FAT filesystem for compact flash

[Altera_Forum]

I am using a stratix evaluation board. 

I wanted to create a FAT filesystems on the compact flash onboard. Can i do this using the present uclinux port . If so what are the steps. Tell me the procedure as i am a beginner. Even a FAT systems without any OS wouls do.

I believe that archive is from Microtronix. It supports pretty much all the hardware on the board.  Assuming that that you built your NIOS with compact flash support:  In the NIOS II IDE you add support for the CF filesystem at compile time. It's an item in "Configure Kernal" - check the box for VFAT support. Then build the Kernal and upload it to flash ROM.  So after you log into uClinux, plug in the CF card. You should get a message similar to this: # hda: SanDisk SDCFB-8, CFA DISK drive ide0 at 0x80900800-0x80900807,0x80900838 on irq 8 hda: max request size: 128KiB hda: 15680 sectors (8 MB) w/1KiB Cache, CHS=245/2/32  hda: hda1  uClinux thinks the CF is a disk drive named hda1. Mount it as a VFAT filesystem. I put in under /var:  mkdir /var/cfdir mount -t VFAT /dev/hda1 /var/ -n  In theory you could put these commands in your /etc/rc file before you compile the file system to mount an installed CF card at boot.  After that you can cd /var/cfdir and read or write files.  Be sure to unmount the CF before removing it from the board. umount /dev/hda1  Somewhere in the documentation there is a caveat against booting with the CF installed and another against writing to the CF at all. It might be prudent to test with a blank CF card.

To Leslie, you said you had used the qp.zip which has a companion CFcomponent.zip: 

-Have you been able to compile successfully the CFcomponent zip file's project "cf_ide_test"? I tried it for 1S40fullfeatured using NIOSII V1.01 but got compile errors (see below); did you have to modify any code (eg# define CF_IDE_BASE , "cf",....) and which version of NIOSII you used? maybe V1.01 is too new?)  -besides this test, does ALtera have any other test to verify the inserted CFcard works or not? The "board_diag" project in the installation only test the onboard flash chip, not the CFcard Thanks # ####################################################  Error *** [obj/ideutils.o]
