I solved my problem by using the argument bladerf=i with i = 0,1,2,3

Hi all,

I want to use 4 bladeRF devices on a single laptop. This means I have to load the FPGA file to all of 4 bladeRF devices. 

However, currently I can only load the PFGA file to 2 devices.

I am using the command: 

bladeRF-cli -l <path/to/FPGA/file>

Does anyone know how to load the FPGA file to 4 bladeRF devices on a single laptop? Please help me with this!

Thank you in advance.

 

Hi Van-Ly,

You might want to consider the Nuand forums [1], for bladeRF questions that don't directly pertain to GNU Radio.

As far as loading the FPGA, I would recommend you review the bladeRF wiki [2] with respect to having the

host software automatically load FPGA when opening a device handle. Personally, I prefer this method over

all others, and prefer to store bitstreams in ~/.config/Nuand/bladeRF/.

The gr-osmosdr wiki page [3] also provides a list of supported device arguments. One of these allows you

to specify an FPGA to load.

Best regards,

Jon
