BladeRF 2 micro flash issues

Post by f4exb » Tue Sep 25, 2018 5:14 pm


this is what happens:

/opt/install/libbladeRF/bin/bladeRF-cli -L ~/Downloads/hostedxA4.rbf
Deferring device init until after FPGA load
Writing FPGA to flash for autoloading...

So far so good, but:

/opt/install/libbladeRF/bin/bladeRF-cli -i
[WARNING @ host/libraries/libbladeRF/src/board/bladerf2/bladerf2.c:1492] FPGA bitstream file not found.
[WARNING @ host/libraries/libbladeRF/src/board/bladerf2/bladerf2.c:1493] Skipping further initialization...
bladeRF> q

Then the BladeRF does not work.

I can still "soft load" with -l option but I would like to flash into non volatile memory to avoid loading each time I plug in the BladeRF.

Is there anything I can do?

Brgds, Edouard.

PS: this is v0.7.3 firmware since I am using the libbladeRF 2018.08 release (not the master HEAD)

"Soft loading" is much faster than SPI loading and with host-based autoloading enabled it's virtually seamless.

For SPI flash loading to work (at present), you have to unplug the board, plug it back in and wait several seconds for the lights to turn on before trying to open the device with bladeRF-cli. Otherwise, the FPGA load process will be interrupted. Rey has a PR that addresses this issue that should be pulled into master soon.

the autoloading is indeed working and fast so it is OK for me to do it this way.

Thanks and brgds, Edouard.
