I've tried using hw_cpm_activate_pad_latches(), however it still doesn't work. The current code flow is as follows:


 hw_cpm_deactivate_pad_latches(); // allow pins to be changed
 hw_gpio_set_active(LED_PORT, LED_PIN); // turn on LED
 ...
 fflush(stdout); // empty buffer before latching pins and sleeping
 hw_cpm_activate_pad_latches(); // latch pins before sleeping
 // sleep here

Thanks!
