config DFU_OVER_USB
bool
select HASH
depends on USB_GADGET
config DFU_OVER_TFTP
bool
depends on NET

config DFU_WRITE_ALT
bool
config DFU_TFTP
bool "DFU via TFTP"
select UPDATE_COMMON
select DFU_OVER_TFTP
help
This option allows performing update of DFU-managed medium with data
sent via TFTP boot.
Detailed description of this feature can be found at ./doc/README.dfutftp
config DFU_TIMEOUT
bool "Timeout waiting for DFU"
help
This option adds an optional timeout parameter for DFU which, if set,
will cause DFU to only wait for that many seconds before exiting.
config DFU_MMC
bool "MMC back end for DFU"
help
This option enables using DFU to read and write to MMC based storage.
config DFU_NAND
bool "NAND back end for DFU"
depends on CMD_MTDPARTS
depends on MTD_RAW_NAND
help
This option enables using DFU to read and write to NAND based
storage.
config DFU_NAND_TRIMFFS
bool "Skip empty pages when flashing UBI images to NAND"
depends on DFU_NAND
help
When flashing UBI images to NAND, enable the DROP_FFS flag to drop
trailing all-0xff pages.
config DFU_RAM
bool "RAM back end for DFU"
help
This option enables using DFU to read and write RAM on the target.
config DFU_SF
bool "SPI flash back end for DFU"
help
This option enables using DFU to read and write to SPI flash based
storage.
config DFU_SF_PART
bool "MTD partition support for SPI flash back end"
depends on DFU_SF && CMD_MTDPARTS
default y
help
This option enables the support of "part" and "partubi" target in
SPI flash DFU back end.
config DFU_MTD
bool "MTD back end for DFU"
depends on DM_MTD
depends on CMD_MTDPARTS
help
This option enables using DFU to read and write to on any MTD device.
config DFU_VIRT
bool "VIRTUAL flash back end for DFU"
help
This option enables using DFU to read and write to VIRTUAL device
used at board level to manage specific behavior
(OTP update for example).
config SET_DFU_ALT_INFO
bool "Dynamic set of DFU alternate information"
help
This option allows to call the function set_dfu_alt_info to
dynamically build dfu_alt_info in board.
config SYS_DFU_DATA_BUF_SIZE
hex "Size of buffer to be allocated for transfer to raw storage device"
default 0x800000
help
DFU transfer uses a buffer before writing data to the
raw storage device. This value can be used for setting the
size of this buffer. The size of the buffer is also configurable
through the "dfu_bufsiz" environment variable. If both are
given the size of the buffer is set to "dfu_bufsize".
config SYS_DFU_MAX_FILE_SIZE
hex "Size of the buffer to be allocated for transferring files"
default SYS_DFU_DATA_BUF_SIZE
help
When updating files rather than the raw storage device,
we use a static buffer to copy the file into and then write
the buffer once we've been given the whole file. Define
this to the maximum filesize (in bytes) for the buffer.
If undefined it defaults to the CONFIG_SYS_DFU_DATA_BUF_SIZE.
