USB Power Issue

Hello,

We have Zynq 7000 SOC based development board. In USB Host Programming, is it possible to select the inter chip power. We tried this, but when we update the value in PORTSCR[PTS] and IC_USB[3:0] register, then it is not updated. Please tell me and provide some HAL layer library in baremetal for USB host.

 

Thanks  Regards
