This didn't work for me. I got:
./librtemsbsp.a(bbb-i2c.c.1.o): in function `am335x_i2c_reset':
undefined reference to `__wrap_puts'
collect2: error: ld returned 1 exit status
This error is related to this change:
I guess I made this during the work to get rid of the bsp_specs. The
problem is that we have a cyclic reference: librtemstest depends on
librtemscpu which depends on librtemstest (via the wrapped output
functions). The librtemscpu and librtemsbsp are implicitly given at the
end via the -qrtems flag. I reverted the change since it seems to work
without it. Afterwards, I was able to install the BSP.

I got a different error:
[1163/1163] Linking build/arm-rtems6-beagleboneblack-minimal/zerocopy01.exe
testsuite/zerocopy01/test_main.c.96.o: in function `.LANCHOR0':
undefined reference to `_bsd_ip6_mroutemodule_sys_init'
I fixed this with this commit:
Which branch do you use for libbsd?
It seems the master branch. Here I get also your error:
[1084/1184] Linking build/arm-rtems6-beagleboneblack-minimal/condvar01.exe
./libbsd.a(uipc_mbuf.c.16.o): in function `m_unmappedtouio':
undefined reference to `PHYS_TO_VM_PAGE'
undefined reference to `uiomove_fromphys'
Could you please use the 5-freebsd-12 branch with the default build set.
This is what I use normally.
