Get the NXP restricted extra packages (recommended):

$ merge_restricted_extras
(sometimes could be stocking on the waiting github response, please try again)

For a full clean build:

$ cook -j<N> (N is up to cors numbers on your host PC)

For an incremental build:

$ heat -j<N> (N is up to cors numbers on your host PC)

For clean the all build files:

$ throw

To configuration in Linux Kernel part:

$ cd vendor/nxp-opensource/kernel_imx/
$ recipe (or make menuconfig)

Flashing The Output Images

Output relative image files of path:

$ ls <source>/out/target/product/<your target platform>/

Quick way for flashing to board:

Enabling WiFi/BT function

Prepare WiFi/BT firmware

This BSP is supporting Qualcomm(QCA) WLAN module - QCA9377 as default configuration, Because of the license restriction, please contact TechNexion FAE or Sales to get licensed firmware files.

Contact Window: sales@technexion.com

After getting the firmware binary: .. Decompress the tarball and put all the firmware files into

<source folder>/device/fsl/<your target platform>/wifi-firmware/

Then take the QCA9377 folder as target path such as:

<source folder>/device/fsl/<your target platform>/wifi-firmware/QCA9377

Issue the command cook/heat again as previous Chapter "Compiling Environment Setup", WiFi/BT function will be working! Enjoy!

Frequently Asked Questions

1. jack-server compile error base on Ubuntu 20.04

Due to Google already stop update Android 8, it will cause compile error if users adapt newer openjdk revision such as Ubuntu 20.04 or above.

Users have two methods to fix this issue, one is refer docker way of chapter Compiling Environment Setup, that container is base on Ubuntu 16.04, another way is users need modify security configuration of openjdk using Ubuntu 20.04 host OS as follows:

Step 1: edit /etc/java-8-openjdk/security/java.security

Step 2. Disable TLSv1, TLSv1.1 protocols for Android 8 like this:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

Step 3. Restart jack-server

cd <source>/prebuilts/sdk/tools/
./jack-admin kill-server && ./jack-admin start-server

Step4. Recompile again, it should works.
