On my Ubuntu 18.04 host the system dtc was version 1.4.5 which also didn't support the -@ option, so I took Vijays advice and downloaded and built 1.6.0 which solved the problem. > That's correct.

I was sure I read that the other night but can't find the website or thread I was reading now so it was probably either bad information or my misinterpretation - apologies for that. > If I then run the following steps in the makefile manually, >> > bootstrap and bsp complete, but libbsd fails with the following >> error: >> > >> > [1497/2193] Compiling freebsd/sys/netpfil/pf/pf_lb.c >> > ../../freebsd/sys/arm/freescale/imx/imx6_ccm.c:54:10: fatal error: >> > arm/freescale/imx/imx_ccmvar.h: No such file or directory >> > #include <arm/freescale/imx/imx_ccmvar.h> >> > ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ >> > compilation terminated. >> > >> > This bug was recently fixed in the rtems-libbsd ( for both master and >> > 5-freebsd-12 branches), if you update to recent HEAD of the libbsd, then >> > this error will hopefully not be there. >> > Thanks for this. I thought my rtems-libbsd repo was up to date, but I did a git pull --recurse-submodules and now make libbsd succeeds. Loading the hello world test app onto the board produces the expected output in a terminal session, so I think I am now in a position to make a start on the eQEP driver. Many thanks for your help!
