@Jackdaw
I just tried that and xame a bit further but no completion. I now got
cannot find -lugpio
collect2: error: ld returned 1 exit status
makefile:9: recipe for target 'gpioRead' failed
make: *** [gpioRead] Error 1

I tried to copy all files in https://github.com/mhei/libugpio/tree/master/src to staging_dir/target-mipsel_24kc_musl/usr/include/ugpio but got "fatal error: ugpio-version.h: No such file or directory"
There is a file ugpio-version.h.in but no ugpio-version.h

Anyone managed to cross-compile the lmbench performance measurement tools (http://www.bitmover.com/lmbench/) and run on Omega2? I have problems with several header files.

@Jackdaw said in From "Cross-Compiling for the Omega" I cannot successfully build the gpioRead example:

I think you need libugpio headers https://github.com/mhei/libugpio. Copy those to staging_dir/target-mipsel_24kc_musl/usr/include/ and then compile.

What do you mean "copy"? fork the whole https://github.com/mhei/libugpio into "staging_dir/target-mipsel_24kc_musl/usr/include/" ?

@Lazar-Demin
I am another one very interested in low power consumption, including all sorts of sleep states, wakeup signals, wakeup times, etc, .Any information available?
