Hi Nick, Derek's absolutely right, the FPGA interface was pretty stable for a long time! By the way, what are you planning to do with your USRP? What daughterboard do you have in there? There's one minimal caveat regarding using the latest possible UHD: somewhere after 3.8.0, the ability to use

Hi Nick, Marcus is correct, except for including the maximum UHD version you can use. The N200's FPGA compatibility number was increased in this commit on April 9, 2015. You need any version of UHD before that date. UHD 3.8.2 is the last release that did not include it. https://github.com/EttusRes

There's no workaround, but a single solution: You need to use the same UHD version as they do. So, uninstall GNU Radio and UHD, build UHD 3.6.2 (old) from source, build GNU Radio from source (which will then use that ld version of UHD). Then, things should work. Other than that: consider

Hi, I've borrowed some N2xx series Ettus devices and have been explicitly asked to not update the firmware/FPGA images on the devices. When I try to use the devices from GR 3.7.11.1 I get the FPGA incompatibility error and the commands to update the devices. *Please update the firmware and FPGA i
