Creating additional buzztime product variants

The buzztime device tree extends the rockchip tree. The actual starting point is in the rockchip/device/rk312x to avoid problems with lower level makefiles that may be expecting the 'official' device folder to be the rk312x folder.

The PRODUCT name can change but the model (BZT-T102) is on the FCC regulatory screen and should remain unchanged.

• identify the product code for the new device (eg bzt18uxa0N)

• create the device folder:
  run ./device/common/populate-new-device.sh buzztime bzt18uxa0N
  This creates a device/buzztime/product folder with default minimum contents.

• in device/rockchip/rk312x folder :
  copy bzt18uxa02.mk to bzt18uxa0N.mk
  change all references to bzt18uxa02 to bzt18uxa0N

  1. line 8: PRODUCT_NAME
  2. line 3: BoardConfig.mk folder location
  3. line 4: device.mk folder location

• in device/rockchip/rk312x/AndroidProducts.mk :
  add $(LOCAL_DIR)/bzt18uxa0N.mk \ to PRODUCT_MAKEFILES

• in device/rockchip/rk312x/vendorsetup.sh :
  create add_lunch_combo bzt18uxa0N-{variant} commands for user,userdebug,eng builds.

• device/buzztime/bzt18uxa0N/BoardConfig.mk
  This file manages lower level configurations (drivers, locales, etc). There shouldn't be a need to customize this file much. clone from device/buzztime/bzt18uxa02/BoardConfig.mk and change product references

  1. product BoardConfigVendor location
  2. sepolicy folder

• device/buzztime/bzt18uxa0N/device.mk
  This is the file where most customizations should reside. clone from device/buzztime/bzt18uxa02/device.mk

  1. change product references
  2. if a bootanimation.zip is used, it will override the buzztime glow bootanimation.

• copy the overlay, rockdev and sepolicy folders.

  • rename the product names in the rockdev folder filenames and contents

• create projects for the device and vendor product folders and checkin to dc-gitrepo-01

• update the repo_manifest to include the new device project folders.

Initial setup should be done.

At this point you would start copying the relevant portions of the bzt18uxa02 folder into the new product folder. Once bzt18uxa01 is created, it will be a better starting place. It should be ok to just copy the entire contents in and customize.
