I'm trying to start emitting a signal from two Tx channels at once. HOWEVER, I was unable to obtain a working option, since the signal from both channels is emitted in portions in pulsation mode, that is, the signal is either not there.
Tell me how to properly launch two Tx channels on the device (using C++, iio-library and Linux)?

Just wondering if anyone has been able to get 20+ MSPS with their LibreSDRs and any of the precompiled firmwares. I've only been able to max out at ~11.5 MSPS, which is about 2x a regular Pluto. Testing was done using IIO in C running on a PC using iio_buffer_refill at various small and large buffer sizes.

About two months ago, I tried a firmware update which ended badly: the card no longer works and seem's bricked
=> unable to reboot with an sdcard.
=> No device appears on the USB port.
But there is a little sign of life when I plug in the debug port:
$ lsusb -v
....
Bus 001 Device 051: ID 0403:6011 Future Technology Devices International, Ltd FT4232H Quad HS USB-UART/FIFO IC

Is it possible to reinstall firmware with the debug usb port? how ? Found some stuff with openOCD, but this tool is not so simple...

another idea to unbrick the card ?

Hi, I realize that you aren't responsible for the LibreSDR but I kinda need help

I tried to copy your pre-built firmware on a freshly formated SD card fileformat FAT32

my LibreSDR does not seem to boot with them and keeps acting as a plutoSDR.
I draw this conclusion from not beeing able to detect it's ethernet port by pinging it, sniffing it or just seeing it in winbox. It still acts as a Pluto working fine from a USB port however I kinda need the ethernet capability.

I think I might be missing the step "Once it is running, the software can be updated using mounted drive" could you explain this to me in greater detail as I struggle to figure what I am supposed to do

Hello,

Could you please provide more details on how to write firmware to the internal flash drive? I've successfully run your firmware from the SD Card and now want to transfer it to the QSPI flash.

In your instructions, you mentioned:

Once it is running, the software can be updated using a mounted drive, just like with PlutoSDR. This will populate the QSPI flash, and LibreSDR will be able to run without an SD Card, with USB OTG acting as the normal PlutoSDR.

However, I am having trouble with DFU not working in my case. Could you please direct me to some documentation for LibreSDR?

Thanks!

Hi,
I'm sorry to ask here, but I found very few information on this Zynq 7020 / AD9361 SDR on the web.
Could you tell me if it works with srsRAN ? srsRan support plutoSDR but I would be reassured to have confirmation that still works with this hardware and software modification before putting €300 into it.
Thank you very much
