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 / SKIP / SCRIPT)
|
||||
- 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_TIMEOUT
|
||||
CONFIG_DFU_VIRTUAL
|
||||
CONFIG_CMD_DFU
|
||||
|
||||
Environment variables:
|
||||
the dfu command uses 3 environments variables:
|
||||
"dfu_alt_info" : the DFU setting for the USB download gadget with a semicolon
|
||||
separated string of information on each alternate:
|
||||
dfu_alt_info="<alt1>;<alt2>;....;<altN>"
|
||||
|
||||
when several devices 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 (8 MiB 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>] [<timeout>]
|
||||
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. If CONFIG_DFU_TIMEOUT option
|
||||
is enabled and <timeout> parameter is present in the command line,
|
||||
the DFU operation will be aborted automatically after <timeout>
|
||||
seconds of waiting remote to initiate DFU session.
|
||||
|
||||
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> [mmcpart <num>] raw access to mmc device
|
||||
<name> part <dev> <part_id> [mmcpart <num>] raw access to partition
|
||||
<name> fat <dev> <part_id> [mmcpart <num>] file in FAT partition
|
||||
<name> ext4 <dev> <part_id> [mmcpart <num>] file in EXT4 partition
|
||||
<name> skip 0 0 ignore flashed data
|
||||
<name> script 0 0 execute commands in shell
|
||||
|
||||
with <partid> being the GPT or DOS partition index,
|
||||
with <num> being the eMMC hardware partition number.
|
||||
|
||||
A value of environment variable dfu_alt_info for eMMC could be:
|
||||
|
||||
"u-boot raw 0x3e 0x800 mmcpart 1;bl2 raw 0x1e 0x1d mmcpart 1"
|
||||
|
||||
A value of environment variable dfu_alt_info for SD card could be:
|
||||
|
||||
"u-boot raw 0x80 0x800;uImage ext4 0 2"
|
||||
|
||||
If don't want to flash given image file to storage, use "skip" type
|
||||
entity.
|
||||
- It can be used to protect flashing wrong image for the specific board.
|
||||
- Especailly, this layout will be useful when thor protocol is used,
|
||||
which performs flashing in batch mode, where more than one file is
|
||||
processed.
|
||||
For example, if one makes a single tar file with support for the two
|
||||
boards with u-boot-<board1>.bin and u-boot-<board2>.bin files, one
|
||||
can use it to flash a proper u-boot image on both without a failure:
|
||||
|
||||
"u-boot-<board1>.bin raw 0x80 0x800; u-boot-<board2>.bin skip 0 0"
|
||||
|
||||
When flashing new system image requires do some more complex things
|
||||
than just writing data to the storage medium, one can use 'script'
|
||||
type. Data written to such entity will be executed as a command list
|
||||
in the u-boot's shell. This for example allows to re-create partition
|
||||
layout and even set new dfu_alt_info for the newly created paritions.
|
||||
Such script would look like:
|
||||
--->8---
|
||||
setenv dfu_alt_info ...
|
||||
setenv mbr_parts ...
|
||||
mbr write ...
|
||||
--->8---
|
||||
Please note that this means that user will be able to execute any
|
||||
arbitrary commands just like in the u-boot's shell.
|
||||
|
||||
"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> raw <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:
|
||||
|
||||
$> dfu-util -l
|
||||
dfu-util 0.9

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 / SKIP / SCRIPT)
|
||||
- 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

Environment variables
|
||||
---------------------
|
||||
|
||||
The dfu command uses 3 environments variables:
|
||||
|
||||
dfu_alt_info
|
||||
The DFU setting for the USB download gadget with a semicolon separated
|
||||
string of information on each alternate::
|
||||
|
||||
dfu_alt_info="<alt1>;<alt2>;....;<altN>"
|
||||
|
||||
When several devices 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, defaults to
|
||||
CONFIG_SYS_DFU_DATA_BUF_SIZE (8 MiB 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>] [<timeout>]
|
||||
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. If CONFIG_DFU_TIMEOUT option
|
||||
is enabled and <timeout> parameter is present in the command line,
|
||||
the DFU operation will be aborted automatically after <timeout>
|
||||
seconds of waiting remote to initiate DFU session.
|
||||
|
||||
The possible values of <interface> are (with <USB controller> = 0 in the dfu
|
||||
command example)
|
||||
|
||||
mmc
|
||||
for eMMC and SD card::
|
||||
|
||||
dfu 0 mmc <dev>
|
||||
|
||||
each element in *dfu_alt_info* being
|
||||
|
||||
* <name> raw <offset> <size> [mmcpart <num>] raw access to mmc device
|
||||
* <name> part <dev> <part_id> [mmcpart <num>] raw access to partition
|
||||
* <name> fat <dev> <part_id> [mmcpart <num>] file in FAT partition
|
||||
* <name> ext4 <dev> <part_id> [mmcpart <num>] file in EXT4 partition
|
||||
* <name> skip 0 0 ignore flashed data
|
||||
* <name> script 0 0 execute commands in shell
|
||||
|
||||
with
|
||||
|
||||
partid
|
||||
being the GPT or DOS partition index,
|
||||
num
|
||||
being the eMMC hardware partition number.
|
||||
|
||||
A value of environment variable *dfu_alt_info* for eMMC could be::
|
||||
|
||||
u-boot raw 0x3e 0x800 mmcpart 1;bl2 raw 0x1e 0x1d mmcpart 1
|
||||
|
||||
A value of environment variable *dfu_alt_info* for SD card could be::
|
||||
|
||||
u-boot raw 0x80 0x800;uImage ext4 0 2
|
||||
|
||||
If don't want to flash given image file to storage, use "skip" type
|
||||
entity.
|
||||
|
||||
- It can be used to protect flashing wrong image for the specific board.
|
||||
- Especailly, this layout will be useful when thor protocol is used,
|
||||
which performs flashing in batch mode, where more than one file is
|
||||
processed.
|
||||
|
||||
For example, if one makes a single tar file with support for the two
|
||||
boards with u-boot-<board1>.bin and u-boot-<board2>.bin files, one
|
||||
can use it to flash a proper u-boot image on both without a failure::
|
||||
|
||||
u-boot-<board1>.bin raw 0x80 0x800; u-boot-<board2>.bin skip 0 0
|
||||
|
||||
When flashing new system image requires do some more complex things
|
||||
than just writing data to the storage medium, one can use 'script'
|
||||
type. Data written to such entity will be executed as a command list
|
||||
in the u-boot's shell. This for example allows to re-create partition
|
||||
layout and even set new *dfu_alt_info* for the newly created paritions.
|
||||
Such script would look like::
|
||||
|
||||
setenv dfu_alt_info ...
|
||||
setenv mbr_parts ...
|
||||
mbr write ...
|
||||
|
||||
Please note that this means that user will be able to execute any
|
||||
arbitrary commands just like in the u-boot's shell.
|
||||

|
||||

|
||||

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::
|
||||
|
||||
$> dfu-util -l
|
||||
dfu-util 0.9
