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.

Hello,

DO you have connect PIN69 with R7 (10k) ton of V3.3 (Vcc)

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!

I used the the WEB BOX hex bootloader found.

Is this the problem?

Miguel

[miguel]

wich LINUX hardware you use to fomat the card?

[Rubi]

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.

Cheers

When you use my Image think this Image is for a 14,3 Mhz Quarz.

[Rubi]

Ups

The image also has influence on the quartz.
Thanks for this comment, i used it with a 12 Mhz one.

Cheers

[MIGUEL]

Now the bootloader loader can show the LINUX.BIN not FOUND.

Please, let me know the procedure to FORMAT in 2 partitions in XP or copy the IMAGE...

Help me

Miguel

[Ulrich]

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)

Greetings
Ulrich

[Rubi]

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

[MIGUEL]

ok


But wich hardware do you use to estabilish communication with MMC/SD card. (MMC WRITE/READER HARDWARE)

Miguel

[MIGUEL]

Got success on MMC/SD format here!
Only the LINUX detected our MMC/SD programmer, believe!
Now, i will mout the RAM board !

My question

One question ULRICH, why sometimes and i have to insert and remove the MMC/SD many times to the BOOTLOADER detects the MMC card.
