3.1 DATA TRANSFER FAQ
A. Data tranfer using Serial cable(RS232C)
Step 1. Setup MITs i519
Before you use minicom you MUST choose PDA in UART check box, otherwise sending
and receiving of data between HostPC and i519 will not be functional.
Please follow the instruction as below.
Go "Setting (Tab) -> Sync Setup (Icon)" then setup UART to PDA.
Clicking [X],
If you followed the instruction then you can execute minicom right away. We
recommend you to give command as below since ‘-s’ variable will
show available configurations of minicom.
Then move to "Serial Port Setup" Press [Enter]
Change values as below. If you want to change a part, press [a] key. The focus
will move to edit-field.
If all setting variables are changed as picture shown, escape from here by
[Esc] key.
Move to "Save setup as dfl" and press [Enter]. Newer setup configuration
has been saved.
Now you finished minicom setting therefore you need to move down to "Exit"
to start minicom.
Execute minicom. You can execute this by following command.
Press [Enter]. You can see the console of i519 as picture shown.
Let's transfer data(davinci.txt) to i519.
We will download the file into /usr/home/Documents directory of i519, so move
to there and type following command.
Once you typed command, then quickly press "[Ctrl]+[a]" and "[s]".
Then select "Z-modem".
"rz" means that i519 will receive data by Z-modem.
A window will appear. It shows directory structure of your host PC. You can
move to directory by double-clicking [space-bar], and select files by single-clicking
[space-bar]. i.e., Multi-select is possible.
Select file that you want to transfer, then press [Enter]. The transfer progress
will be shown.
Check whether davinci.txt is successfully downloaded or not.
Step 2. Upload data to host PC
Let's send the file (SDC0000*.jpg) from i519(/usr/home/Documents/photo) to
your host PC. Move to the directory.
| # cd /usr/home/Documents/photo |
Before you upload file, decide target directory of host PC that you want to
put the file.
Without any command, press "[Ctrl]+[a]" and "[s]". Move
to the directory and escape the window by [esc] key.
Now upload the data ( SDC0000*.jpg files) by following command.
The transfer progress will be shown. Check whether SDC0000*.jpg is successfully
uploaded or not.
Step 3. Quit
To quit minicom, press "[Ctrl]+[a]" and "[q]".
B. Data transfer using USB cable
Step 1. Setup
Likewise serial cable, USB cable MUST be controlled by PDA. Therefore you need
to take following indications;
Go "Setting (Tab) -> Sync Setup (icon)" and then setup USB to
PDA.
Redhat Linux supports USB Ethernet by default.
When you connect the cable to PC, the Linux notices the interface and then loads
"CDCEther" module.
You can check or find whether the module is uploaded or not, by following command
in Linux HostPC.
i519 is ready to connect PC by default. E.g.: i519 has assigned IP 192.168.129.2
to "usbf"(USB Ethernet) by default.
Following command in PDA will show you active network configuration.
Now assign appropriate IP to USB Ethernet in Linux HostPC. Follow command will
connect HostPC to i519.
| # ifconfig eth1 192.168.129.1 up |
You can verify whether the cable is connected properly and network is active.
All procedures for connecting i519 to the Linux HostPC are finished. The command
as below checks current status.
(at host PC)
(at i519)
Step 2. Download data to i519 through "wget" application
"wget" is included at /bin/wget directory of i519.
If you install ftp application or web server on your HostPC, i519 can get data
from HostPC with higher transfer rate.
Or you can transfer to /var/www/html when using webserver(HTTP), or /var/ftp/pub
when using ftp(FTP) vice-versa.
Step 3. Using HTTP
Send command at host shell
| [root@mapae root]# mv davinci.txt /var/www/html |
Send command at the shell that executes minicom
# cd /tmp
# wget http://192.168.129.1/davinci.txt (When you use the file name without
change)
# wget http://192.168.129.1/davinci.txt -O leonardo.txt (When you want to
change the file name to leonardo.txt) |
Step 4. Using FTP
Send command at host shell
| [root@mapae root]# mv davinci.txt /var/ftp/pub |
Send command at the shell that executes minicom
# cd /tmp
# wget ftp://anonymous:tt@192.168.129.1/pub/davinci.txt |
Step 5. Sharing file system between HostPC and i519 via NFS
If you installed Redhat Linux 8.0 on your HostPC, then applications will be
installed by default.
However let’s double check whether following applications are exist.
nfs-utils-1.0.1-2.rpm
portmap-4.0-46.rpm |
If above applications are not installed yet, please install.
NFS server daemon refers the file of "/etc/exports" to know whether
client has permission to shared directory. Change the file according to your
favorites.
share-directory client1(options) client2(options)
/usr/home/Documents 192.168.129.2(rw,no_root_squash) |
[Note]
- rw : "read & write" permission are given
- no_root_squash : root account of client has the same authority of that of
server.
When you boot Redhat Linux 8.0, portmap application will be executed on default
but NFS is not.
Your PC can be NFS server after execute NFS. Start it by following command.
Instead of using NFS client, you can mount a directory of NFS server to i519.
This is easier than using NFS client, however you need to deactivate firewall
in HostPC.
Refer following example to deactivate firewall.
Select the second item "Firewall Configuration". Selection key is
[space-bar].
Then change the "Security level" to "No firewall".
Escape the window by pressing "OK" and "Quit".
Lets mount "/usr/home/Documents" directory of HostPC to "/mnt/PC"
directory of i519.
# mkdir /mnt/PC
# mount -t nfs 192.168.129.1:/usr/home/Documents /mnt/PC |
If any error message is not shown, NFS mount is done correctly.
Now i519 can get data from HostPC by regarding Linux command such as copy, move.
