Subject: Looking for a driver for Compact Flash access
Date: Thu, 5 Apr 2007 17:08:32 +0200	[thread overview]
Message-ID: <1ea6be8e0704050808l20b80da7t3b8fad2ddc4f4948@mail.gmail.com> (raw)

Hi,
I'm have an embedded system using Compact Flash device.
I'm trying to figure out what is the right driver to access the CF.

The HW configuration is as following:
The CF is connected directly to MPC8541 CPU (PowerQUICC III,
Freescale), via local bus.
It is connected in Memory Mode, with 8-bit interface.

The questions I have:
1. What is the appropriate driver? Since memory mode is
PCMCIA-compatible PC Card ATA, I assume it is ide-cs. Is it right?

2. The card doesn't issue interrupts in this mode. I got the
impression the IDE driver relies on interrupts. Does it make it
unusable for accessing a CF in Memory Mode?


Most grateful for your help,
                                            Michael
