2009-08-27 21:41:54 Basic SD Memory Card Question

David Kasper (UNITED STATES)

Message: 79326

I am trying to mount an SD memory card using the BF548 EZKIT and am using SVN 2009R1. During boot the SDH recognizes the card as the following message is displayed.

mmc0: new SD card at address e624

Next I checked the /dev folder but didn't find any devices that begin with /dev/mmc (see below). So I tried scanning for devices by typing the following which didn't seem to do anything.

echo 0 > /proc/driver/sdh

What do I need to do next to mount the device? Any help is appreciated.

David,

Could you post the full booting messages and your kernel config here?

Cliff,

See boot messages below. Where to find the kernel config? Let me know and I will also post that file.

It seems the SD card was not recognized correctly.The kernel config file is linux-2.6.x/.config.

BTW,have you refered to the doc about SDH in our wiki?

Cliff,

I got it working by formatting the card in my digital camera and then re-connecting to the BF548.

Thanks,

Dave
