Hi.
How to get linux terminal or console via miniusb gadgetpc. Is possible? What to do in the settings on linux gadgetpc and computer windows, linux.
Can communicate with speakers of Russian engineer via email?
-
yes, it is possible.
It is necessary to install the latest Mini-Max/ARM9 release
which is based on Linux 2.6.30.4
Please download and install http://www.bipom.com/files/mmarm9260e/mmarm9260e_setup.exe
Then copy all the files to USB Flash drive
It is necessary to install a driver on Win PC
http://www.bipom.com/support/gadgetpc/gserial.inf
GadgetPC will appear as a virtual COM port.
Then you can open any terminal program ( for example, hypertertminal) to establish connection with Linux console
>Can communicate with speakers of Russian engineer via email?
yes, you can send email to tech@bipom.com in Russian.

OK here is what I get when I tried this. To start the GadgetPC loads and I can see the console on the serial connection. It gets an IP but I can\'t see it on the net. After installing the new software I get a com port and the PC beeps when it installes the device but the Gadget PC does not boot to a point where I can communicate with it either on the network or over the usb port.
-
Please copy and paste the log you can see on the serial connection.
Maybe your problem is NTPD server. The board tries to connect to Internet to get time. Try to disable that server
in vars.sh

OK, Here it is:

The case has been set to lower because the website was complaining I was trying to post in all caps.
-
I can see the cause
> !!! ** Unable to read "gpcfs.gz" from usb 0:1 ** !!!
U-boot loader can\'t read the gpcfs.gz file from a USB Flash drive.
Please try to check if you can read the file connecting the USB Flash drive to a PC USB host port.
Also, try to check the USB Flash drive using standard Windows tools.
> USB: scanning bus for devices... 4 USB Device(s) found
3 external USB devices are connected to the board.
1 internal device is a USB hub.
If the board is powered from a USB host port of your PC
it can cause problems because it can provide only 500mA.
As the 1st step please disconnect 2 devices ( leave only USB Flash drive) to see.
-
OK, a bit confused here. Do I copt the gadgetPC files to the flash drive and then add the mmarm9260 files? The file gpcfs.gz is only in the gadgetpc devtools folder and NOT in the newer mmarm9260 devtools folder.
<edit> OK, I tried that and I can get to the OS [root@GadgetPC /] but the wireless does not activate and if I run ifconfig I get nothing but the prompt back.
I only had the flash drive and the wireless device hooked up before so I don\'t know where it found four devices unless it is just countin the ports available.
Thanks for all the help so far, I feel I\'m getting closer.
-
> Do I copt the gadgetPC files to the flash drive and then add the mmarm9260 files?
no, you don\'t need to copy mmarm9260 files at this stage.
Let\'s simplify everything because you have a serial console.
No needs to copy the mmarm9260 files to get a USB console.
Just format USB Flash drive to FAT32, then copy all files of GadgetPC release. Then, run LCP and edit vars.sh to match your configuration ( enable WiFi, assign IP, etc.)
Then , boot and show Linux log
Also, try to execute ifconfig command when it reaches [root@GadgetPC /]
-
ok, reformatted, reflashed with original files and i get the console. the wireless is passing packets as shown here:
please press enter to activate this console.

-
OK, I can see a wireless interface. It can send and receive packets. Very nice.
The next step is to configure your router
to create a correct wireless network. Please look at the picture ( below). Note, your wireless network has to use WEP
(http://www.bipom.com/support/gadgetpc/router.jpg)
-
(http://farm3.static.flickr.com/2553/4215926137_2464178079_o.jpg
) here is the image
-
Default SSID is DLinkRouter
I can see \'franklin\' on your picture.
Did you edit vars.sh ?
-
Yes, it\'s franklin on my network and in vars.sh. I\'ll double check the flash image to make sure but I changed it the first time and I hope I remembered to do it this last time.
-
Still no luck connecting to the Gadget over the network.
-
did you re-check SSID ?
-
Yes, franklin on both devices. Does the GadgetPC do DHCP?
-
yes, it can do DHCP.
But in case of WiFi connection the current Shell files do not try to use DHCP. So it can\'t be a problem.
Note, we provide a complete set of wireless executables
under /mnt/usb/wireless/sbin folder
So you can play with different SSID, keys, etc.
/mnt/usb/wireless/sbin/iwconfig rausb0 key KEY
/mnt/usb/wireless/sbin/iwpriv rausb0 set SSID= SSID
Also, you can use iwlist to look at the existing network
In my opinion, the hardware layer worked.
I mean WiFi adapters. Also, IPs are correct.
You have problems only with authorization to your Access Point (AP).
Also, did you try to connect to AP ( your router) from a PC with the same key, ssid, wep ?
-
I\'ll take a look at the other files you referenced but I did test it with another of my computers that connects to the AP wirelessly and your settings work just fine. (WEP and key)
-
Key looks OK and SSID set to franklin.
ESSID is "" is this correct?
It says it sees a wireless signal at -41db and displays it\'s mac address but still no communications in either direction.
What next?
-
>ESSID is ""
it has to be franklin on both GPC and router
-
OK I\'ve tried setting the SSID from
./iwpriv rausb0 set SSID= franklin
but this is what I get in return

the correct syntax is

I\'ll try that tonight, thanks.

-
I understand that. The ./iwconfig was to print out the data for you to see. If you look the key is set correctly as shown in the results returned from the ./iwconfig
encryption key:1237-4895-67 Thanks for working on this with me.
-
I tried ./iwconfig rausb0 Nickname "franklin" and it assigned a nickname but it won\'t stick on restart and it still will not ping either the router or other computers on the network.

According to your email I have started to install Debian on the flash drive. I\'m using Debian to do this and have gotten to page 8. I have the file debian_lenny_armel_small.qcow2 but can\'t extract it.
It appears the debian also does not have mkfs.msdos but I got around that by mounting the flash on a windows box and formatting it there.
What is it I need to do now?
I have a 247M FAT partition on /dev/sdb1 and a 3.3G EXT3 partition on /dev/sdb2.
Thanks for the help.
-
Note, the instruction describes all steps how to start from scratch. It is for advanced users who wants to generate
everything from ZERO point.
I guess you have to use the existing packages from bipomftp.
http://www.bipom.com/cgi-bin/yabb2/YaBB.pl?num=1263702424/1#1
1)
Download 2 packages ( Linux kernel and Debian RootFs)
to /home/mini/fs/debian folder
Linux kernel: linux2.6.30.4_06Feb2010.tar.bz2
RootFS (Debian Lenny): debian_rootfs_06Feb2010.tar.bz2
change to that folder
cd /home/mini/fs/debian
2) Insert the Flash USB drive to a PC
Let\'s say you have Linux partitions called EXT3
and MSDOS partition called FAT. I mean labels
It has to mount your 2 partitions to
/dev/sdb1 -> /media/FAT
/dev/sdb2 -> /media/EXT3
3)
sudo tar [ch8211]xvjf debian_rootfs_06Feb2010.tar.bz2
Password is max
It will create EXT3 folder under /home/mini/fs/debian
4)
Copy all files from EXT3 folder to your Linux partition
sudo cp -R EXT3/* /media/EXT3
5)
sudo tar [ch8211]xvjf linux2.6.30.4_06Feb2010.tar.bz2
It will create FAT folder under /home/mini/fs/debian
6)
Copy all files from FAT folder to your MSDOS partition
sudo cp -R FAT/* /media/FAT
Note, all the steps are described in details on the last page
of the installation guide.
7) Edit /media/EXT3/etc/network/interfaces file to match your needs
8) Unmount Flash drive, connect to Gadget PC.
Don\'t forget to adapt U-Boot
setenv bootargs mem=32M console=ttyS1,115200 root=/dev/sda2 rw rootwait
setenv bootcmd \'usb start; fatload usb 0:1 0x21000000 uimage; bootm 0x21000000\'
saveenv
-
Thanks, I\'ll try this tonight.
-
Now that I have the new software installed I can\'t get into the GadgetPC using ssh or the USB com port. On ssh it says I need to change the password and restart EVERY time I restart. On the gadgetpc com port it asks for a login but there does not seem to be a way to set one from the config tool. What am I missing and why does this need to be so hard?
-
There are 2 pairs of user name / password in accordance with the installation guide
user/user
root/root
