pwm on mimxrt1064_evk

[Chethan-TS]

hi,

i am trying a servo example with mimxrt1064_evk board where as per the official documentation on zephyr RTOS supports PWM on the mentioned board,

i have written a separate overlay for the same , i have uploaded all the files for verification

servo_motor_test.zip

but when i build the project i keep getting the following error,

west build -p -b mimxrt1064_evk

i don't understand the reason behind as far as i am aware i get the above error when i am building for unsupported board, which i am aware for the documentation for blinky example.

if i can get assistance for the same , it would be helpful.

PS: *version : main

thanks in advance,
Chethan T S

Hi Chethan,
The error I noticed in your code is due to not closing the parenthesis in "PWM_DT_SPEC_GET" in the main.c file (line 16).
