New Pinebook Pro won't detect SD cards
#1
Shocked 
I recieved my Pinebook Pro this week and have been looking at getting a new OS on it today. I have a Sandisk SD card that I have formatted as FAT32 on my Mac. Upon insertion into the Pinebook Pro the SD card is not detected.

If I follow the `dmesg` logs there are no obvious messages when inserting the card which leads me to believe it is not being detected at all.

Is it possible I have recieved a unit with a faulty SD slot? What are the best ways to debug this issue?

Many thanks

One starting place would be to check the right USB port. Does any device in that right USB port work?

If nothing works in that right USB port, then perhaps it's a loose or poorly connected small board cable. The right ports are connected to the mainboard by a cable. So the flat cable could have a loose connection on either end.

Here is a picture of the small board, with the cable shown at the top of the picture.

Thanks for your reply. After some more tinkering I got the SD card to show after a re-boot which is good progress. I also managed to boot from it.

If I insert an SD card whilst the operating system is running, the SD card is not detected. If I re-boot with the card in, it is detected. Are the cards not hot swappable?

it sounds like the emmc os isnt loading the proper module. do you get any errors in dmesg or syslog?

that isnt normal.

They should be.  Is the card formatted with a file system the OS can recognize?
