The PIC18F24J50-I/ML on AD9739A-FMC-EBZ(rev C) seems not working well.
I have connected a USB cable to the AD9739A-FMC-EBZ but the AD9739A_SPI.exe (downloaded from High-Speed DAC Software Suite) couldn't recognize the device.
Actually, the LED XCR1 isn't lighted on, and my PC doesn't read any USB device when connecting AD9739A-FMC-EBZ.
My FPGA development board is Xilinx KC705, and I connect AD9739A-FMC-EBZ on the FMC LPC side
At first, I found the two jumpers JP1&JP2 missing, which has been discussed in:
I've put jumpers on JP1&JP2, and finally I got 1.8V on TP12 and 3.3V on TP1.
The power supply should be no problem now, but I still find the LED XCR1 not lighted on
The jumper on J2 has been switched to USB_SPI, and the VDD to PIC18F24J50-I/ML is 3.3V right now
Is there any USB drivers I should install on my PC in order to use AD9739A-FMC-EBZ?
Or, did I miss anything to start with AD9739A-FMC-EBZ?
Thanks for your help
Updates on my situation: Re-soldered C99 and C102 in "horizontal" direction. DAC clock is supplied from ADF4350 and now working fine with our own FPGA design. USB SPI and XCR1 still not working.
Hi, I found the C99 and C102 are in "vertical" in default, which it connects to the ADCLK914, not the ADF4350. However, on the ADI wiki site, it says these two caps are solded in "horizontal" in default.
Besides, what is your design environment? ISE or Vivado? Did you create a bit file by yourself or you used the one provided by ADI?
Thanks in advance
I'm working with my KC705 card with Vivado. The sample .bit file and .elf files from ADI are generated by ISE+EDK, but still loadable with Vivado hardware manager and xsdb (the command-line debugger comes with Vivado SDK). At first we have confirmed that we have no MU lock with ADI's bit+elf files (while the caps are vertical) then re-soldered the caps and we got MU lock. Now the board is running perfectly with our own HDL design and MicroBlaze SPI control code, but ADI stuff is sufficient to confirm the board is alive. We have no idea with USB-SPI PIC, but it's OK because we can control SPI wires by MicroBlaze.
