{{PageHeader|Writing system image to eMMC memory}} __toc__

This tutorial explains how to write the generated system image to the eMMC memory on the SpaceSOM-8Mplus module. This setup requires also the SpaceCB-8Mplus-ADV carrier board. The image is written using the UUU tool from NXP. It may be obtained from the NXP website or [https://github.com/NXPmicro/mfgtools github repository].

== Required files ==

In order to write the system image to the eMMC the following files are required (all of them are generated during Yocto system building):

* the bootloader binary - imx-boot-spacesom-8mplus-cb-sd.bin-flash_evk
* system image - somlabs-image-spacesom-8mplus-cb.wic

== Writing image procedure ==

The following steps are required to install the image in the eMMC memory.

* Connect the USB-C cable to the USB1 connector on the SpaceCB-8Mplus-ADV board
* Optionally connect the micro-USB cable to the JLink/Con connector and open a serial terminal to observe the u-boot logs during programming
* Connect both RCRV pins with a jumper to enable processor serial loader mode after power-up
* Power-on the board
* Run the UUU tool:

Linux:
<pre>
sudo ./uuu -v -b emmc_all imx-boot-spacesom-8mplus-cb-sd.bin-flash_evk somlabs-image-spacesom-8mplus-cb.wic
</pre>

Windows:
<pre>
uuu.exe -v -b emmc_all imx-boot-spacesom-8mplus-cb-sd.bin-flash_evk somlabs-image-spacesom-8mplus-cb.wic
</pre>
* Wait for the programming to finish
* Remove the jumper from RCRV pins
* Reset the board, the programmed system will boot
