Run rx/tx demo on bladerf board

Today, I updated the bladerf code,and according to the instructions as follows:
Code: Select all
# ./bladeRF/linux/apps/bin/bladeRF-cli -d /dev/bladerf0 -l hostedx40.rbf -s setup.txt -b
Loading fpga...
Done.
Set RX frequency: 1000000000Hz
Set TX frequency: 1000000000Hz [b][u]#Here set the center frequency of 1GHz[/u][/b]
Setting RX sample rate - req: 10000000Hz, actual: 10000000Hz
Setting TX sample rate - req: 10000000Hz, actual: 10000000Hz
Set RX bandwidth - req: 28000000Hz actual: 28000000Hz
Set TX bandwidth - req: 28000000Hz actual: 28000000Hz
Set TXVGA1 to -14
RX Frequency: 1228800000Hz [b][u]#But here print center frequency is 1.228GHz ,why?[/u][/b]
TX Frequency: 1228800000Hz
RX sample rate: 10000000
TX sample rate: 10000000
RX Bandwidth: 1500000Hz
TX Bandwidth: 1500000Hz
tx config file=samples.txt format=csv repeat=1 delay=0
tx start
How do I get this file?
samples.txt?
Another question:
I tried to set up a simple block diagram in gnuradio-companion using an osmocom sink block and sine source block, But there was a problem:"
RuntimeError: set_sample_rate failure due to device not being open Failed to read samples: File or device I/O failure". Any idea why this would be, or are there detailed instruction on how to set up the osmocom source block to work with bladeRF?
thanks.

If you change the 'tx to an 'rx', you will receive samples and they will be placed into a file called 'samples.txt'.
As for setting up the osmosdr blocks to work with your bladeRF, you can check
their website for more information.
Hopefully this helps.

I already tried but there still have an error：
Code: Select all
bladeRF> rx config file=/tmp/some_file format=csv
bladeRF> rx
State: Idle
File: /tmp/some_file
Format: C16, CSV
# Samples: 1024
bladeRF> rx start
Error: A fatal unknown error has occurred

I'm also getting the many of the "unknown error has occurred" in the CLI when poking memory locations in the LMS. I'm attempting to run the internal LMS calibration via a script of several pokes, and it's rare I can complete all of them without errors.

I've seen that recently. I am hoping our kernel engineer can get to the bottom of this and why it might be happening.
Do you know if you are connected via SS or HS?

I connected via SS, This error occurs.

This has happened to me as well running under ubuntu 12.04 on the latest vmware player. I was connected via both 2.0 (HS) and 3.0 (SS) in software. The port was always a 3.0 port. I can not say whether the problem is with vmware player or not since I don't have a 'real' linux machine yet.
FWIW, when I flash a compiled fx3 firmware, the version is always 1.0, regardless of what I set in the source code (e.g. v0.3)

What git repository revision are you on?

The latest -- but my linux kernel and many other system components were out of date. I may be able to report back on the virtual machine once I am done testing in this installed environment.
At this point, I have not tested with gnuradio yet, but the rx/tx demo on board (as per this topic) seems to be functioning although dmesg seems to be reporting my ports as high-speed. I'll investigate that further as well.

I have similar problems with bladeRF on Fedora19. I have the most recent software from git, firmware for microcontroller was compiled from source, FPGA config was downloaded from nuand.com. I don't have USB3 ports in my computer, so I'm using USB2.0 link. Firmwares upload successfully, board responds and returns correct config info:
Code: Select all
bladeRF> probe
Path: /dev/bladerf0
Serial: 0x0000000000000000
Firmware: v0.3
FPGA: v0.0
Unfortunately saving IQ samples to file doesn't seem to work. I'm using the following sequence of commands:
Code: Select all
set samplerate 2000000
set frequency 450000000
set bandwidth 1500000
rx config n=1000000 file=/tmp/iq.sav format=binl
rx
rx start
RX starts, seems to be working:
Code: Select all
bladeRF> rx
State: Running
File: /tmp/iq.sav
Format: C16, Binary (Little Endian)
# Samples: 1000000
However no samples are saved to the file and the process never stops (unless I send rx stop). An attempt to start rx again after stopping locks the cli app. I can kill the cli tool with ^C, start again and the rx process will start successfully, with identical results. The only sign of activity in the logs are these two lines form kernel module:
Code: Select all
Aug 01 02:51:51 localhost kernel: usb_control_msg(ptr=ffff880526f43eb8) len=4
Aug 01 02:51:51 localhost kernel: done usb_control_msg() = 4
Resetting the board, reflashing microcontroller, reprogramming the fpga, unloading and loading again the module do not help.
What is interesting, I managed to get the board to work once, the very first time I uploaded the firmware files (I checked with osmocom_fft). After reset it never worked again.

The changes made to the code 3 days ago fixed this issue.
