There might be some really dumb questions in this so apologies in advance. 

 

Aside from problems with the default uEnv.txt I can build a booting system
using 2015.02. For which many thanks.  I've currently got 3 problems. Any
help here much appreciated.

 

1. How to point BR to use a newer kernel (TI 3.14.43 in this case)? Which
menuconfig setting(s) need to be changed and what would the resulting
.config look like?

 

If I simply replace the commit hash when I makeconfig with the branch number
I get the (painful!) result in the appended snippet below

 

2. If I configure the default kernel (3.12.10 ish) to build (specifically)
USB gadget modules, modprobe and friends do not work on the target. The .ko
modules are in the expected folder but somewhere a step is getting missed.
Any thoughts?

 

3. If I even need to do this by hand, how do I set up
/etc/network/interfaces to use etho? Does this need a custom script or can
it be added to some default file somewhere? Or, can I create an interfaces
file in $BUILDROOT /board/beaglebone?

 

4. Is there an officially sanctioned way to get a complete log of all build
steps? Redirection to stdout/stderr is a bit brittle. And I'd prefer to
avoid hacking remake or pymake

 

5. More generally, which .config files need to be backed up? I get
$BUILDROOT but how about for the kernel?

 

Thanks very much for any help here.

 

The extraordinarily maddening error follows. The problem here is that if I
rerun make the entire repo is cloned once more. Is this intentional? How can
it be stopped. My broadband is slow so a 3 hour clone is a complete pain..
