I have an Arduino ADK board, http://arduino.cc/en/Main/ArduinoBoardADK, the same one. I have burnt a program to the board and getting an error in the Serial Monitor as:

Error: OSCOKIRQ failed to assert

How to solve it?
Some people advised to supply 7-12V to Vin. I did that, but it didn't help.

for sure it is a power issue, the voltage regulater eats a lot of stuff try measuring the power at the +5v on the ADK and make sure the minimum standard voltage is there so that this ADK may work.

The problem is that USB devices take a lot to function and as such here not only the ADK needs power to function + the AVR but also the USB periferal device needs power for functioning too.

At +5v I am getting about 5.41v and at +3v it's around 3.14v.

ok so try again , what's the result?

[Reply #4 on:]

Tried, no change. Same error

Error: OSCOKIRQ failed to assert

And btw I have a rooted HP touchpad with CM9. Any idea if it has Android Open Accessory support? Running Android 4. I am not sure if it's usb port is compatible for ADK.

By default, CM9 doesn't have support for Android Open Accessory support. You have to specifically add the usb.jar file

Where can I get the usb.jar file, any download link?

And OSCOKIRQ failed to assert, error, is still not fixed. Anyone any suggestion?
I downloaded the required libraries like AndroidAccessory and USB_Host_Shield from https://dl-ssl.google.com/android/adk/adk_release_0512.zip. And then I modified it according to this http://marctan.com/blog/2012/04/06/fixing-the-adk-library-to-work-with-arduino-1-0/. Now the programs compiles without any error and can be burnt easily.
Can it be that the library has some problem and it's showing OSCOKIRQ error in the serial monitor?

You can get the files and the instructions from this forumn post http://forum.cyanogenmod.com/topic/26339-usb-accessory-mode-is-adk-supported-in-cm-7/

Someone seems to have fixed this issue. Try this solution http://stackoverflow.com/a/11239701/24949

Hey guys,
I am also stuck in the same issue..also tried solution suggested by sundar but it didn't work.
Is an external supply(other than USB) mandatory for Max3421 to work?

[Reply #10 on:]

Yes its needed , try plugging in a wall wart supply and it will work ,the concept is u..au it needs steady current.

Adding

Code:

delay(100);

before executing "acc.powerOn()" is working for me
