loady command¶

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.
