115KLE FPGA reporting size as 40???

[schrambo]

HI everyone.

This may be a bug, it may be a known issue, it may also just be a simple mislabeled variable values. I'm not sure. But when running the "version" command under bladeRF-cli, my 115KLE FPGA bladeRF reports the FPGA size as 40 KLE" not 115?, also the FPGA version is not reported.

Here is me loading the 115 firmware, querying version, then trying to load the 40 firmware just to test and confirm things.

Code: Select all

schrambo@daredevil ~/nuand $ bladeRF-cli -l bladeRF/fpga_firmware/hostedx115.rbf 
Loading fpga...
Done.

The card appears to be working fine as this is the first weird behavour I have noticed, here is an example of me setting soem values to the card etc. (DISCLAIMER: Linux expert / complete RF noob)

schrambo@daredevil ~/nuand $ bladeRF-cli

  Set RX frequency: 1575420000Hz

Is this something I should be concerned about?
I am yet to get anything working under gnuradio as I am a complete noob to the program and the world of RF development etc, however I plan to change that completely around soon.

There was a recent commit in the repository which caught a bug in reporting the size of the FPGA incorrectly.

Can you pull the latest repo and see if it still reports the same incorrect size?

Hello,

Thanks for the suggestion, Yes this did help. Just had to recompile the new pull, load the firmwares and its detected fine. Already I can notice some changes bladerf-cli
