yes. the problem is likely on the FPGA or perhaps the problem is
conceptual. The FPGA settings bus register is essentially "write
only". You need to implement additional logic on the FPGA to be able
to read this setting via a readback address. Take a look at the Ettus
FFT block implementation. I
Thank you very much for your help Rob.
If I have understand this is a FPGA problem ?
Because I have tried to do this with the DDC blocks and it is the same problem
when I use write for the register CONFIG at the address 130 I don't find find
the value that I had write in none of address.
Sorry
Hi Frederique,
I think that the first step is to forget about set_arg and get_arg for
now (until you get things behaving properly). The get/set arg are
used to access values in the UHD property tree and the configuration
of your xml means that when you use set_arg, it will automatically
call sr_wr
Hello Users,
I have creating a personnal block but when I read the value of my register it
return always the same value.
When I use set_arg and get_arg the value change like I want but when I try to
read the register that is associating with the precedent arg with sr_read32 it
look likes that t
Not sure if this resolves the issue, but have you tried running the custom
bootloader?
You can run /usr/lib/uhd/utils/b2xx_fx3_utils -Q to see if it's installed
correctly. b2xx_fx3_utils -B /path/to/images/usrp_b200_bl.img will install
it. You should run usrp_burn_mb_eeprom --read-all first to dump
