+Texas Instuments SK-TDA4VM Test and Development Board
+
+Description
+===========
+
+This configuration will build a complete image for the TI SK-TDA4VM
+board: https://www.ti.com/tool/SK-TDA4VM
+
+How to Build
+============
+
+Select the default configuration for the target:
+
+$ make ti_tda4vm_sk_defconfig
+
+Optional: modify the configuration:
+
+$ make menuconfig
+
+Build:
+
+$ make
+
+To copy the resultimg output image file to an SD card use dd:
+
+$ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+
+How to Run
+==========
+
+Insert the SD card into the SK-TDA4VM board, and power it up through the
+USB Type-C connector. The system should come up. You can use a
+micro-USB cable to connect to the connector labeled UART to
+communicate with the board.
