I’m building a custom board using jetson tx2 4gb .
In my board, i removed M.2 interface, PCIe,SD Card, Sata, and Serial port (except uart0_x, for serial console)
GPIO Extender, DSI, CSI, JTAG, Debug.
and add a RS485, USB hub ic (USB5537b), usb to eth (RTL8152) x2.
When i power up my custom board, there was a massive heat on USB hub ic and there was a strange beep sound from TX2 module.
USB and the other peripherals are work fine but i think there is a critical power problem.
I thought the problem was caused by things I added, so I got rid of them all.
But the issue has yet to be resolved.
Too many noise (ripple) on every sources.
I checked schematics, and PCB patterns , all of them but i couldn’t find where the problem begin.
Did I miss anything?
