Hi Support Team,

Please find our configuration

1) Only we have problem with USB ports.

a) At USB2.0 connectors when we do mass storage transfer, we are facing the issue it is failing to write on the storage device.

b) At Bluetooth device (through Mini PCIe connector), when we do data transfer, sometimes it is crashing.

c) At LTE controller, Once the signal lost,  not establishing the network connection again

2) The Other PCIe devices connected to the PCIe switch PI7C9X2G404SL

1) WIFI module (through Mini PCIe) is working fine.

2) PCIe to ethernet controller is working fine.

Regards

Hi Arulpandiyan

in general one can check nonworking peripherals connecting

them to i.MX6 PCIe port directly, without PI7C9X2G404SL switch.

If this will work, then seems problem in switch customization,

probably one can ask support from switch vendor.

Best regards

igor
