Hi TI experts,

Please let me confirm the following questions.
[Question.1]
Is there any potential to have damage for AM572x, if some device which AM572x is connected supply the power before supplying the AM572x and input some voltage for I/Os on AM572x?

[Question.2]
Does AM572x have a hotswap function for some interface?

If you have any questions, please let me know.
Best regards.
Kaka

    Yes, this would damage the device.

    Are you talking about pluggable interfaces?  USB and SD come to mind right away.  There are others like HDMI and PCIe too.  I'm not sure I understand your question here.  I think you need to elaborate or potentially start a new, more specific thread.
