Forum: GNU Radio Can't upgrade E100 to UHD 003.005.000 release

I have built and installed uhd on my e100 but it appears the fpga image
version doesn't match the driver.  Is there something that might not 
have
been upgraded properly that I'm missing?

The module build is not compatible with the host code build.

I have opkg removed anything uhd or gnuradio related.  I have a history 
of
mucking about on this e100 and I don't recall what horrible things have
happened in its past.  My next step will be to start from a fresh 
angstrom
install but I'd prefer to avoid the time investment.

Matching md5sum of the installed e100 fpga image:

root@usrp-e1xx:~# md5sum
uhd-images_003.005.000-release/share/uhd/images/usrp_e100_fpga_v2.bin

It's not complaining about the FPGA versions, it's complaining that your
kernel module isn't up to date.

I think opkg update; opkg upgrade

SHould work.
