Introduction[edit | edit source]

This document has been written and tested with the software/hardware combination described in the history table above. However it contains general concept that can be adapted on any DAVE Embedded Systems' Linux platform.

We'll explain how to program and configure a to boot in standalone mode, without the need of a system microSD card or a NFS server, with two options:

  • booting with NOR + NAND
    • U-Boot will fetch and program PL bitstream and then fetch Linux kernel binary images (kernel + device tree) from on-board NOR flash memory, while later the OS will mount the root file system from a NAND partition.

Use case #1[edit | edit source]

Program root file system in NAND flash[edit | edit source]

This is a common step for both booting options.

  • Boot the system via SD or NFS as described into the System boot and recovery via microSD card and Booting the system via NFS
  • By default, the NAND is already partitioned to allow booting from NAND-only (see next section) and, thus, some partitions are reserved for FSBL, U-boot and kernel images. Here we won't modify this default configuration. The MTD partitions can be dumped with /proc/mtd (the partition's name should be self-explanatory)


root@bora:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00080000 00020000 "nand-SPL"
mtd1: 00080000 00020000 "nand-uboot"
mtd2: 00040000 00020000 "nand-uboot-env1"
mtd3: 00040000 00020000 "nand-uboot-env2"
mtd4: 00440000 00020000 "nand-bitstream"
mtd5: 00040000 00020000 "nand-device-tree"
mtd6: 00400000 00020000 "nand-linux"
mtd7: 1f600000 00020000 "nand-rootfs"


200px-Emblem-important.svg.png

Please note that MTD partition index may change depending of flash device availability, flash device size, u-boot environment variables or kernel device driver load order. Always take care of looking inside /proc/mtd to match your specific layout


  • Format and initialize nand-ubi partition, which in our case is mtd7, using UBI with:
ubiformat /dev/mtd7
ubiattach -m 7
ubimkvol /dev/ubi0 -N rootfs -m

E.g. 

root@bora:~# ubiformat /dev/mtd7
ubiformat: mtd7 (nand), size 526385152 bytes (502.0 MiB), 4016 eraseblocks of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes

  • Now mount the UBI volume using UBIFS in a temporary directory
mkdir -p /mnt/nand
mount -t ubifs ubi0_0 /mnt/nand

E.g.: 

root@bora:~# mkdir -p /mnt/nand
root@bora:~# mount -t ubifs ubi0_0 /mnt/nand

  • you can now extract the root file system into that directory
tar zxvf belk-3.0.1_bora-image-devel-bora.tar.gz -C /mnt/nand
  • finally, you need to cleanly umount and detach the MTD partition
umount /mnt/nand/
ubidetach -m 7

E.g.

[  387.671411] UBI: detaching mtd7 from ubi0
[  387.677554] UBI: mtd7 is detached from ubi0

You can now safely reboot or turn off the system.

Program boot images[edit | edit source]

NOR flash[edit | edit source]

We assume that the following environment variables are present in u-boot: 

loadk=tftpboot ${loadaddr} ${bootfile}
loadfdt=tftpboot ${fdtaddr} ${fdtfile}
loadfpga=tftpboot ${loadaddr} ${fpgafile}
updatek=sf probe 0 0 0;sf erase ${kernel_base} +${filesize};sf write ${loadaddr} ${kernel_base} ${filesize}
updatefdt=sf probe 0 0 0;sf erase ${fdt_base} +${filesize};sf write ${fdtaddr} ${fdt_base} ${filesize}
updatefpga=sf probe 0 0 0;sf erase ${fpga_base} +${filesize};sf write ${loadaddr} ${fpga_base} ${filesize}
spi_loadk=sf read ${loadaddr} ${kernel_base} 0x800000
spi_loadfdt=sf read ${fdtaddr} ${fdt_base} 0x80000
spi_loadfpga=sf read ${loadaddr} ${fpga_base} 0x600000
program_fpga=run spi_loadfpga;fpga load 0 ${loadaddr} 0x5b3f0c
  • Update the bootfile, fdtfile and fpgafile environment variables to fit the filename as found inside the TFTP server.
  • Program kernel and device tree on NOR flash with the following U-Boot command
zynq-uboot> sf probe; run loadfpga updatefpga loadk updatek loadfdt updatefdt

E.g.: 

zynq-uboot> sf probe; run loadfpga updatefpga loadk updatek loadfdt updatefdt

In U-Boot environment please set the following variables in order to be able to boot from NOR + NAND 

nandargs=setenv bootargs ubi.mtd=7 root=ubi0_0 rootfstype=ubifs rw
spi_nand=sf probe; run program_fpga spi_loadk spi_loadfdt nandargs addcons addmisc; bootm ${loadaddr} - ${fdtaddr}


Reboot the system and configure U-Boot to apply the new configuration 

=> setenv bootcmd run spi_nand
=> saveenv
