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

Introduction

When you only have a serial link (RS232) 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

when you build your root filessytem with buildroot, then modify your configuration:

[user@toto]$ make menuconfig

to add lrzsz package and then rebuild your rootfs

[user@toto]$ make

Check that lrz and lsz executable 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/

end then rebuild your rootfs

[user@toto]$ make

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 lrz for receiving and lsz to send files:

• Host --> Target

# cd /whereToPutTheFile/
# lrz -bZ

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

# lsz -b --zmodem filename
