Instructions to use the serial port of your Armadeus board to communicate with your PC
Contents
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 sorry ! :-( After having booted your Armadeus system, launch lrz for receiving and lsz to send files:
Host --> Target
# cd /whereToPutTheFile/ # lrz -bZ
then in minicom Ctrl+A then 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
