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

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:
+
=== Program the Quad-SPI NOR flash ===
−
* 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 ===
+
This chapter is compatible with [[BORA SOM | BORA]], [[BORA Xpress SOM | BORA Xpress]] and [[BORA Lite SOM | BORA Lite]] platforms, but below there is log for BORA Xpress SOM.
−
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 ====
+
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.
−
* 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:
 
  
−
<pre>
+
Then, boot the board with the microSD card and stop the automatic boot process of U-Boot in order to access the console.

Update to the latest u-boot version allows usage of u-boot environment variables available.

This chapter is compatible with [[BORA Lite SOM | BORA Lite]] SOM.

<pre class="workstation-terminal">
+
First of all, create a bootable microSD card as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project| here]] with <code>config_boralite_nand_usd</code> configuration file, and install <code>wic</code> binary on microSD. Then create artifact to install on NAND flash with <code>config_boralite_nand</code> configuration file, as described [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project| here]], and save the <code>BOOT.BIN</code> and <code>dave-image-devel-zynq-generic.tar.gz</code> artifact into the first partition of microSD.
−
=> run load
 
−
</pre>
 
  
−
=====fit image =====
+
In this case <code>BOOT.BIN</code> binary that came from to <code>config_boralite_nand_usd</code> and <code>config_boralite_nand</code> are different, so save it with different name. Alternatively you can download binaries from [https://mirror.dave.eu/desk-xz-l/ mirror] and install on microSD.
−
We assume that the following environment variables are present in u-boot:
 
  
−
<pre>
+
Then, install the following files into the microSD first partition:
−
loadk=tftpboot ${loadaddr} ${serverip}:${bootfile}
 
−
loadfdt=tftpboot ${fdtaddr} ${serverip}:${fdtfile}
 
−
spi_updatek=sf erase 200000 800000; sf write ${loadaddr} 200000 ${filesize}
 
−
spi_updatefdt=sf erase 180000 80000; sf write ${fdtaddr} 180000 ${filesize}
 
−
spi_loadk=sf read ${loadaddr} 200000 800000
 
−
spi_loadfdt=sf read ${fdtaddr} 180000 80000
 
−
spi_nand=sf probe; run spi_loadk spi_loadfdt nandargs addcons addmisc; if run configid_fixupfdt; then bootm ${loadaddr} - ${fdtaddr}; fi
 
−
</pre>
 
  
−
* Update the <code>bootfile</code> and <code>fdtfile</code> environment variables to fit the filename as found inside the TFTP server.
+
* <code>BOOT.BIN</code>. This binary come from to <code>config_boralite_nand_usd</code> configuration file, and need to install on microSD
−
* Program kernel and device tree on NOR flash with the following U-Boot command
+
* <code>boot.scr</code>
 +
* <code>desk-xz7-l-1.0.1_boralite_nand_BOOT.BIN.EXTENDED</code>. This binary come from to <code>config_boralite_nand</code> configuration file, and has to be installed on NAND flash

==== Program root file system into NAND flash ====

* Boot the system via SD or NFS as described in the e [[(<KIT>)#Quick_start_guide|Quick start guide]]

−
* By default, the NAND is already partitioned to allow booting from NAND-only (see next section) and, thus, some partitions are reserved for u-boot and kernel images. Here we won't modify this default configuration. The [[Memory Tecnology Device (MTD)|MTD]] partitions can be dumped with <code>/proc/mtd</code> (the partition's name should be self-explanatory)

Standalone boot[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, 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[edit | edit source]

This chapter is compatible with BORA, BORA Xpress and BORA Lite platforms, but below there is log for BORA Xpress SOM.

First of all, create a bootable microSD card as described here. Alternatively you can download binaries from mirror and install it on microSD or into tftpboot directory in your host device.

Then, boot the board with the microSD card and stop the automatic boot process of U-Boot in order to access the console.

Program the NAND flash[edit | edit source]

This chapter is compatible with BORA Lite SOM.

First of all, create a bootable microSD card as described here with config_boralite_nand_usd configuration file, and install wic binary on microSD. Then create artifact to install on NAND flash with config_boralite_nand configuration file, as described here, and save the BOOT.BIN and dave-image-devel-zynq-generic.tar.gz artifact into the first partition of microSD.

In this case BOOT.BIN binary that came from to config_boralite_nand_usd and config_boralite_nand are different, so save it with different name. Alternatively you can download binaries from mirror and install on microSD.

Then, install the following files into the microSD first partition:

  • BOOT.BIN. This binary come from to config_boralite_nand_usd configuration file, and need to install on microSD
  • boot.scr
  • desk-xz7-l-1.0.1_boralite_nand_BOOT.BIN.EXTENDED. This binary come from to config_boralite_nand configuration file, and has to be installed on NAND flash
  • desk-xz7-l-1.0.1_boralite_nand_dave-image-devel-zynq-generic.tar.gz
  • image.ub

Programming NAND flash from microSD[edit | edit source]

  • delete all partition on NAND flash memory

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