Instructions to use the serial port of your Armadeus board to transfer files from/to your PC.

Note Note: This page explains how to transfer files on the board when the Linux system has started, not from U-Boot !.

To know how to configure serial link for U-Boot communication, it's here.


Introduction

When you only have a serial link (RS232/USB) as connection with your devt PC (ie no Ethernet available), then you can use Zmodem protocol to send/receive files to/from your Shell/Console of your Armadeus board.

Installation

  • Target:

Modify your Buildroot configuration:

 $ make menuconfig

to add lrzsz package:
Menuconfig package.png

Menuconfig package net.png

    [*]   lrzsz

and then rebuild your rootfs:

 $ make

Reflash it or manually copy rz and sz executables found in $ARMADEUS_ROOTFS_DIR/usr/bin/.

  • Host:

Install lrzsz package, if not already installed on your system. For example on Ubuntu/Debian:

$ sudo apt-get install lrzsz

Usage

Template:Warning: You must use minicom as serial terminal and not kermit for the moment sorry ! :-( Be sure to have correctly configured Minicom (line speed, 8N1, no flow control, and correct download/upload directories path).
After having booted your board:

  • On your Target, open a new terminal on your serial link (here USB):
 # /sbin/getty -L ttygserial 115200 vt100
  • On your Host, launch Minicom and configure it to use /dev/ttyUSB1 at 115200, then connect it to this terminal
  • Use rz for receiving and sz to send files:

Host --> Target

 # cd /whereToPutTheFileOnTheTarget/
 # rz -bZ
 .. waiting to receive.

then in minicom do: Ctrl+A , s and choose zmodem protocol and the file to send.
Wait a little and your file will be copied to your board rootfs ! ;-)

Target --> Host

 # cd /whereIsTheFileToSendOnTheTarget/
 # sz -b --zmodem filename

Minicom handles the file receiving automatically (and put it in your $HOME by default)
