		<description><![CDATA[I&#8217;ve been accessing the Hava console via it&#8217;s serial port for quite a while.  It requires an adapter that converts the Hava&#8217;s 3.3 volt serial to something a pc can talk to.  This allowed me to get root access to the Hava Titanium and poke around in it&#8217;s firmware. It&#8217;s also possible to access the [...]]]></description>

		<description><![CDATA[The Hava Titanium HD has a logic level serial console available on J21. The logic level is 3.3 volts. Only three wires are needed, pins 1, 4, and 5. Remember, this is a LOGIC LEVEL port, not RS232. Don&#8217;t try to hook it directly to a PC serial port. You need either a level converter [...]]]></description>

Three of them are for Redboot itself, RedBoot, FIS directory, and RedBoot config.

I hooked the Hava Titanium to my laptop with an ethernet cable and ran the Hava Setup Wizard program. It found the unit, [...]]]></description>

		<description><![CDATA[When the Hava Titanium HD boots up the serial port operates at 115200 baud 8N1 while it&#8217;s in the RedBoot boot loader. When the Linux Kernel starts up it switches to 9600 baud 8N1 for all the boot messages. And just to make it interesting the script in /etc that starts the serial console switches [...]]]></description>

		<description><![CDATA[My guesses about the function and pin out of J21 were correct. I&#8217;ll post the pin out and instructions later. I now have serial access to the Hava&#8217;s boot loader. I can even interrupt the boot and stay in the boot loader. The Hava Titanium HD boots using the Redboot boot loader version 2.04e. More [...]]]></description>
