TWR_SER2 board weird behavior

Hello,

 

i have TWR_SER2 board and the attached schematic for it.

 

I tested the ULPI_CLK output on transceiver itself by shunting the JP24 to get 3.3v from USB supply.

 

I checked the USB3300 reset signal and it is low (active high).

 

I check the ULPI_CLK output and it is 3 KHz instead of 60 MHz as said.

 

At this point, i am not sure what's happened yet, maybe i missed something, but i check the schematic many times.

if there is nothing can be spotted by NXP support, can i get a replace TWR_SER2 board?

 

Thanks,

Henry
