USB ethernet adapter 0xdroid (Android) configuration on the BeagleBoard

Posted by Boris Stock in BeagleBoard, Research on 8. April 2010

If you’ve compiled the kernel with the correct drivers and enabled the general ethernet support correctly you should see the following entries when you type

netcfg

in the console:

lo    UP    127.0.0.1  255.0.0.0
usb0  UP    0.0.0.0    0.0.0.0
eth0  DOWN  0.0.0.0    0.0.0.0

The usb0 interface is the USB OTG ethernet gadget device (which is by default enabled in the kernel).
Now (do not forget to connect a network cable to your USB ethernet adapter and your router/switch) type the following commands in the console to configure the eth0 interface:

netcfg eth0 dhcp

This triggers the eth0 interface to get the IP etc. via DHCP (of course you need a router with DHCP enabled).
The eth0 interface now should have assigned a valid IP address if everything works like expected.

USB bluetooth and ethernet adapter support in 0xdroid (Android) on the BeagleBoard

Posted by Boris Stock in BeagleBoard, Research on 6. April 2010

If you’re using a build of 0xdroid on your BeagleBoard, you might come to a point where you want to use an USB bluetooth dongle or an USB ethernet adapter instead of the USB-OTG ethernet gadget solution. USB ethernet and bluetooth support is by default enabled in the 0xdroid kernel, but you might have to enable some drivers for your USB dongle to get everything working as expected.

To easily change the drivers which have to be integrated into the kernel or have to be loadable as a module follow the instructions on the 0xdroid kernel wiki page.

The key to an easy kernel configuration is

$ make menuconfig

which gives you a graphical interface to configure the kernel and selected the wanted drivers. Store the custom kernel configuration as .config.

Then build the kernel with the following commands:

$ make ARCH=arm .config
$ make ARCH=arm CROSS_COMPILE=../beagle-donut/prebuilt/linux-x86/toolchain/arm-android-eabi-4.4.1/bin/arm-android-eabi- uImage
$ make ARCH=arm CROSS_COMPILE=../beagle-donut/prebuilt/linux-x86/toolchain/arm-android-eabi-4.4.1/bin/arm-android-eabi- modules

If the build fails, deactivate the support for the faulty driver.

Then copy arch/arm/boot/uImage to 0xkernel-beagle.bin, copy the file on the SD card along with the android-beagle.ubi system image and the installer as uImage (copy the installer uImage as the first file on the SD card, then all the others). Insert the SD card into your board and boot it. The new kernel along with the 0xdroid Android build should be flashed to the NAND of the BeagleBoard. Beware: Your current installation will be wiped!

BeagleBoard accessories

Posted by Boris Stock in BeagleBoard, Research on 31. March 2010

I’ve also ordered the following accessories to get my BeagleBoard up and running (all ordered at Mükra Elektronik):

USB-Serial Adapter (you can get the drivers for MAC OS X and Windows here)

Serial Null-Modem Cable (9-pin d-sub to 9-pin d-sub)

USB 2.0 Mini-A Cable (for connecting the BeagleBoard USB OTG port to my MacBook as the power source)
