- =============
- Synopsis
- --------
- ::
- loady [addr [baud]]
- Description
- -----------
- The loady command is used to transfer a file to the device via the serial line
- using the YMODEM protocol.
- The number of transferred bytes is saved in environment variable filesize.
- addr
- load address, defaults to environment variable loadaddr or if loadaddr is
- not set to configuration variable CONFIG_SYS_LOAD_ADDR
- baud
- baud rate for the ymodem transmission. After the transmission the baud
- rate is reset to the original value.
- Example
- -------
- In the example below the terminal emulation program picocom was used to
- transfer a file to the device.
- After entering the loady command the key sequence <CTRL-A><CTRL-S> is used to
- let picocom prompt for the file name. Picocom invokes the program sz for the
- file transfer.
