It is based on iMX51 2.6.31_09.12 BSP (SDK 1.7), tested on iMX53 3-Stack board.

1. Description

This is Smartlcd driver for Freescale MX51 SDK1.7 release. (Kernel: 2.6.31_09.12.00/01) 

2. File List

-- Smartlcd_giantplus_4_IMX51_Linux_2.6.31_09.12.01.patch: SmartLCD panel support patch, and unit test code.

-- Sample.config: the config file for reference.

-- readme.txt: this file, please refer to it before use the package.

-- SmartLCD Structure.pptx: the basic structure for smartlcd on IPUv3.

3. Requirement

- MX51_3DS Green board(TO2.0) - No hardware rework needed, only need plug the giantplus GMA722A0 to J10.
- MX51 SDK1.7 release package - L2.6.31_09.12.00_SDK_source.tar.gz
                               - redboot_200952.zip

4. How to use

4.1 How to use demo

-- Program default redboot.bin to board via ATKtools

-- Copy attached zImage to tftp folder (assume /tftpboot)

-- extract default rootfs to NFS folder (assume /nfsroot)

-- COPY attached imx51_fb_test to ~/unit_test folder.

-- Power on the board

-- After redboot is boot up, use following command to boot up linux kernel
   load -r -b 0x100000 zImage
   exec -c "noinitrd console=ttymxc0 root=/dev/nfsroot rootfstype=nfsroot nfsroot=10.192.225.221:/nfsroot/rootfs rw ip=dhcp"

-- Once the linux kernel launched, run following commands to test smartlcd panel.
   cd /unit_tests
   ./imx51_fb_test

4.2 How to use source code

-- Current release code is based on L2.6.31_09.12.00_SDK_source.tar.gz. Extract the file to your working folder.

-- Entering the working folder and type "./install", select a folder to install ltib. (such as .../ltib)

-- Entering ltib folder and type "./ltib" to build Linux platform.  If you are not familiar with this setp, please refer to doc "i.MX_3Stack_SDK_UserGuide.pdf" for detail.

-- Entering folder ".../ltib/rpm/BUILD/linux", copy "Smartlcd_giantplus_4_IMX51_Linux_2.6.31_09.12.01.patch" from release package to current folder
   Run command "patch -p1 < Smartlcd_giantplus_4_IMX51_Linux_2.6.31_09.12.01.patch"

-- When complete, run command "make ARCH=arm menuconfig", and you can refer to attached sample.config for detail.
