Compact Flash

There should be no 512M limits.

There is a limit of 2GB on FAT filesystem.

Please try read/write to the CF drive, and bypass the FAT.

dd if=/dev/hda of=/dev/null

dd if=/dev/zero of=/dev/hda

I typed the dd if=/dev/hda of=/dev/null

the output was:

hda:hda1

2001888+0 records in

2001888+0 records out

after I typed: dd if=/dev/zero of=/dev/hda

hda: hda1

/dev/hda: No space left on device

2001889+0 records in

2001888+0 records out

I tried using the CompactFlash in FAT and ext2, I got the same results, can not write more than 500MB to the disk.

Is it normal for the LEDs and the 7-segment displays to be counting? I did not write a routine to do that, and as soon as the system is up, it start counting.

Thanks for the input

it is possible to switch off the Leds and 7 Seg display when configuring the kernel.

After performing those commands, I had to reformat the disk. Now, I&#39;m able to write more than 512MB. It seems that I missed up the Disk, when I turned the card off before umounting the disk. Why is that? In my application, the power can go away while the board is running. Is there a way out of this??

There must be a task running in the background to blink the leds, and the seven segment displays. Is this standard with the uClinux-Nios port?

Thanks

You might try using a different filesystem. Since you&#39;re stating that power can go away, at any time, why not JFFS2 (or some other _journalling_ filesystem)?

In any case, I don&#39;t see your issue as specific to Nios/uCLinux (at this point), so you might try asking the question in other forums, or doing some internet sleuthing on your own.

[EDIT: Out of curiousity, I found this link (http://www.openpsion.org/howtos/series5mx_new/x176.htm). ]

Good luck!
