load fpga hostedx115.rbf succesful but " FPGA size UNKNOWN

[EcoKees]

I use bladeRF with Windows 10 and want to use MATLAB/SimuLink
installed BladeRF with libusb drivers
Everything seems OK but MATLAB complains and I think FPGA is not correctly loaded:

bladeRF> load fpga hostedx115.rbf

Loading fpga from hostedx115.rbf...
Done.

bladeRF> info

Serial #: b436de8c8212b9aeaaeba852246866e7

FPGA size: Unknown
FPGA loaded: yes
USB bus: 2
USB address: 10
USB speed: SuperSpeed

bladeRF>

Why FPGA size unknown? It should be something like KLE115 , but not Unknown?

thanks a lot jynik, I'll try that.

From my notes, I found:

bladeRF> version
[WARNING] FPGA currently does not have a version number.

Serial #: b436de8c8212b9aeaaeba852246866e7
VCTCXO DAC calibration: 0x9a5d
FPGA size: 115 KLE
Firmware version: 1.5
FPGA version: 0.0

I have no access to a spectrum analyser (the bladeRF is my spectrum analyser...).
The above might be used for a recalibration?

Hi jynik,
great idea. With the factory supplied value my bladeRF was slightly offset.
I was receiving at a frequency of 430.125 MHz and had best reception at a frequency of 430.125.600 (from memory).
Then I tried other DAC-values:
0x9000 430.1256
0x9b00 430.1253
0xa800 430.1249
0x9f00 430.1252
and finally
0xa500 430.125000

It was fun trying to calculate new values (guestimates) in hexadecimal
With the value 0xa500 the SDR console V2.3 receives at exact 430.125000 . I must presume that the frequency of the dutch repeater PI2NOS is at the right published frequency.

Ok, now further with the XB-200 board. I managed to desolder two resistors (I lost them, too small...). I am lucky to have an 8656b signal generator (HP) for testing!
Thank you jynik for your help, very encouraging to have people around to correct my mistakes....
