Introduction
The BSP is based on Yocto Project-based BSP for Intel® Atom® Processors (Formerly Known as Elkhart Lake) on IoT Platforms of MR3 version. In particular, Yocto 3.1 (dunfell) with 5.15.21 LTS kernel are used. Although this BSP is an x86_64 distribution, it's also possible to run a 32-bit application since IA32 emulation feature is enabled in kernel.

| Wake On LAN is disabled by default. | To enable WoL, use the commands as follows.
# ethtool --change eno1 wol g # ethtool --change eno2 wol g The WoL setting will return to disabled after cold boot. |
| To protect critical process from Linux out-of-memory (OOM) killer | To make the process less likely to be killed by the OOM killer, you can do the following.
# echo -15 > /proc/$PID/oom_adj $PID is the process ID. You can set valid ranges for oom_adj from -16 to +15, and a setting of -17 exempts a process entirely from the OOM killer. The following command exempts X from the OOM killer. # pgrep -f "/usr/bin/X" | while read PID; do echo -17 > /proc/$PID/oom_adj; done |
