Z-turn-Board-V2-Diary

Preliminary: Boot process: Outline:

Description

The z-turn board can be booted from either:

• the SD card
• or the QSPI (?) [onboard] flash

I’ll only cope with the first method, (I couldn’t find [external] access to the QSPI’s pins :’(..

Boot from the SD card:

• (Set the appropriate jumpers: J1:J2: OFF:ON)
• Create a FAT32 partition.
  • (TODO: FAT16, boot flag).
• Transfer the [generated] BOOT.bin.

Create the BOOT.bin file.

• This file will hold at least:
  • The FSBL[First stage boot loader] that will load the remaining parts, either into the PL or the PS unit.
    • (I.e., yes, :), the SD card will be used to program the FPGA).
• And any or both of the following:
  • The bitstream (for the FPGA)
  • The [PS] application part (e.g. a serial(USB) “Hellow World”).
    • (++Linux)

• Vivado:
  • (Block design)
    • (Zynq)
    • (Entity)
• Vitis:
  • (Platform)
    • (Our FPGA code along with the FSBL(Bootloader)
  • (Application)
    • (A [USB] “Hellow World” perhaps along with an FSBL(Bootloader))
• Vitis:
  • Boot image:
    • Partitions:
      • FSBL (either from the “Platform” or (perhaps (?)) from the “Application”)
      • bitstream (from the “Platform”)
      • elf (from the “Application”)
    • Creates a BOOT.bin
• Copy the boot image to an SD card (into a FAT32 partition)
