Hello again, I'm still waiting to get my hands on my hummingboard but I started to look into device drivers by following the handbook. I have done the following on a source listing for CURRENT: 1) Created folder called echo_driver under /usr/src/sys/dev 2) Created new file called echo_driver.c with the code pasted from this handbook page: https://www.freebsd.org/doc/en/books/arch-handbook/driverbasics-char.html 3) created a make file with these contents: SRCS= echo_driver.c KMOD= echo_driver .include <bsd.kmod.mk> as per the Handbook https://www.freebsd.org/doc/en/books/arch-handbook/driverbasics-kld.html when I run make under /usr/src/sys/dev/echo_driver I get the following error: make: don't know how to make auto.obj.mk. Stop make: stopped in /usr/src/sys/dev/echo_driver I tried drilling through the makefile dependencies as best as I understood it and saw that /usr/src/share/mk contains the BSD make files (good to know!) and in the file auto.obj.mk is the first file in Makefile. Any help would be great. Thanks, Russhome | help
