After returning from WFI instruction, 5% of our custom boards doesn't work properly.
For example, after calling WFI instruction,
PWM doesn't output any signal(always LOW or HIGH) until 1msec timer interrupt happens.
Is there any procedure for using WFI instructnion?
Is it possible to use WFI instruction with iMX6 Solo processor?
