Re: [Discuss-gnuradio] Yet another uhd_find_devices does not find usrp2 and no ping from 192.168.10.2

[Jim Simpson]

Hi Josh,

Here are the partitions:

-----------------

major minor  #blocks  name

   8        0  625131864 sda

   8        1  380204341 sda1

   8        2          1 sda2

   8        5  235879424 sda5

   8        6    9046016 sda6

-----------------

I have a 640GB drive dual booting windows and ubuntu.

Not sure what sda2 is. But this explains why it showed up on the gui.

The SD card was sdb and it showed up fine on the burner gui on the new card reader.

Thanks,

Jim

The card burner gui is already doing these verifications. I am surprised
that it finds sda2, its support to filter out the partition devices. Can
your send me whats in your /proc/partitions ( I assume this is linux).
This is the relevant code:
