Can Android BSP build with multi-thread?

[DeanHuang]

Hi,

I would like to build i.MX6 Android BSP with multi-thread,

make PRODUCT-sabresd_6dq-eng- -j4 2>&1 | tee build_sabresd_6dq_android.log

but some files will not be built in out/target/product/sabresd_6dq/.

ex: system.img, recovery.img  (see out.png)

These files will be built if I do not use -jN

make PRODUCT-sabresd_6dq-eng- 2>&1 | tee build_sabresd_6dq_android.log

Does I use the wrong instruction?

In the case you don't specify the -JN, do you see the images? any error log on the compilation?

Hi Leo,

If I don't specify -jN, I can see the image under out/target/product/sabresd_6dq/.
