+
+## Source
+
+The CoreSDK can be downloaded as part of the "SimpleLink™ CC13x2_26x2 SDK". While the SimpleLink™ SDK is released under a proprietary license, the Core SDK is released untder BSD 3-Clause license.
+
+* Release notes of the SimpleLink™ CC13x2_26x2 SDK: https://software-dl.ti.com/simplelink/esd/simplelink_cc13x2_26x2_sdk/4.40.04.04/exports/docs/Documentation_Overview.html

+# Extracting from SimpleLink™ CC13x2_26x2 SDK
+
+The license manifest contains a list of all components of the SimpleLink™ CC13x2_26x2 SDK. Each files extracted from the SimpleLink™ CC13x2_26x2 SDK must be carefully compared with the license manifest to ensure that the file is part of the SimpleLink Core SDK and it is BSD licensed.
+
+The following files are required for Contiki-NG:
+
+* kernel/nortos
+    * License: the whole folder "kernel" is part of the Core SDK (BSD-3-Clause), except some files in kernel/freertos and kernel/tirtos. So kernel/nortos is all BSD-3-Clause
+    * The subfolders lib/ccs lib/gcc lib/iar and lib/ticlang are not used and can be deleted (saves ~50 MB)
+
+* source/ti/devices
+    * License: the folder is mostly part of Core SDK (BSD-3-Clause). source/ti/devices/cc13x2_cc26x2/ contains Radio Firmware (also BSD-3-Clause). source/ti/devices/radioconfig/.meta contains Radio Config (also BSD-3-Clause)
+    * The subfolder can be deleted
+
+* source/ti/drivers
+    * License: the folder is mostly part of Core SDK (BSD-3-Clause). Some files belong to other components but all of these are BSD-3-Clause
+    * The subfolders lib/ccs lib/gcc lib/iar and lib/ticlang are not used and can be deleted (saves ~50 MB)
+
+* source/ti/posix
+    * License: the folder is part of Core SDK (BSD-3-Clause)
