Largest MicroSD Size


#1

I was just curious what is the maximum MicroSD card size supported by the Dragonboard 410c running Linux. I read on one site that it was 64 GB, can anybody back that up officially? Any chance for 128 GB or larger?

well, it is a bit hard to find actually… we have tested up to 64GB on DB410c ourselves. The kernel output seem to indicate SDXC support

mmc1: new high speed SDXC card at address 0001
mmcblk1: mmc1:0001 62.5 GiB

So I am tempted to say that 128GB should work as well… we are still trying to chase down the information, but I am not sure we will get it…

Thanks for the information. I went ahead and purchased both 128 GB and 64 GB cards (64 GB as a backup) to test. It looks like the Sandisk Extreme 128 GB microSDXC UHS-I card is working just fine in my system. I tested writing to the full capacity with dd dumps and there were no surprises.
