[USRP-users] Raspberry Pi 4 sampling Rate

2020-11-03 Thread Alvaro Pendas Recondo via USRP-users
Hello, I am using a USRP B200mini with a sampling rate of 40MS that works perfectly fine connected to a laptop with USB 3. However, when I connect it to a Raspberry Pi 4 (which has two USB 3 ports) and I run the example benchmark_rate with the same sampling rate I get the output that I copy below.

I have only succeeded in running a B210 on a Raspberry Pi at lower data rates (closer to 12MS) so your experience is consistent with mine. On Tue, 3 Nov 2020 at 17:20, Marcus D. Leech via USRP-users < usrp-users@lists.ettus.com> wrote: > On 11/03/2020 10:49 AM, Alvaro Pendas Recondo via USRP-user
