Could not load fpga

[BladeRunnerF]

I receive the following error when trying to do "bladeRF-cli -l hostedx40.rbf":

robert@robert-S400CA:~/Downloads$ bladeRF-cli -l hostedx40.rbf
Loading fpga...
Error: failed to load FPGA: Operation timed out
Could not load fpga


Which may also be related to another issue I'm having using GNURadio:

Not sure how to get this thing off the ground and running any help is very much appreciated.

Generally, when people have reported a timeout when loading the FPGA, I've found that the common issue has been that they were accidentally trying to load the wrong FPGA variant. For example, they were trying to load the hostedx115.rbf on a 40 kLE device, or vice versa.

If the Altera Cyclone IV FPGA on your bladeRF reads, EP4CE115..., and not EP4CE40..., you should be loading hostedx115.rbf.

Another way to check your FPGA size is to open the device in the CLI, and enter the "info" command, assuming you haven't clobbered the flash region that stores this info.

Code: Select all

$ bladeRF-cli -i
