TWR-P1025 Illegal Instruction

[polarg]

Hi, I am using TWR-P1025 board to demo an application.

Before running the application, I upgrade the Linux SDK to V1.9. Then I cross-compile my application. But when I run the application in the board, it crash with 'unhandled signal 4 at 1060c01c lr 105edf34 code 30001 Illegal instruction'.

When I cross-compile the application, I did not use the script supplied with the tutorial to setup the environment. I used a cmake toolchain file to setup it. The content is as below and is there any problem in it?

Thanks
