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