Hi all, I know there is a manual for this - http://files.ettus.com/manual/page_identification.html#id_naming Though I'm still having difficulties.
Firstly, can the eeprom of the device be read/changed from the device itself? I have ssh'd into the USRP, and get the following when attempting to read-all: root@ettus-e3xx-sg3:/usr/lib/uhd/utils# ./usrp_burn_mb_eeprom --read-all Creating USRP device from address: [INFO] [UHD] linux; GNU C++ version 7.3.0; Boost_106400; UHD_3.11.0.1-0-unknown [WARNING] [UDP] The recv buffer could not be resized sufficiently.

Please run: "/usr/lib/uhd/utils/uhd_images_downloader.py" Failing this, I attempted the same from my host machine (with the USRP device in usrp_e3x0_ network_mode). /usr/local/lib/uhd/utils$ ./usrp_burn_mb_eeprom --args="serial=3174549" --read-all This resulted in a very similar output with the error: Error: RuntimeError: Expected FPGA compatibility number 255.x, but got 16.0: *Note: *my host machine is running UHD 3.14.1 and I suspect this doesn't help the matter- I've attempted to roll this version back by downloading older uhd binaries - https://files.ettus.com/binaries/uhd/ though was getting all of these dependency issues. I'm new to Linux and this has been a head-f**k. I'm not sure how to troubleshoot this. Any advice would be great! Thanks, Joe
