Hi,
I've got problem with my Arduino Yun. I have configured my Yun, and so far everything works OK, except for the SD card. It can not be accessed. When I insert it, it does not appear in the system. I've tried accessing it over SSH, by browser and also simply looking at mount points list ("ls /dev" and also "df"). It does not seem to get recognized. I've tried using two different uSDHC cards (one 8GB and one 16GB) and have also tried formatting them under different Operating Systems (Ubuntu, Windows 8.1) to different file systems (NTFS/FAT32). I've also tried making arduino folder inside. There's no problem whatsoever with USB drives. Therefore at this point, I'm pretty sure it is HW issue.
So my question is: Is there any way to check if it's a HW problem ? Or is there some stupid mistake I made ?
