The OP said he applied the 8V to the "USB mini" connector. I take that to mean P4, rather than the USB host port on P3. P4 does not have a USB power switch. It only connects to the ESD clamp U10, the PMIC USB input, and the SOC USB0_VBUS pins. The ESD clamp can safely handle the 8V input. The PMIC may be able to handle the 8V input, though it is greater than the recommended operating range max of 5.8V, since it is less that the absolute max of 20 V. However, the AM335x has a absolute max rating of only 5.25 V, so it is quite probably damaged.
