6 4. Compiler Environment 4.1 Vmwa re7.0+ubuntu10.04 Install Vmware7.0 in windows OS, and then install ubuntu10.04 in vmware to compile. You can see the installing steps in the initial version. 4.2 Install the Cross Compile toolchain cross compile toolchain version: arm -2009q3 location: Tools\linux You had better install the cross compile toolchain to /usr/local/arm/ ( The makefile have designated the directory in the source ). User also can install other versions of the tool chain according your demand.you can reference to the following installing steps: # mkdir /usr/local/arm # tar xvjf arm-2009q3.tar.bz2 C /usr/local/arm # gedit /etc/bash.bashrc Add the following information in the end of bash.bahshrc : PATH=/usr/local/arm/arm-2009q3/bin:$PATH Export PATH Save bash.bashrc and execute the following command to set a default cross-compiler: #source /etc/ bash.bashrc Execute the following command to check if the cross-compiler has been installed successfully and check the revised version: # arm-linux-gcc -v 5. Compile the Source 5.1 Compile u boot u-boot.bin is mainly used to guide and start the kernel.the steps of compiling: # tar xvf uboot_smdkv210-boardcon_v6_inand.tar.gz # cd uboot_smdkv210-boardcon # make distclean # make smdkv210single_config # make If it is ok, you can get the u-boot. bin in the current path. 5.2 Compile kernel There is em210.config file which we had configured in the kernel source folder,and you can use directly, the default LCD is 7 inch. The steps of compiling: # tar xvf kernel_v6.0_inand.tar.gz # cd kernel # make distclean EM210 Linux User Manual 6

7 # cp EM210_iNand_config.config # make If it is ok,you can get the zimage file in the arch/arm/boot folder. 5.3 Generate the root file system(ext2) 1 generate the genext2fs command # sudo tar xvf genext2fs tar.gz # cd genext2fs #./configure # make # make install Now the genext2fs will be generated in current directory,as follow: 2 Edit script(the script is in \Linux\Tools\linux directory) #!/bin/bash num_blocks=`du sk /home/zgf/desktop/210/system tail -n1 awk '{print $1;}'` if [ $num_blocks -lt ]; then extra_blocks=3072; else extra_blocks=20480; fi num_blocks=`expr $num_blocks + $extra_blocks` num_inodes=`find /home/zgf/desktop/210/system wc -l` num_inodes=`expr $num_inodes + 500` /home/zgf/desktop/genext2fs -d /home/zgf/desktop/210/system -b $num_blocks -N $num_inodes -m 0 /nfsboot/system.img tune2fs -L system /nfsboot/system.img tune2fs -C 1 /nfsboot/system.img tune2fs -O rw /nfsboot/system.img e2fsck -fy /nfsboot/system.img EM210 Linux User Manual 7

8 Note: the red part needs to be changed to your own the corresponding file system, the file system name should be change to system.blue command is your first step to do the command position. Give permission to execute, execute the following command: # sudo chmod +x install.sh 3 unzip the file system source code package and generate the file system of ext2 format # sudo tar xvf system.tar.gz # sudo./install.sh Now system.img is in directory nfsboot,you can burn it to the development board and then start the system. 6. Burn images to inand 6.1 Burn uboot.bin to inand when there have no uboot.bin in inand. Step 1: Set EM210 board to USB boot mode. The boot mode configuration: Boot Mode J1 J2 J3 J4 J5 J6 inand ON ON OFF OFF ON ON USB OFF ON ON ON OFF ON Step 2: EM210 board connect 5V adapter, serial cable, USB cable (between EM210 USB OTG port and PC). Step 3: Power on EM210 board. The PC will report that found new hardware if your PC have not ever install this usb drive(tools\windows\usb_download_driver),install the driver as followings, EM210 Linux User Manual 8

9 Click next and select tools/windows/usb_download_driver director. EM210 Linux User Manual 9

10 EM210 Linux User Manual 10

11 Click Browse and select tools/windows/usb_download_driver/secusb2.sys. Click Open and then clilck OK. EM210 Linux User Manual 11

12 Now,the USB download driver is installed successfully. EM210 Linux User Manual 12

13 Step 4: Open DNW(Tools\windows\dnw\dnw.exe) Serial Port->connect: to connect EM210 serial console configuration->options: to set USB Port download address:0xd This time on the top of DNW window will show: [COM1:115200bps][USB:OK] [ADDR:0xd ] Then lunch USB Port->transmit:transmit to download images\v210_usb.bl2.bin to EM210 RAM. notice: All the images and tool cmd.exe(include V210_USB.BL2.bin,u-boot.bin,zImage-7inch_R and system.img) are stored in the directory \Linux\Images Confiure->Option to set USB Port download address: 0x23e00000 lunch USB Port->transmit->transmit to download Linux\Images\uboot.bin to EM210 RAM. This time uboot.bin are going to run in EM210 board and will output message through serial port. Following pictures show the detailed process: EM210 Linux User Manual 13

17 Step 5: Select option e go into command line mode, EM210 Linux User Manual 17

18 in uboot console create 3 partitions for inand as followings, SMDKV210#fdisk -c 0 Then lunch fastboot SMDKV210#fastboot The pc will report that have found new hardware if you have not ever install this usb driver(tools\windows\usb_fastboot_driver) EM210 Linux User Manual 18

19 Now you need to install the USB fastboot driver. Click next and select Tools/windows/usb_fastboot_driver director. EM210 Linux User Manual 19

20 Click Browse and select Tools/windows/usb_fastboot_driver/i386/WinUSBCoInstaller.dll. EM210 Linux User Manual 20

22 Now,the USB fastboot driver is installed successfully. EM210 Linux User Manual 22

23 Step 6: Open cmd.exe(\linux\image, double-click directly and open cmd.exe in the directory) and lunch fastboot flash bootloader u-boot.bin to flash uboot.bin to inand, following pictures show the detailed process. EM210 Linux User Manual 23

24 6.2 burn kernel and system Step 1: Set the JP106 to inand boot mode as follow: Step 2: Boot Mode J1 J2 J3 J4 J5 J6 inand ON ON OFF OFF ON ON Power on EM210 board and press any key within 3 seconds in serial console, Select option e go into command line mode,(if your PC have not ever install fastboot usb driver,the PC will report found new hardware),and input fastboot in uboot console create 3 partitions for inand as following, EM210 Linux User Manual 24

25 Open cmd.exe(\linux\image, double-click directly and open cmd.exe in the directory),and lunch follow command to burn kernel and system to inand: fastboot flash kernel zimage fastboot flash system system.img EM210 Linux User Manual 25

26 So far, all images have been flashed to inand. And now we can reboot the system. Step 3: uboot setup boot parameters, select [s]: EM210 Linux User Manual 26

27 Power on EM210 board and press any key within 3 seconds in serial console, Select option e go into command line mode SMDKV210#rm etc/pointercal SMDKV210#reboot Now the system go into calibrate the touch screen mode. Note: if you want to erase the system partition,please power on EM210 board and press any key within 3 seconds in serial console, select option f and y, it will be cleaned. As follow: EM210 Linux User Manual 27

28 Note: Sometimes fails to start, you need to set the startup parameters. Connect power, press and hold the power button for 3 seconds, and the system running, type any key in 3 seconds to enter uboot command line, enter your Selection: e, as following: # setenv bootcmd "movi read kernel C ; movi read rootfs ; bootm C " # setenv bootargs "console=ttysac2, noinitrd root=/dev/mmcblk0p1 rootfstype=ext2 rootdelay=2 rw init=/linuxrc " # saveenv EM210 Linux User Manual 28
