- 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"
- depends on MMC
- help
- This option enables using DFU to read and write to MMC based storage.
- config DFU_MTD

- This option enables using DFU to read and write to NAND based
- storage.

- 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 the support of "part" and "partubi" target in
- SPI flash DFU back end.

- 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.
