Where is the code to enable the TPS65930 charger pump in BSP 6.14.01

Other Parts Discussed in Thread: TPS65930, OMAP3530

Hi,

I'm using the OMAP3530+TPS65930+ BSP 6.14.01.

TPS65930 can only supply 100mA when connecting with external devices. But my customer want 500mA. So I connected a DCDC supply to the VBUS which can be turned on through a GPIO.

According to some information on this forum, I should turn on this DCDC when the charger pump is turned on, and also turn off the charger pump to avoid charging the VBUS from two sources.

But the problem now is that I can't find where the OTG driver turn on the charger pump in the 6.14.01 BSP. It should be controlled by the OTG_CTRL.DRVVBUS but is not seems to be set/cleared anywhere in the code.

Do you know where is the code? appreciate if you could tell me...

 

Thanks

Luo Yang
