Stratix II development board : Compact Flash

Hello,

I'm working with the Stratix II (EP2S60) development board, and I'm testing my compact flash controller (IP). According to the schematic, the OE pin from the CON3 (Compact Flash connector) takes '0' for initial value (pull-down resistor). So, the compact flash goes into True IDE mode (compact flash specification). My question is: How can I swap to an another mode ? The only way is to initialize the OE pin to '1' before making a reset (compact flash specification). But according to the Stratix II reference manual, the Compact Flash reset pin is connected to the U3 device, and I can't control it.

Actually, my main issue is to reset the Compact Flash by myself, without resetting the whole system. Is there any way to do that ?

Best regards,

Julien

    No replies :(

    Anyway, I have an another question: Does all the CF card support CHS (Cylinder/Head/Sector) addressing mode ? Because I can't run a read or write operation successfully in that mode, while it is working perfectly in LBA addressing mode.

    Best regards,

    Julien.
