# kernel source code is in this repository:
#    https://github.com/96boards-hikey/linux/
# Kernel source code directory:

cd ${GEN_IMAGES_DIR}
# Note: here build result boot.img and dt.img are in folder ${PRODUCT_OUT}
#       To change this, change --output and -o.

remark it. if(print)==> if(0)

3. if mouse not work
==> remove type-C connection cable.
If OTG is connected, the log is shown
