Hi Lorenzo, Do you have the ability to remove the SD card and write it directly? If so, I would suggest doing this (rather than mender) and using the bmaptool method. This is way faster than mender. I do recall having issues updating with mender but I'm not 100% certain if the issues were exactly

2021-08-23 Thread Rob Kossler
Hi Dario, In the UHD manual, issue_stream_cmd() can be called from the UHD radio controller as well as several other controllers including an rx_streamer. The typical way to start streaming from UHD is to call this command on the rx_streamer controller, which in turn propagates this command to the

[USRP-users] Creating a graph for UHD4 with python

Hello. I want to create a graph with two fft blocks for UHD4 and manage them using python. I am using USRP E310. My FPGA connections look like this: 0/Radio#0:0==>0/FFT#0:0 0/FFT#0:0==>0/SEP#0:0 0/Radio#0:1==>0/FFT#1:0 0/FFT#1:0==>0/SEP#1:0 I want to receive data from two blocks at the same time.

Hi Rob, As I was mentioning we're trying to get rid of the streamers so ideally I'd only have two radios connected to my block which has no outputs. The graph would appear to be entirely in the FPGA and nothing except register reads and writes would enter or exit FPGA. As far as I understand there

Hi Dario, How do you start the streaming? Using issue_stream_cmd()? If so, is this called on the streamer object or on the DDC or radio? The reason I ask is that if you call it on the streamer, I'm wondering if your issue is related to command propagation. That is, the command is not propagating t
