NAME

       colorhug-flash - A firmware updater for the ColorHug colorimeter

SYNOPSIS

       colorhug-flash [ --verbose ] [ --filename ]

DESCRIPTION

       This manual page documents briefly the colorhug-flash command.

       colorhug-flash allows you to update the firmware on your Hughski ColorHug colorimeter.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.

		 --help
	      Show summary of options.

		 --verbose
	      Show extra debugging information.

		 --filename
	      Flash a specific firmware file.

	      Usually colorhug-flash contacts the internet and downloads update metadata to work out the firmware file to use.	This  flag  allows
	      the user to use a custom image.

ENVIRONMENT

       Setting	COLORHUG_EMULATE will allow you to run this tool without any real hardware attached, although the program will fail when the flash
       write is verified.

NAME

     flash -- subsystem for flash-like memory devices

SYNOPSIS

     #include <dev/flash/flash.h>

     device_t
     flash_attach_mi(const struct flash_interface *fl, device_t dev);

DESCRIPTION

     Flash-like devices can register themselves to the flash layer with the flash_hw_if structure.  This structure has function pointers and other
     fields.

     The attachment can be done by calling flash_attach_mi() with this structure and the device's device_t as an argument.  Return value is the
     flash layer device.  The flash_interface structure is shown below.

     struct flash_interface {
	     int (*erase) (device_t, struct flash_erase_instruction *);
	     int (*read) (device_t, off_t, size_t, size_t *, uint8_t *);
	     int (*write) (device_t, off_t, size_t, size_t *, const uint8_t *);
	     int (*block_markbad)(device_t, uint64_t);
	     int (*block_isbad)(device_t, uint64_t);
	     int (*sync) (device_t);

	     int (*submit)(device_t, struct buf *);

	     /* storage for partition info */
	     struct flash_partition partition;

	     /* total size of mtd */
	     flash_addr_t size;
	     uint32_t page_size;
	     uint32_t erasesize;
	     uint32_t writesize;
	     uint32_t minor;
	     uint8_t type;
     };
