WL1837MOD: Will Mesh Time Sync Only Work with Timer 4?

Matt Barclay9

Part Number: WL1837MOD
Other Parts Discussed in Thread: WL1837, AM3354

We are designing an AM3354 + WL1837 product. Due to some voltage level requirements, we'd like to use Timer 5 instead of Timer 4 when we implement Mesh Time Synchronization. Can we use Timer 5?

Thanks,
Matt

Hi,

are you referring to the following time sync implementation?:

If this is the case then timer 4 in this case is the On AM335 side: GPIO 2_2 (TIMER4), and this pin is actually used as a GPIO.

If you want to use a different gpio line, you will need to change the souce line that uses gpio 66 (gpio2_2) to the different gpio you selected.

You also need to change your .dts file and mux the relvant gpio as input instead of gpio2_2.

Is this what you were looking for?

Best Regards,

Eyal

Hi,

Is there any other info needed on this or can we close this thread?

Thanks, I'm sure I'll have more questions when we implement time sync on the alternate GPIO line. Please close the thread.
