We'll explain how to program and configure a <code>SOM</code> to boot in standalone mode, without the need for a system microSD card, with the following option:
 
−
* booting with Quad-SPI NOR
 
−
** in this configuration the primary boot images will be fetched from Quad-SPI NOR flash storage, while the root file system will be fetched from microSD
 
−
* booting with NAND
 
−
** in this configuration the primary boot images and rootfs will be fetched from NAND flash storage

=== Program the Quad-SPI NOR flash ===
+
We'll explain how to program and configure a <SOM> to boot in standalone mode, without the need for a system microSD card or an NFS server, with three options:
 +
* booting with SD only
 +
** in this configuration the whole system will boot without the need for a NOR/NAND flashes storage, all images and the root file system will be fetched from the SD card
 +
* booting with NOR and NAND internal storage
 +
** in this configuration the primary boot images will be fetched from NOR flash storage, while the root file system will be fetched from NAND flash
 +
 
 +
=== Program boot images into SD card ===
 +
The SD card should have at least 2 partition:
 +
* the first must be an FAT32 partition (type <code>b</code>) with size of at least 64MB
 +
* the second is a normal linux partition (type <code>83</code>) of at least 512M with ext3/ext4 filesystem
 +
 
 +
==== Create the SD card partitions ====
 +
* SD device has to be partitioned and properly formatted choosing the <code>file system</code> for each partition
 +
* an example of SD partitioning script is the following one (running on a DAVE Embedded Systems' DVDK VM):

First of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project#Petalinux_build | here]]. Alternatively you can download binaries from [https://mirror.dave.eu/desk-xz-l/ mirror] and install it on microSD or into <code>tftpboot</code> directory in your host device.
+
node=$1
  
−
Then, boot the board with the microSD card and stop the automatic boot process of U-Boot in order to access the console.

Standalone boot[edit | edit source]

Introduction[edit | edit source]

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


200px-Emblem-important.svg.png

The following programming examples are intended for laboratory usage or for preliminary deployment strategy.

A complete deployment strategy has to be carefully identifiyed taking into account the overall arguments like: boot speed, safe boot, recovery mechanisms, watchdog supervisor, etc.


We'll explain how to program and configure a <SOM> to boot in standalone mode, without the need for a system microSD card or an NFS server, with three options:

  • booting with SD only
    • in this configuration the whole system will boot without the need for a NOR/NAND flashes storage, all images and the root file system will be fetched from the SD card
  • booting with NOR and NAND internal storage
    • in this configuration the primary boot images will be fetched from NOR flash storage, while the root file system will be fetched from NAND flash

Program boot images into SD card[edit | edit source]

The SD card should have at least 2 partition:

  • the first must be an FAT32 partition (type b) with size of at least 64MB
  • the second is a normal linux partition (type 83) of at least 512M with ext3/ext4 filesystem

Create the SD card partitions[edit | edit source]

  • SD device has to be partitioned and properly formatted choosing the file system for each partition
  • an example of SD partitioning script is the following one (running on a DAVE Embedded Systems' DVDK VM):
#!/bin/sh

node=$1

# partition size in MB
RESERVED=8
BOOT_ROM_SIZE=128
RFS_SIZE=2048

# create the SDCARD partition
part=""
echo ${node} | grep mmcblk > /dev/null
if [ "$?" -eq "0" ]; then
        part="p"
fi

# print the SD total capacity
total_size=`sfdisk -s ${node}`
total_size=`expr ${total_size} / 1024`
echo SD total size: ${total_size}KB

# calculate partition sizes
boot_start=`expr ${RESERVED} \\* 1024 \\* 1024 / 512`
boot_size=`expr ${BOOT_ROM_SIZE} \\* 1024 \\* 1024 / 512`
rfs_start=`expr ${boot_size} + ${boot_start}`
rfs_size=`expr ${RFS_SIZE} \\* 1024 \\* 1024 / 512`

umount ${node}${part}1 > /dev/null 2>&1
umount ${node}${part}2 > /dev/null 2>&1

# call sfdisk to create partition table
{ echo ${boot_start},${boot_size},0c,-; echo ${rfs_start},${rfs_size},83,-; } | sfdisk --force ${node}

# format the SDCARD partition
echo "formatting boot"
mkfs.vfat -F 32 -n BOOT  ${node}${part}1
echo "formatting rfs"
mkfs.ext4 -F ${node}${part}2 -Lrfs

E.g. 

vdk@vagrant:~/desk-xz-l$ sudo ./sdcard-partition.sh /dev/sdc
SD total size: 7580KB
Checking that no-one is using this disk right now ... OK

Disk /dev/sdc: 7.41 GiB, 7948206080 bytes, 15523840 sectors
Disk model: STORAGE DEVICE  
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xd775a452

Old situation:

Device     Boot Start      End  Sectors  Size Id Type
/dev/sdc1        8192 15523839 15515648  7.4G  b W95 FAT32

>>> Created a new DOS disklabel with disk identifier 0x3f242b9b.
/dev/sdc1: Created a new partition 1 of type 'W95 FAT32 (LBA)' and of size 128 MiB.
/dev/sdc2: Created a new partition 2 of type 'Linux' and of size 2 GiB.
Partition #2 contains a ext4 signature.
/dev/sdc3: Done.

New situation:
Disklabel type: dos
Disk identifier: 0x3f242b9b

Device     Boot  Start     End Sectors  Size Id Type
/dev/sdc1        16384  278527  262144  128M  c W95 FAT32 (LBA)

dvdk@vagrant:~/desk-xz-l$

Then, insert the SD card in the target and boot the system via NFS as described in the e Booting from nfs guide

  • create a mount point and mount the first partition
root@bora:~# mkdir -p /mnt/sd
root@bora:~# mount /dev/mmcblk0p1 /mnt/sd
  • copy boot image files
root@bora:~# cp BOOT.BIN /mnt/sd
root@bora:~# cp image.ub /mnt/sd
root@bora:~# cp boot.scr /mnt/sd

Program root file system into SD card[edit | edit source]

  • mount the ext3/ext4 volume in the temporary directory
root@bora:~# mount /dev/mmcblk0p2 /mnt/ext
  • now, you can extract the root file system in the target directory
root@bora:~# tar zxpf images/linux/rootfs.tar.gz -C /mnt/ext
  • finally, you need to cleanly umount and safely reboot or turn off the system.
root@bora:~# umount /mnt/sd
root@bora:~# umount /mnt/ext
root@bora:~# reboot

Once restarted, the complete boot log can be like this one:

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

  • boot the system via NFS as described in the e Booting from nfs guide
  • the NAND is partitioned following the /proc/mtd scheme (the partition's name should be self-explanatory). See the MTD for more information on MTD layer.












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 mtd0, using UBI with:


ubiformat /dev/mtd0
ubiattach -m 0
ubimkvol /dev/ubi0 -N rootfs -m



E.g.



root@bora:~# ubiformat /dev/mtd0



  • mount the UBI volume using UBIFS in a temporary directory


mkdir -p /mnt/nand
mount -t ubifs ubi0_0 /mnt/nand



  • you can now extract the root file system into that directory


tar zxpf images/linux/rootfs.tar.gz -C /mnt/nand



  • finally, you need to cleanly umount and detach the MTD partition


umount /mnt/nand/
ubidetach -m 



You can now safely reboot or turn off the system.

In U-Boot environment check the following variable, which must contain the same MTD partition number used above



nand_args=setenv bootargs root=ubi0:rootfs rootfstype=ubifs rw ubi.mtd=0
