TPS25751: Dual Role Power device is unable to switch to become a source and charge the smartphone

Tool/software:

Dear E2E support team,

We're building a active speaker with USB-C. The speaker is powered by a 2-cell battery and we use the combination of TPS25751 and BQ25713 with patch bundle configuration as our charging solution. We expect that when the speaker is connected to a smartphone, It seemed like it could be a source, but it didn't actually charge the phone. The phone may pop up a charging notification after connecting to the speaker, but then immediately displays the end of charging. We did not measure any current output from the battery using a meter. Even if I issue a 'SWSr' 4CC command to the PD controller still get the same result.

I provide the USBCPD parameter configuration and the patch bundle data(*.c) we use for your reference. If anyone can provide any experience or solutions we would be very grateful.
