SD Card Problem - can anyone explain the reason why ?

GreenYamo

As more people are getting the Pi's delivered, along with the problems of power supplies there also seems to be a problem with SD cards.

 

Now, I know that sometimes standards aren't quite as standard as they could be, but it seems very hit and miss what works and what doesn't. I have a number of SD cards for my cameras and they have all worked in the different devices, from an old 512 Meg card up to the gigabyte cards we have available today.

 

I have always tried to buy known makes (Sandisk mainly) and they have performed without fault in my camera equipment.

 

Can someone explain why these problems seem to affect the pi so much ? Surely you would design to the lowest common denominator and make sure that a good range of cards would work that are built to the SD standard, or am I missing something?

 

Thank you.

  • You need to either recompile your kernel,or apply the updates (firmware repo) from: raspberrypi · GitHub

     

    Easy method: download the firmware repo and copy the the contents of the boot directory to the boot partition of your SDcard.

     

    Compilation details on cross compiling a kernel (linux repo) can be found here: http://elinux.org/Rpi_kernel_compilation

     

    the running current .config file (needed to compile working kernel) can be found on a running raspberry pi in /proc/config.gz

     

    Worked for me... There is a known bug in the current SDHI driver which has been resolved in the nightly/weekly build in the repository mentioned above.
