Tue Apr 4 19:32:22 UTC 2017


Turing Computer is a designer and manufacturer of ARM-based
System on Modules, specialized on i.MX SoCs from Freescale/NXP.
This patch adds support for their Evaluation Board running i.MX6
Solo, Dual Lite, Dual and Quad  SoCs.

There are two board revisions according to the memory available:
Full-Sized Memory and Half-Sized (SMART) variants.

More information can be found at:

+How to use U-boot on Turing's i.MX6 Boards
+-----------------------------------------------------------
+
+- Build U-boot for Turing's i.MX6 Boards:
+
+$ make mrproper
+$ make mx6turing_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot.img.
+
+- Flash the SPL image into the SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Insert the SD card in the board, power it up and U-boot messages should come up.
+
+If you want to build for SMART variants (i.MX6Q 1GB and i.MX6DL 512MB), change it accordingly in the Kconfig file.
