Hello all,

I am using UHD 4.0 and when I look at the FPGA using Vivado over JTAG, I see that the FPGA is not programmed. So I send HG bitstream which is downloaded with "uhd_images_downloader" via JTAG to X310 (USRP-2945R). I am able to successfully ping the X310 and observe daughterboards and other information with "uhd_usrp_probe". With "uhd_fft" I can properly look at the spectrum of the signal.

However, when I want to flash the UHD 4.0 X310 HG image with "uhd_image_loader", I keep getting "Error: RuntimeError: Device reported an error during initialization.". When I read the contents of the EEPROM with “usrp_burn_mb_eeprom“, X310 appears to be in revision 7. I tried to write to the flash after updating to the revision 8, but I was unsuccessful again.

I can't use X310 without JTAG because of this interesting issue.  If you can point me towards solution, I would be grateful.

Thank you so much.

Hi

I am having the same problem using UHD 4.7 on a USRP-2974.  Note I have also used the JTAG recovery method to be sure, this works fine.

uhd_usrp_probe loads ok too. But when I use uhd_image_loader then there is a problem

uhd_image_loader --args="type=x300,addr=192.168.40.2" --fpga-path="x300_final.570080.bit"

[INFO] [UHD] linux; GNU C++ version 9.4.0; Boost_107100; UHD_4.7.0.HEAD-0-a5ed1872

failed.

Error: RuntimeError: Device reported an error during initialization.


Below is the output from reading the MB eeprom:

Done

Please ignore my last post, Unfortunately there is no way to delete it.

Basically I was remotely accessing the wrong USRP, the one with the above error has a hardware issue. This is why the loader is not working.
