CF Issues

Hi,

We have had many woes with the compact flash interfaces. The best cards so far seem to be the Kingston 4GB cards. The following code will initialise them in IDE mode, even if they are already inserted:

//this is required to start the CF in IDE mode

void CF_Reset()

{

alt_u32 cf_status;

//reset

cf_status = ALTERA_AVALON_CF_CTL_STATUS_RESET_MSK;

IOWR(CFLASH_CTL_BASE, 0, cf_status);

Sleep(100); //let it reset

cf_status = CF_POWER_ON;

//power up

IOWR(CFLASH_CTL_BASE, 0, cf_status);

Sleep(100); //let it power up

//get status

cf_status = IORD(CFLASH_CTL_BASE, 0);

printfEx("CF Status: %ld\n", cf_status);

}

Regards,

Richard
