|
|
=============
|
|
|
|
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.

Configuration
|
|
-------------
|
|
|
|
The command is only available if CONFIG_CMD_LOADB=y.
|
|
|
|
Initial timeout in seconds while waiting for transfer is configured by
|
|
config option CMD_LOADXY_TIMEOUT or by env variable $loadxy_timeout.
|
|
Setting it to 0 means infinite timeout.
|
|
|
|
Transfer can be cancelled by pressing 3 times <CTRL+C> after two seconds
|
|
of inactivity on terminal.
|
|
|
|
Return value
|
|
------------
|
|
|
|
The return value $? is always 0 (true).
