 Edit run_mmc.sh, this is a script stored on the micro sd card that is run when the camera boots.  You can change the hostname of the camera, mount NFS, add ping commands, anything you like.

 Connectivity is supported using a direct USB connection only... this means a single cable from the camera, to a supported host (An OpenWRT router, for example) that supports the usb-cdc-ncm specification. (NCM, not ECM) If you have an OpenWrt based router, install the ```kmod-usb-net-cdc-ncm``` package.  The camera should automatically pull the IP from the router with most configurations.  You can also use any modern linux distro to provide internet to the camera, provided it supports CDC_NCM.  enjoy!

+When USB Direct connectivity is enabled, the camera will be unable to communicate with accessories.  To enable remote spotlight accessory support, enable the following variable and set the IP Address of the host as follows:
+```
+REMOTE_SPOTLIGHT="true"
 
+REMOTE_SPOTLIGHT_HOST="0.0.0.0"
+```
+
+Then, run the following command on the host where the spotlight is attached to:
+
+```
+socat TCP4-LISTEN:9000,reuseaddr,fork /dev/ttyUSB0,raw,echo=0
+```
+
+Change ```/dev/ttyUSB0``` to whatever path your spotlight enumerated to if necessary.  The camera will now be able to control the spotlight.

 ## Latest Updates
 
+* 04-17-22:  Add remote spotlight accessory capability
 * 04-15-22:  Enable USB Direct functionality. Allows you to connect camera using a USB cable to a device supporting CDC_NCM devices to get an internet connection, no USB Ethernet Adapter required.  
 * 04-14-22:  Fix kernel command line memory mappings, resolves stability issues
 * 04-14-22:  Possible memory leak with some USB adapters used, added 128MB swap file and logic as workaround to prevent oom killing
 * 04-13-22:  Firmware updates are disabled by default, there is a bug in the bootloader that corrupts the kernel partition requiring the re-flash of the camera if an update is processed and the memory card is removed before next boot.  The bootloader proceeds to copy the partitions and the system will not boot unless re-flashed.  pending investigation.
 * 04-12-22:  Updated, custom kernel loads all required items from micro sd card.  System modification no longer needed.
-* 04-05-22:  Update readme to indicate that telnet mod nor DNS spoofing is required for installation, and add pre-requisites section.
