Re: [Discuss-gnuradio] No revision detected MB EEPROM must be reprogrammed!

Hi Matija,

thank you for your information.

Just to get it right, did you run the command

usrp_burn_mb_eeprom --values="revision=6" 

with your corrupted USRP and after that the error still persists?

Cheers,

Julian

However note: it doesn't work with the oroginal usrp I've been working with. The eeprom error persists!

Hi Julian,

Thank you so much for your reply!

As it just so happens, I have an update for you: we have multiple x300's here. I've reinstalled again GNURadio & UHD (again 3.9) and with another x300, it works perfectly! I'm not really sure what to make of that, but it might help you guys to narrow it down.

Thanks again and keep up the great work!

Matija

Hi Matija,

I'm sorry but we are still not 100% sure how this might have happened but the team is working on figuring it out. 

In the meantime you might want to rewrite the value in the EEPROM.

In order to do that you need to do the following:

1.) comment the hw_rev check in x300_impl.cpp (located in uhd/host/lib/usrp/x300) (Lines 625-632)

2.) rebuild uhd

3.) run usrp_burn_mb_eeprom --values="revision=6"

After that you should be able to switch back to stock UHD without issues. 

Again, Sorry for your inconvenience. I hope that gets you going.

Cheers,

Julian

Dear all,

I've been working with GNURadio & UHD/USRP for quite some time now. All of a sudden I started seeing the following messages when running my flowgraph, on which I couldn't find any info:

UHD Warning:
    No revision detected MB EEPROM must be reprogrammed!

At the time I was using UHD 3.9. Anyhow, a colleague told me that he also used to have problems with too new versions of UHD, but that those disappeared as he started to use UHD 003.008.005. So I erased all traces of GNURadio & UHD and reinstalled from scratch using the build-gnuradio script, now specifying that I want UHD version 003.008.005 installed. Furthermore, I ran the usrp_x3xx_fpga_burner tool to rewrite the EEPROM of the X300. Now, when I  wish to run my GNURadio flowgraph, I get the following return messages:

linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.008.005-0-g7efbd15b

>>> Done (return code 1)

Did anyone else experience the same problems? Can I not use UHD 003.008.005 with the X300? I'm assuming that something weird happened during the installation as the board revision number is so odd..
I'm using an USRP X300 with a UBX-160 daughterboard, connected over 10Gb ethernet. Gnuradio version: 3.7.7.2. My system is 64bit Ubuntu 14.04.

Any help is greatly appreciated!

Kind regards,

Mat
