linux on gadgetpc

[Igor_M]

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?

[vitaliy]

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.

[vitaliy]

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.

[franklin97355]

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.

[vitaliy]

>  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 /]

[franklin97355]

ok, reformatted, reflashed with original files and i get the console. the wireless is passing packets as shown here:

Code: [Select]

please press enter to activate this console.

[vitaliy]

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

[franklin97355]

here is the image

[vitaliy]

Default SSID is DLinkRouter
I can see \'franklin\' on your picture.
Did you edit vars.sh ?

[franklin97355]

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.

[franklin97355]

Still no luck connecting to the Gadget over the network.
