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.
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.
Device Drivers ----> Graphics support ----> [*] Asynchronous Panels
----> [*] GiantPlus 240x320 Panel
Device Drivers ----> Graphics support ----> [ ] Synchronous Panel Framebuffer
----> Multimedia support ----> [ ] Video For Linux
-- Run command "make ARCH=arm" to build kernel.
4.3 How to do SMARTLCD driver test
-- After Smartlcd_giantplus_4_IMX51_Linux_2.6.31_09.12.01.patch applied, there will be an folder "IMX51_TEST" under linux.
-- Go to that folder, and run "make ARCH=arm", imx51_fb_test will be created.
-- Copy imx51_fb_test to rootfs/unit_test. and run.
