Dear all,
I’m trying to load my own FPGA bitstream. The .rbf file, however, cannot
be loaded due to the errors as below. I’ve already copied the .rbf file
under the directories /usr/local/share/usrp/rev2 and rev4 as well.
Could you please guide me what the problem or the solution to solve the
problem? Thank you so much in advance for the help.
Can’t find fpga bitstream: ionosonde_tx_test0106.rbf
Traceback (most recent call last):
