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
The board might not be programmed properly. Would you please return the board to us and we'll replace the board for you.
Sorry for any inconvenience this might has caused.
I am having the exact same issue. I am also using theAD9739A-FMC-EBZ and has the same missing jumpers and other issues. I am on a tight timeline, how can I get this resolved quickly?
Let me check some quick settings with you and then we can focus on the diagnostics of this board:1- The reason we didn't assemble JP1&JP2 from the first place is that we have noticed for some applications, those supplies can't be as clean as required. So we typically expect our customers to plug clean 1.8V and 3.3V supplies to TP12 and TP1, respectively. Make sure you either have shorted JP1 and JP2, or supplied power to TP1 and TP12.
2- Plan if you are using SPI over USP or FMC. In the case of using SPI over FMC, use a jumper and short pins 1 and 2 of P2. In the case of USB SPI, the jumper should short pins 2 and 3 of P2 and then as you plug in USB cable, XCR1 should light up.
3- Make sure you are using the latest version of our DPG Downloader and AD9739A update plugin
4- for the USB driver if USB SPI option is used, you need to install DPG Downloader and make sure the USB Driver option is selected
Please check all the above and see if SPI tool detects the AD9739A DAC.
I just got AD9739A-FMC-EBZ today, and having same problem with KC705 carrier board.- Soldered to short JP1 and JP2 on our AD9739A-FMC-EBZ- With P2 to "USB SPI", XCR1 doesn't light up even when USB connected
Additionally, wIth P2 to "FMC", we have no MU lock with the reference .bit + .elf files from the Analog Devices Wiki site. The S1 is on ADF4350 and CR1 nearby ADF4350 lights up.
Now I'm trying to get MU lock with my own FPGA design with MicroBlaze + SPI, but still no MU lock, too.Do we need "clearner" 1.8V/3.3V power supply?
Thanks in advance
After several months, I finally get a replaced AD9739A-FMC-EBZ from ADI.
However, nothing changes. The LEDs (XCR1&CR1) near PIC & ADF4350 are all blind.
I didn't load any bit file to my FPGA yet. I just short JP1&JP12 to power on in order to see if the board is fine.
Is it possible that my FPGA board is broken so the FMC aren't working? But I really get 1.8V on TP12 and 3.3V on TP1.
Can you please give me more details about how to make the LED light up?
Is there any configuration on FPGA before using this FMC board?
Thanks for your help.
