Device Firmware Upgrade (DFU)
Overview:
The Device Firmware Upgrade (DFU) allows to download and upload firmware
to/from U-Boot connected over USB.
U-boot follows the Universal Serial Bus Device Class Specification for
Device Firmware Upgrade Version 1.1 the USB forum (DFU v1.1 in www.usb.org).
U-Boot implements this DFU capability (CONFIG_DFU) with the command dfu
(cmd/dfu.c / CONFIG_CMD_DFU) based on:
- the DFU stack (common/dfu.c and common/spl/spl_dfu.c), based on the
USB DFU download gadget (drivers/usb/gadget/f_dfu.c)
- The access to mediums is done in DFU backends (driver/dfu)
Today the supported DFU backends are:
- MMC (RAW or FAT / EXT2 / EXT3 / EXT4 file system)
- NAND
- RAM
- SF (serial flash)
- MTD (all MTD device: NAND, SPI-NOR, SPI-NAND,...)
- virtual
These DFU backends are also used by
- the dfutftp (see README.dfutftp)
- the thordown command (cmd/thordown.c and gadget/f_thor.c)
The "virtual" backend is a generic DFU backend to support a board specific
target (for example OTP), only based on the weak functions:
- dfu_write_medium_virt
- dfu_get_medium_size_virt
- dfu_read_medium_virt
Configuration Options:
CONFIG_DFU
CONFIG_DFU_OVER_USB
CONFIG_DFU_MMC
CONFIG_DFU_MTD
CONFIG_DFU_NAND
CONFIG_DFU_RAM
CONFIG_DFU_SF
CONFIG_DFU_SF_PART
CONFIG_DFU_VIRTUAL
CONFIG_CMD_DFU
Environment variables:
the dfu command use 3 environments variables:
"dfu_alt_info" : the DFU setting for the USB download gadget with a comma
separated string of information on each alternate:
dfu_alt_info="<alt1>;<alt2>;....;<altN>"
when only several device are used, the format is:
- <interface> <dev>'='alternate list (';' separated)
- each interface is separated by '&'
dfu_alt_info=\
"<interface1> <dev1>=<alt1>;....;<altN>&"\
"<interface2> <dev2>=<altN+1>;....;<altM>&"\
...\
"<interfaceI> <devI>=<altY+1>;....;<altZ>&"
"dfu_bufsiz" : size of the DFU buffer, when absent, use
CONFIG_SYS_DFU_DATA_BUF_SIZE (8MiB by default)
"dfu_hash_algo" : name of the hash algorithm to use
Commands:
dfu <USB_controller> [<interface> <dev>] list
list the alternate device defined in "dfu_alt_info"
dfu <USB_controller> [<interface> <dev>]
start the dfu stack on the USB instance with the selected medium
backend and use the "dfu_alt_info" variable to configure the
alternate setting and link each one with the medium
The dfu command continue until receive a ^C in console or
a DFU detach transaction from HOST.
The possible values of <interface> are :
(with <USB controller> = 0 in the dfu command example)
"mmc" (for eMMC and SD card)
cmd: dfu 0 mmc <dev>
each element in "dfu_alt_info" =
<name> raw <offset> <size> raw access to mmc device
<name> part <dev> <part_id> raw acces to partition
<name> fat <dev> <part_id> file in FAT partition
<name> ext4 <dev> <part_id> file in EXT4 partition
with <partid> is the GPT or DOS partition index
"nand" (raw slc nand device)
cmd: dfu 0 nand <dev>
each element in "dfu_alt_info" =
<name> raw <offset> <size> raw access to mmc device
<name> part <dev> <part_id> raw acces to partition
<name> partubi <dev> <part_id> raw acces to ubi partition
with <partid> is the MTD partition index
"ram"
cmd: dfu 0 ram <dev>
(<dev> is not used for RAM target)
each element in "dfu_alt_info" =
<name> ram <offset> <size> raw access to ram
"sf" (serial flash : NOR)
cmd: dfu 0 sf <dev>
each element in "dfu_alt_info" =
<name> ram <offset> <size> raw access to sf device
<name> part <dev> <part_id> raw acces to partition
<name> partubi <dev> <part_id> raw acces to ubi partition
with <partid> is the MTD partition index
"mtd" (all MTD device: NAND, SPI-NOR, SPI-NAND,...)
cmd: dfu 0 mtd <dev>
with <dev> the mtd identifier as defined in mtd command
(nand0, nor0, spi-nand0,...)
each element in "dfu_alt_info" =
<name> raw <offset> <size> raw access to mtd device
<name> part <dev> <part_id> raw acces to partition
<name> partubi <dev> <part_id> raw acces to ubi partition
with <partid> is the MTD partition index
"virt"
cmd: dfu 0 virt <dev>
each element in "dfu_alt_info" =
<name>
<interface> and <dev> are absent:
the dfu command to use multiple devices
cmd: dfu 0 list
cmd: dfu 0
"dfu_alt_info" variable provides the list of <interface> <dev> with
alternate list separated by '&' with the same format for each <alt>
mmc <dev>=<alt1>;....;<altN>
nand <dev>=<alt1>;....;<altN>
ram <dev>=<alt1>;....;<altN>
sf <dev>=<alt1>;....;<altN>
mtd <dev>=<alt1>;....;<altN>
virt <dev>=<alt1>;....;<altN>
Callbacks:
The weak callback functions can be implemented to manage specific behavior
- dfu_initiated_callback : called when the DFU transaction is started,
used to initiase the device
- dfu_flush_callback : called at the end of the DFU write after DFU
manifestation, used to manage the device when
DFU transaction is closed
Host tools:
When U-Boot runs the dfu stack, the DFU host tools can be used
to send/receive firmwares on each configurated alternate.
For example dfu-util is a host side implementation of the DFU 1.1
specifications(http://dfu-util.sourceforge.net/) which works with U-Boot.
Usage:
Example 1: firmware located in eMMC or SD card, with:
- alternate 1 (alt=1) for SPL partition (GPT partition 1)
- alternate 2 (alt=2) for U-Boot partition (GPT partition 2)
The U-Boot configuration is:
U-Boot> env set dfu_alt_info "spl part 0 1;u-boot part 0 2"
U-Boot> dfu 0 mmc 0 list
DFU alt settings list:
dev: eMMC alt: 0 name: spl layout: RAW_ADDR
dev: eMMC alt: 1 name: u-boot layout: RAW_ADDR
Boot> dfu 0 mmc 0
On the Host side:
list the available alternate setting:
