DESK-MX6-L/Deployment/Standalone boot

→‎Standalone boot
=== Program boot images into NOR flash ===
 
It is supposed tat the proper filenames are configured on u-boot variables. In the following examples, we use the boot images:
 
<pre>
spl=desk-mx-l/SPL
ubootimg=desk-mx-l/u-boot.img
bootfile=desk-mx-l/uImage
fdtfile=desk-mx-l/imx6q-sbcx-cb0012.dtb
</pre>
 
We assume that the following environment variables are present in u-boot too:
 
<pre>
load_spl=tftp ${loadaddr} ${spl}
load_uboot=tftp ${loaddr} ${ubootimg}
spi_update_spl=sf probe; sf erase 0 10000;sf write ${loadaddr} 400 ${filesize}
spi_update_uboot=sf probe; sf erase 10000 f0000;sf write ${loadaddr} 10000 ${filesize}
</pre>

====u-Boot====
u-boot SPL on NAND flash must be programmed using NXP <code>kobs-ng</code> utilityand the second stage using the <code>nandwrite</code>: this tool is required for writing the correct u-boot image on NAND storing all information needed by bootrom to identify the NAND as a boot device.
Here below an example:
* uses a rfs with <b>kobs-ng</b> utility available on it (e.g. DAVE's rfs provided with <KIT>)
* copy the related u-boot imx image file on nfs /home/root (for example)
* execute ''kobs-ng '' passing the parameters for flashing u-boot on NAND* erase and program the second stage using ''flash_erase'' and ''nandwrite''

* 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)
