Hi,
This is something basic, but somehow I’m not succeeding when running my application on openAT target and I don’t understand why.
I’m using the M2M Studio and created a sample project based in the available sample “Hello World”. Then I built it with no errors and tryed the “Run As” “OpenAT Target Application”. I have the device connected successfully and can communicate with it normally (with AT commands).
The problem is when downloading the application to target. It always issues a “Error in file” error and then it resets. Please take a look at the attachement.
What am I doing wrong?
Regards.

Problem solved.
“Just” needed to upgrade to firmware version 6.57g and bootloader version 2.01F 🙂
