Tristate controller not mataching FLash chip control lines

Reset and Write Protect are not strictly part of the flash interface. Infact, they are not involved in data access, but they are rather asynchronous signals used for special device functions. Usually you drive them with a gpio, so they are not included in the flash controller.

Ok. I'll give that a shot. Makes sense I just wasn't sure what was going on there.

Hey so should I enable output enable on the Tristate controller? My flash part has an OE pin and I noticed that the tristate controller has a checkbox for that signal. It isn't checked, but I'm assuming I should check it and connect that pin to the OE on flash part? If so, that leaves me with only RST and WP left over which can just be set high on PIO like you mentioned.

So I finally got this working. I'm not sure why doing this triggered it but I think all I did after applying the above ideas was add the pin sharer (even though I'm not sharing any pins) and changed this

fd = alt_flash_open_dev(CFI_FLASH_CONTROLLER_NAME);

"/dev/CFI_Flash_Controller"

	//
	// Setup Flash
	//
	IOWR_ALTERA_AVALON_PIO_DATA(PIO_3_BASE,0xC0);
	fd = alt_flash_open_dev(CFI_FLASH_CONTROLLER_NAME);
	if(fd != NULL){
		printf("Flash recognized!\n");
		printf("0x%x \n", fd);
	}else{
		printf("Flash device not recognized!\n");
		printf("0x%x \n", fd);
	}

	//
	// Setup Flash
	//
	IOWR_ALTERA_AVALON_PIO_DATA(PIO_3_BASE,0xC0);
	fd = alt_flash_open_dev(CFI_FLASH_CONTROLLER_NAME);
	if(fd != NULL){
		printf("Flash recognized!\n");
		printf("0x%x \n", fd);
	}else{
		printf("Flash device not recognized!\n");
		printf("0x%x \n", fd);
	}
	// Test Flash memory
	ret_code = alt_write_flash(fd, 0, source, BUFF_SIZE);
	printf("Write return code: 0x%x \n", ret_code);
	ret_code = alt_read_flash(fd, 0, dest, BUFF_SIZE);
	printf("Read return code: 0x%x \n", ret_code);
	alt_flash_close_dev(fd);
	printf("Flash device closed! \n");
