Getting started with custom VHDL and Linux

Former Member

Hello all,
I'm just getting started with a zedboard where I have to write some application software. So I'm fine with using the standard Linux that comes with it. But the thing is that our electronics guy has to write a custom VHDL for it.

What does he need to give me exactly to put on the card ? A boot.bin and a dts file ? Is that all ?

So after I convert the dts to dtd, all I need to have on the card is:
System.map
boot.bin
devicetree.dtb
uImage
uramdisk.image.gz

Is that correct or do I need to recreate the files (System.map, uImage, uramdisk) as well ?
Thanks

    Hi dargaud,

    Inside that BIF example, as you mentioned, they do not mention where the bitstream file (in your case system.bit) gets inserted.

    The bistream should be inserted between the FSBL image and the first user executable (in your case it is uboot.elf) so the Boot Image Format (BIF) listing would look like this:

    image : {
      [bootloader]fsbl.elf
      system.bit
      u-boot.elf   [load=0x2a00000]
      devicetree.dtb [load=0x2000000]
      uramdisk.image.gz [load=0x3000000]
      uImage.bin // currently bootgen requires a file extension. this is just a renamed uImage }

    Then you can use that BIF to create a boot image containing your bitstream and the other pieces needed to boot Linux.

    Regards,
