Compare the number of write cycles for your SDCard to that of the eMMC. If the number of write cycles is the same for both devices, the eMMC will fail first because of the smaller spare capacity given the use of wear leveling. To reduce the possibility of write failure, increase the size of your storage. http://en.wikipedia.org/wiki/Flash_memory http://en.wikipedia.org/wiki/Wear_leveling Regards, John > > > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google Groups > "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/d/optout. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
