[Q] Howto build Android for BayTrail Tablets topic

Hi,
I'm wonder about how to build Android-IA for BayTrail Tablets (Lenovo Thinkpad 8).
Regarding on the console output I think the Android-IA github repository is missing the baytrail_generic Android BSP.
Do you know where to get it? Or what's wrong with my commands?

I tried this:

Code:

---

repo init -u https://github.com/android-ia/platform_manifest.git -b release/android-4.4.2_r1-ia2
repo sync -j4
. build/envsetup.sh
lunch

---

Lunch creates this output:

Code:

You're building on Linux

Lunch menu... pick a combo:
    1. aosp_arm-eng
    2. aosp_arm64-eng
    3. aosp_mips-eng
    4. aosp_mips64-eng
    5. aosp_x86-eng
    6. aosp_x86_64-eng
    7. bigcore-eng
    8. core_mesa-eng
    9. core_mesa-userdebug
    10. core_mesa-user
    11. samsungxe700t-eng
    12. samsungxe700t-userdebug
    13. samsungxe700t-user
    14. mini_emulator_arm-userdebug
    15. mini_emulator_mips-userdebug
    16. mini_emulator_x86-userdebug
    17. baytrail_generic-eng
    18. baytrail_generic-userdebug
    19. baytrail_generic-user
    20. minnowboard_max-eng
    21. minnowboard_max-userdebug
    22. minnowboard_max-user

so with "lunch baytrail_generic-userdebug" I think it should be possible to build Kitkat, but instead I've got this output:

Code:

---

vendor/intel/baytrail_generic/baytrail_generic.mk:2: device/intel/baytrail/baytrail.mk: Datei oder Verzeichnis nicht gefunden
build/core/product_config.mk:231: *** vendor/intel/baytrail_generic/baytrail_generic.mk: PRODUCT_BRAND must be defined..  Schluss.

** Don't have a product spec for: 'baytrail_generic'
** Do you have the right repo manifest?

Thanks a lot!
