TODO:Automate, find out why separate touch commands are needed
Run this program twice:
1-st run ./used_files.py linux -1
and save shown timestamp
Then run (some mystery here)
touch src/drivers/ata/ahci_elphel.c
touch src/drivers/elphel/sensor_common.c
Wait 5 seconds and run (in a different console with appropriate sourcing)
bitbake linux-xlnx -c compile -f
Then again
./used_files.py linux <timestamp_from_the_first_run>
If somethong went wrong you will need to resore .cproject from eclipse_project_setup directory
For php:
bitbake php -c cleansstate
bitbake php -c unpack -f
bitbake php -c configure -f
./used_files.py php -1
bitbake php -c compile -f
./used_files.py php 1471044836.8
Doing:
bitbake php -c compile -f
./used_files.py php -1
bitbake php -c compile -f
./used_files.py php 1471044836.8
Corrupts make process
