TMDXIDK437X: Quadrature encoder issue

Expert 1130 points

Part Number: TMDXIDK437X

Hi,

I am trying to add quadrature encoder support to the IDK motor control example.

after fiddling around I have narrowed my question to the following :

right after the board init , if I add the following lines , the SW crashes at the last line (a write to QEPCTL).

see attached screen shot.

any idea why ?
