The internal eMMC is nothing more than a permanant SD card. The problem is if it goes bad you can't replace it. Once the BBB boots it basically runs in RAM. It does reads when necessary from the SD card but rarely does writes. Using the removable SD card makes it very easy to have complete backups that can be inserted in seconds. This would not be possible with the internal eMMC. If you were out somewhere in a remote location you would have to take a complete BBB written with the backup instead of just an SD card to accomplish the restore. <br><br>So with that in mind I made the decision to not use the internal eMMC. For the "C" version of the BBB you have a perfectly good copy of Debian prei-nstalled in the eMMC that we don't touch so if you should ever decide to use your BBB in a different way you can just remove the SD card and it will boot Debian.<br><br>The disadvantage is you need to pay an extra $10 for an SD card but I find that a small price to pay for the flexibility. <br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div>> Date: Tue, 22 Jul 2014 23:11:32 -1000<br>> From: jim.pilgram@gmail.com<br>> To: arm-allstar@hamvoip.org; arm-allstar@hamvoip.org<br>> Subject: Re: [arm-allstar] node building<br>> <br>> Dave, Doug,<br>> Thanks for the reply.

The mmc flash on the<br>> BBB is not modified at all, by default. So, you can take an existing,<br>> working uSD card out of the BBB where it was setup and plug it into a new<br>> BBB and the new BBB will be functionally identical to the old (and the old<br>> BBB will then again boot the original firmware it came with from the<br>> manufacturer).<br>> <br>> 73, David KB4FXC<br>> <br>> <br>> <br>> On Tue, 22 Jul 2014, James R.
