==Introduction==
 
−
Mito8M is the first DAVE Embedded Systems' product based on a core implementing the [https://en.wikipedia.org/wiki/ARM_architecture#64/32-bit_architecture ARMv8-A] architecture.
 
−
Specifically, it is built upon the [https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8m-family-armcortex-a53-cortex-m4-audio-voice-video:i.MX8M NXP i.MX8M] system-on-chip (SoC).
 
  
−
This Technical Note (TN) describes how to run [https://www.armbian.com Armbian Buster] distribution on this platform. For the sake of completeness, it is worth remembering that Armbian Buster is based on Debian 10.
+
==Results==
 +
This section details the results that were achieved by the different benchmarks
  
−
==Testbed==
+
===General configuration===
−
To a good extent, '''Mito8M is electrically and mechanically compatible with [[:Category:AxelLite|Axel Lite]]'''. For this reason, the testbed used for this TN is pretty similar to the one described [[SBCX-TN-004:_Running_Armbian_Buster_(Debian_10)|here]]. Even though the SBCX carrier board is designed to host Axel Lite, in fact, '''it supports Mito8M as well'''.
+
This section illustrates the cofiguration settings common to all the tests performed.

Apart from the SoM, the most relevant difference with SBCX-TN-004 is related to the root file system. In this case, it was built for the <code>aarch64</code> architecture.
+
GCC
−
 
 
−
The root file system was stored on a partition of the microSD card inserted in the slot J26. This partition is associated with the <code>/dev/mmcblk1p2</code> device file:
