OTP LED turned high

Hi,

Whenever I connect Tx-SDK board and XEM3001 board the OTP led is turned high. This happens when there is no power supply connection given to the TX-SDK-V2 board and the FPGA is programmed with TX_EN and sLA as high. Is it happens usually? When I checked the +3.3 V supply rail it reads 2.45 V

 Any information will be appreciated.

Regards,

Fathima
