trouble with compactflash

Altera_Forum · ‎03-10-2005

I am currently trying to get the compact flash component to work with my 1C20 dev board from altera. I am using the linux_time_limited.sof core, and I have successfully compiled the kernel with vfat, IDE, and CF support. When I insert the card, the message pops up ID'ing the card (actually I usually have to insert the card twice to get the message). Can anyone help me trace down my problem. Below I have included the output of a console session that I hope illustrates the problem in better detail.

Hi jonv,

can you tell us your kernel configuration for ATA/ATAI/MFM/RLL support? You need enable the following:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support

Include IDE/ATA-2 DISK support

Use multi-mode by default

generic/default IDE chipset support

Other IDE chipset support

Altera CF (IDE mode) interface (Avalon bus) support[/b]

Thanks! I was hoping that it would be a problem in my kernel configuration. I only had EIDE support, and the Altera CF support checked. Is there some documentation that I missed that would have given me this information?

Thanks again Wentao, you da man!
