instructions so I think I'm doing something wrong there. But the boot attempts with that system.bit.bin all failed with:

fpga - loadable FPGA image support

Usage:
fpga [operation type] [device number] [image address] [image size]
fpga operations:
  dump  [dev]                   Load device to memory buffer
  info  [dev]                   list known device information
  load  [dev] [address] [size]  Load device from memory buffer
  loadb [dev] [address] [size]  Load device from bitstream buffer (Xilinx only)
  loadmk [dev] [address]        Load device generated with mkimage
        For loadmk operating on FIT format uImage address must include
        subimage unit name in the form of addr:<subimg_uname>

Really I'm hoping someone just points me to the correct instructions for this.

    So I was wondering if the "MicroZed 7020 Open Source Linux In System QSPI Programming Tutorial" as mentioned in the other thread was what was poisoning the U-Boot env variabels, so I did the full wipe as described in the other thread then put the boot.bin created by the command you posted (petalinux-package ...) on a sd card and set the jumpers to boot from the SD card.

    Nothing happens, not a single character is printed to the terminal.



    While trying to think of things to get this all working I noticed I hadn't gone through the 4 tutorials (01_MicroZed_Zynq_Intro_2014_2_01 to 04_MicroZed_FSBL_Boot_2014_2_01) which I just did (except for the JTAG bits, not a piece of hardware we have lying around conveniently right now) and all of those worked fine.


    As to what my end goal is:
    We want linux on the mircoZed with a few applications of our writing doing their thing. The petaLinux flow of things looks really nice and reliable. As yet I'm not wanting to anything a non-standard way, I've gone as far as using a centos VM inside my Ubuntu box because of some issues running petalinux in ubuntu.


    So I'm currently wondering:
    A) What is the correct way to make those three precursor files?
    B) Is there meant to be any files along side the BOOT.BIN file on the SD card for booting from SD card?
