Hello
I try to configure the HSUSB1 module that communicates with a PHY device over ULPI bus. I enabled four clocks:
1. USBHOST_48M_FCLK with setting to high CM_FCLKEN_USBHOST[0]
2. USBHOST_120M_FCLK with setting to high CM_FCLKEN_USBHOST[1]
3. USBHOST_MICLK with setting to high CM_ICLKEN_USBHOST[0] and clear the bit PRCM.CM_AUTOIDLE_USBHOST[0]
4. USBHOST_SICLK with setting to high CM_ICLKEN3_CORE[2] and clear the bit CM_AUTOIDLE3_CORE[2]
The register UHH_HOSTCONFIG became accessible, but reading from TLL_CHANNEL_CONF_0 (0x4806 2040) still causes memory access exception. What am I missing in USB initialization? Could you advise which registers are involved in the USB ULPI initialization please?
Thank you
