<p class="MsoNormal">hello,<o:p></o:p></p>
<div>
<p class="MsoNormal">i flashed a firmware update to a minnowboard turbot today going from 0.78 to 0.92 and after the flash the linux install on a SD card would not boot. i did not spend a bunch of time researching if this is to be expected so if it is i apologize
for the post. but, would this be a normal thing? i was thinking maybe some kind of file allocation table structure might have change between the firmwares. thanks<o:p></o:p></p>
