Hi,

I did all the steps on the readme file. But I could not initalize the Radio from the web interface. I hope I am missing something.

After power on web interface says that

But, when I click the radio init button, it turns to

state.

Radio init log files are 

FPGA revision: 0x102a
Configuring TSW3725 RF Board...
Configuring 10 Mhz external reference...
Checking 10Mhz External Reference...
ERROR: External reference check failed  0x7 (expected 0xf)

I examined the radio_init.sh and did the same configuration for ADF4001(via FPGA) from serial interface.

I realized that after this configuration lock state of ADF4001(fpga -r 0x0003) goes down.

if [ "$1" == "ext" ]

then

            echo "Configuring 10 Mhz external reference..."

            fpga -l

            fpga -w 0x0010 0x001f # ADF4001 Command data low

            fpga -w 0x000f 0xf896 # ADF4001 Command data high

            fpga -w 0x000e 0x6001 # ADF4001 & clock MUX

            fpga -w 0x0010 0x0010 # ADF4001 Command data low

            fpga -w 0x000f 0x0064 # ADF4001 Command data high

            fpga -w 0x000e 0x6000 # ADF4001 & clock MUX

            fpga -w 0x0010 0x0000 # ADF4001 Command data low

            fpga -w 0x000f 0x3001 # ADF4001 Command data high

            fpga -w 0x000e 0x6001 # ADF4001 & clock MUX

            fpga -w 0x000f 0xf892 # ADF4001 Command data high

            fpga -w 0x0010 0x001f # ADF4001 Command data low

            fpga -w 0x000e 0x6001 # ADF4001 & clock MUX

            fpga -u

            sleep 3

            echo "Checking 10Mhz External Reference..."

            fpga -l

            reference=`fpga -r 0x0003 | sed 's/.*value 0x/0x/'`

            fpga -u

            if [ "$reference" != "0xf" ]

            then

                        echo "ERROR: External reference check failed  $reference (expected 0xf)"

                        exit 1

Hi Engin,

You need to have an external 10MHz reference clock plugged into the CON1 connector of the SCBP.

This external clock must be 0.01 ppm to meet the precision requirements.

The voltage must be 3.3V.

Hi Laurent,

Thank you very much for your effort, this application is great for a quick start.

Best Regards,
