Speeding up Bitbake build

[Samuel Chen]

Hi,

Does Multitech have some specific guidelines and tips on how to speed up the corecdp build ?

I have found general information pertaining to Bitbake:

Thanks,

Mainly the following:

* More CPU cores
* Fast disk I/O (SSD)
* Set BB_NUMBER_THREADS and PARALLEL_MAKE in local.conf based on the number of cores you have. If you keep these low and have more cores available, the build will be much slower than necessary
* Have source code pre-fetched (corecdp tarballs have sources downloaded already so little/no downloading is needed)

Also keep in mind that the initial build of corecdp will take a while, but subsequent builds in the same directory will be incremental and only build what is needed.
