# HOW.GFIBER.quantenna.sdk.unpack

How to unpack and format a Quantenna QSR1000 CDK as a u-boot vendor_drop.
Source filenames look like: quantenna-sdk-v37.4.8.62.tar.gz

- initialize a repo with the default_unrestricted.xml manifest
- check out the vendor_drops branch
- remove the existing code
- unpack the downloaded SDK, it will create a new quantenna-sdk-... directory

  $ cd uboot/qsr1000
  $ git checkout -b l-vendor gfiber-internal/vendor_drops
    (use rm with -rf splat, but make sure you're in the right place)
  $ tar xvzpf $DOWNLOADS/$SDK

The SDK includes both u-boot and linux, but we're only interested in the u-boot part.
Prune the set of files/directories down to what we want

  $ cd quantenna-sdk-*
  $ rm -rf buildroot call_qcsapi_client_src.zip dbdc-quantenna-bin-*.tar drivers Kconfig libqcsapi_client_src.zip linux linux_2.6.35.12 pcie-host-quantenna-bin-*.tar pcie-quantenna-bin-*.tar post-process-configs.awk power_tables quantenna-bin-*.tar quantenna-hostapd-*.tar rfic6-quantenna-bin-*.tar common/doxygen

Move the remaining files into a quantenna specific directory under u-boot
  $ mkdir u-boot/quantenna
  $ for ix in board_config.mk common configs host include Makefile Make.toolchain; do mv ${ix} u-boot/quantenna; done

Then move everything up to where it really belongs
  $ mv quantenna-sdk-v37.4.8.62/u-boot/* quantenna-sdk-v37.4.8.62/u-boot/.??* .
  $ rm -rf quantenna-sdk-v37.4.8.62

  $ git add --all
