Need Help with a TWR-K65F180M KSDK "NullPointerException" Error on the MCUXpresso IDE

[juanriveros]

I'm pretty new to using the MCUXpresso IDE, and the TWR-K65F180 microcontroller, so I'm not sure what to do here, but I keep getting this null pointer exception error when I use the TWR-K65F180 SDK I downloaded and I have no idea what to do at this point. Can anyone explain why this happens and what I can do to fix it? 

NullPointerException

Also, make sure that you actually select MCUXpresso IDE as your toolchain in the settings mcuxpresso.nxp.com when you generate your SDK.

This is the Build in the Archive

Hi Juan,

In addition, I have several customers meet similar problem as yours because of incorrect SDK package.

Please try this one instead. I use it without problem.

SDK_2.2_TWR-K65F180M.zip - Google Drive 

To avoid old association, please create a NEW workspace then drag SDK_2.2_TWR-K65F180M.zip to "Installed SDKs"

Have a great day,
Jennie Zhang

I ended up deleting all the SDKs I had previously downloaded, and the problem was fixed. I'm not sure what it was, because when I reinstalled the same SDK I had, the error message did not come up anymore. Thanks for your help though!

Juan,

Where did you get the SDK, and is it a recent download? What is the version of the MCUXpresso IDE you have installled? The MCUXpresso SDK builder is found here: MCUXpresso SDK Builder.

I've successfully imported it to the MCUXpresso IDE v10.0.2 [Build 411] [2017-07-11] release.

Thanks and regards,

MCUXpresso Support

The MCUXpresso is the most recent, I just downloaded it, uninstalled, and reinstalled it yesterday. As for the SDK, I got it from the MCUXpresso SDK builder. I tried making a new SDK from the builder, but the new SDK still shows the same Null Pointer Exception. Is there anything else I can do to fix the error?
