iio_device_create_buffer(...) from rf_iio_imp.c

[uptools]

I have already installed the fpga bitstream to a pluto adalm v0.34, and compiled the srsenb, and set cpu scaling to performance. But when starting srsenb I get an error when trying to create the TX buffer:

$ srsenb

Any clues for this error in the iio_device_create_buffer(...) function?

Update to last message:
I also tested the bitstream on another program doing TX and RX in pluto-adalm, while the new bitstream was installed, I get the same iio_device_create_buffer(...) error, both for TX and for RX.
And same error also when trying to run txrx_test.
So I guess it is not a srsenb problem but a bitstream problem.

After disconnecting pluto from power (the usb cable) and then reconnecting, the iio_device_create_buffer error goes away.
