Instructions to use the serial port of your Armadeus board to communicate with your PC

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 Armadeus board.

Installation

  • Target:

Modify your Buildroot configuration:

[user@toto]$ make menuconfig

to add lrzsz package:
Menuconfig package.png

Menuconfig package net.png

and then rebuild your RootFS

[user@toto]$ make

Check that rz and sz executables are present in your RootFS and, if not, copy them to there:

[user@toto]$ cp ./build_arm_nofpu/lrzsz-0.12.20/src/lsz ./build_arm_nofpu/root/usr/bin/sz

end then rebuild your RootFS:

[user@toto]$ make
  • Host:

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

[root@toto]# apt-get install lrzsz

Usage

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 control, and correct download/upload directories path.
After having booted your Armadeus system, launch rz for receiving and sz to send files:

  • On your Target, open a new terminal:
# /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
  • 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 (put it in your $HOME by default)
