	:~~Example~~: <code>~~sf probe~~</code>		: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.
			:<code>addr</code> = load address, defaults to environment variable loadaddr or if loadaddr is not set to configuration variable CONFIG_SYS_LOAD_ADDR
			:<code>baud</code> = baud rate for the ymodem transmission. After the transmission the baud rate is reset to the original value.

	:~~Description~~: ~~Initializes~~ the ~~OnBoard SPI Flash~~		: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.
			:How to start picocom on your PC: <code>picocom --baud 115200 /dev/ttyUSB0</code>
			:How to exit picocom on your PC: Entering the key sequence <CTRL-A><CTRL-X>
