Today I tried to use the QPCIe board but I have some questions.
I connected the QPCIe board with a USB3.0 cable, but there is no led and the fan is not spinning. I saw a SW3 on the board, do I need to switch it on?
Will USB3.0 power supply be enough for this board or do I have to use the 12v power supply?
If I plug it on my computer using the pcie socket, will the pcie socket provide enough power?
And I saw an additional port called ANT which I have never seen on LimeSDR-USB, what does it stands for?
If I plug my amplifiers on the QPCIe board (especially LNA), is the max power the same as LimeSDR-USB? I want to make sure that I won’t damage this board.
I saw at Section 2.2.9 “The last supply source option is the board edge PCIe connector.” Does that mean I can simply power it up by pluging the board into PCIe slot?
The J38 6-pin Power connector is optional or compulsory? Is it the same as the 6pin connector of PCIe graphic cards?
The chapter 3 is a quick start menu for LimeSDR-USB, could you update it for QPCIe?
I am trying to use QPCIe in LimeSuite these days. But I found some problems. In LimeSuite 18.04, I can receive signals at LMS1 channel A and LMS2 channel A, but nothing for channel B, and when I hit the enable MIMO checkbox it crashes.
Then I tried it with LimeSuite 18.06, it doesn’t crash when I checked enable MIMO, but the signal I saw in FFT viewer isn’t real. It seems that FFT viewer is showing signal at frequencies I am not intend to.
I downloaded the zip file today, there is a user guide inside. It’s written that I have to use USB 3.0 interface to upgrade the FPGA and power the board up through 12V external power supply?
And FX3 MCU has to be upgraded using cycontrol.exe? Can I upgrade it using LimeSuiteGUI like LimeSDR-USB?
Can I upgrade the FX3 MCU and altera FPGA through PCIe interface?
Can I use the board edge PCIe connector to power the board up while updating the firmware? I don’t have a reliable external 12V power supply and I don’t want to risk damaging the board. There is 3 options to power the board when using it normally, but for updating, will the other 2 powering methods be the same?
Is there a way that I can update its firmware and gateware without taking the board out from its pcie slot? Because it’s already in my server, it would take much effort to disassemble its brackets, etc. If the firmware/gateware updating has to go through USB3.0, can I connect the usb port to the computer while leaving the PCIe slot also connected with the board?
