Today, I recompiled Kernel with some minor changes. I ran following commands on bitbake to add my changes to Kernel uImage:
bitbake -c cleansstate virtual/kernel
The fetch, unpack , configure and compile steps took nearly 5 minutes. However, do_populate_sysroot and do_package_write_rpm took more than 20 minutes!
Why the above two process took so long which wasn't the case on Open Embedded?
