**MMC/SD - Card not found! **

I verify all the connections but are ALL OK.

RE: Problem with MMC

Hello,

Do you have connect PIN69 with R7 (10k) to V3.3 (Vcc) or test a other mmc/sd card. My borad work with the mmc part very fine.
I have format the mmc/sd card with FDisk(Linux) format type16 with 2 Partitions (1=fat 2=ext2). But I thing the filesystem is not your problem.
When you have a problem with the Filesystem the error code is "Linux.bin not found"! I thing you have a hardware problem.

Greetings

Hello,

YES, I CONNECTED AND I HAVE 3,298V there!

or test A OTHER mmc/sd card.

OK, i will try too to find one!

My borad work with the mmc part very fine.

I got the MMC 128MB (SUPER TALENT) and works very well in my
digital photography machine

I have format the mmc/sd card with FDisk(Linux) format type16 with 2 partitions (1=fat 2=ext2).

I dont have UNIX, only XP, may i use my digital machine to format it?
have some idea how can i do to format...

But I thing the file system is emergency your problem.

I hope

When you have A problem with the file system the error code is "Linux.bin emergency found"! I thing you have A hardware problem.

Well, i verify and all is ok, because i see the MMC transmiting something..

What do you verify from the ID? The ID card or some ID that you got to FAT16 formatted?

Help me!

Greetings

Why dont you copy the image from the Web Arm page unsing dd ?
I also have only xp so I used a port of the dd program and copied ulrichs image. So I got the 2 partitions on my mmc without the need of Linux.

Hello,

If you have no Linux on you system, you can use Knoppix this is a Linux on CD. After that change to a shell and copy the Image with dd:

dd if=/image128mb.img of=/dev/xxx

If you need help type (man dd)

Ther is no need for Knoppix, you can also download the dd for windows.
f.e. from here:
