[VistaCube] Quick Android/Linux Porting Guide.

Published by Jin Park on

This post describes how to port Vista Cube™ for RDC200/RDP550F initialization using 1)Linux console application or 2) Android Java Application.

We assume that our porting environment is on Android Linux and our target products are RDC200/RDP550F and you already setup a display driver for them.

Case 1) Linux console application

Take step by step!!

  1. Download a VistaCube.zip on our our dev-site. And extract the password protected zip-file into the appropriate location on your host computer.
    • You need to know the password. If you don’t know, contact us.
  2. Include our RAONTECH i2c(rtimd-i2c) driver module into our linux system.
    • Copy $VISTA_CUBE_PATH/src/linux_driver/rtimd-i2c/ into $KERNEL_PATH/drivers/misc/
    • Write  source drivers/misc/rtimd-i2c/Kconfig into $KERNEL_PATH/drivers/misc/Kconfig/
    • Write  obj-y += rtimd-i2c/ in $KERNEL_PATH/drivers/misc/Makefile
    • Apply the driver module to your kernel
      • sudo make menuconfig in $KERNEL_PATH/
      • Navigate : Device Drivers -> Misc devices -> RAONTECH Micro Display I2C support
      • Check all sub-menu items
    • Set permission for the driver module on init.rc
      • chmod 755 /dev/rtimd-i2c
    • Build your kernel and then boot with it
  3. Set your ndk-path in $VISTA_CUBE_PATH/src/test/android/build_android.sh
    • e.g. NDK_SRC_DIR=“/Users/jpark/Library/Android/sdk/ndk-bundle”
  4. Check/Configure the following settings in according to your target system  
    • enable flags :$VISTA_CUBE_PATH/src/test/android/Android.mk
      • USE_VC_DEBUG_MSG := y
      • USE_MDC_RDC200 := y
      • USE_PANEL_RDP550F := y
    • i2c bus number : $VISTA_CUBE_PATH/src/libvc/include/rti_vc_config.h
      • _CFG_I2C_BUS_NR_RDC_RDP0    6
      • _CFG_I2C_BUS_NR_RDC_RDP1    1
    • Check if a path is accessible or not : $VISTA_CUBE_PATH/src/test/test.h
      • #define RDC200_LUT_FILE_PATH "/data/vclut/rdc200"
  5. Download an appropriate init file ( RDC100 init file / RDC200 init file) in according to your target. And extract it into an appropriate location on your host computer.
  6. Write the whole path you want to download in rdcxxx_download_file_list.txt
    • e.g  in  $INIT_FILE_PATH/download/rdp550f/rdc200_download_file_list.txt
    • NOTE : The path (/data/vclut/rdc200) must match up with that wrote in the step 4.
      • 0 /data/vclut/rdc200/rdc200_fw_v1.5_gpioB_20171010.hex
      • 1 /data/vclut/rdc200/fw_rdc200.cfg
      • 2 /data/vclut/rdc200/init_rdc200_R1_F5_rdp550f-e_20170614.rega
      • 3 /data/vclut/rdc200/init_rdp550f-e_20170405.rega
      • 4 /data/vclut/rdc200/20170406_gamm2.0.lut
      • 10 /data/vclut/rdc200/bootlogo_00.bmp
  7. Copy the init files including rdcxxx_download_file_list.txt into your target platform
    • e.g  in your host computer
      • adb shell mkdir -p /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/download/rdp550f/fw_rdc200.cfg /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/download/rdp550f/rdc200_download_file_list.txt /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/feature/rdc200_fw_v1.5_gpioB_20171010.hex /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/feature/20170406_gamm2.0.lut /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/feature/bootlogo_00.bmp /data/vclut/rdc200
      • adb push $INIT_FILE_PATH/init_lut/rdc200/init_rdc200_R1_F5_rdp550f-e_20170614.rega /data/vclut/rdc200
      • add push $INIT_FILE_PATH/init_lut/rdp550f/init_rdp550f-e_20170405.rega /data/vclut/rdc200
  8. Check the path you put the init files on $VISTA_CUBE_PATH/src/test/test.h
    • #define RDC200_LUT_FILE_PATH /data/vclut/rdc200
  9. Start vctest app and then download on CLI
    • cd $VISTA_CUBE_PATH/src/test/android
    • chmod u+x build_android.sh
    • ./build_android.sh
    • adb push libs/arm64-v8a/vctest /data
    • adb shell
    • cd /data
    • ./vctest
    • Download followings
      • 0 ↵ # Firmware image
        • 0 ↵ # [0]: /data/vclut/rdc200/rdc200_fw_v1.5_gpioB_20171010.hex
      • 1 ↵ # Firmware Configuration
        • 0 ↵ # [0]: /data/vclut/rdc200/fw_rdc200.cfg
      • 2 ↵ # RDC init LUT
        • 2 ↵ # [2]: /data/vclut/rdc200/init_rdc200_R1_F5_rdp550f-e_20170614.rega
      • 3 ↵ # RDP init LUT
        • 3 ↵ # [3]: /data/vclut/rdc200/init_rdp550f-e_20170405.rega
      • 4 ↵ # Gamma LUT
        • 0 ↵ # [0]: /data/vclut/rdc200/20170406_gamma2.0.lut
      • a ↵ #  Bootlogo image
        • 0 ↵ # [0]: /data/vclut/rdc200/bootlogo_00.bmp
  10. After finishing step 9, reboot. Then you will see your platform’s default screen on our display panels.

Case 2) Android Java Application

  1. Same as the above.
  2. Same as the above.
    • But there could be android permission issue.
      1. For testing, you can disable it temporarily:
        • adb shell setenforce 0
        • adb shell chmod 777 /dev/rtimd-i2c
      2. Or you can avoid it when build kernel
        • Write /dev/rtimd-i2c u:object_r:rtimodule_device:s0 in$ANDROID_SRC_PATH/external/sepolicy/file_contexts
        • Write type rtimodule_device, dev_type; in $ANDROID_SRC_PATH/external/sepolicy/device.te
        • Write allow untrusted_app rtimodule_device:chr_file rw_file_perms; in $ANDROID_SRC_PATH/external/sepolicy/untrusted_app.te
        • Write chmod 0777 /dev/rtimd-i2c in $ANDROID_SRC_PATH/system/core/rootdir/init.rc
  3. Build Android Java App
    • cd $VISTA_CUBE_PATH/src/test/android_app/
    • PATH=$PATH:/Users/jpark/Library/Android/sdk/ndk-bundle
    • ndk-build
    • Import existing android project ($VISTA_CUBE/src/test/android_app) into Eclipse SDK
    • Build and then install the output apk into your target platform
  4. Same as the above.
    • Check if a path is accessible or not : $VISTA_CUBE_PATH/src/test/test.h
      • #define RDC200_LUT_FILE_PATH "/sdcard/Movies/vclut/rdc200"
  5. Same as the above.
  6. Add the whole path you want to download in $INIT_FILE_PATH/download/rdpxxx/rdcxxx_download_file_list.txt
    • NOTE : The path (/sdcard/Movies/vclut/rdc200) must match up with that wrote in the step 4.
    • 0 /sdcard/Movies/vclut/rdc200/rdc200_fw_v1.5_gpioB_20171010.hex
      1 /sdcard/Movies/vclut/rdc200/fw_rdc200.cfg
      2 /sdcard/Movies/vclut/rdc200/init_rdc200_R1_F5_rdp550f-e_20170614.rega
      3 /sdcard/Movies/vclut/rdc200/init_rdp550f-e_20170405.rega
      4 /sdcard/Movies/vclut/rdc200/20170406_gamm2.0.lut
      10 /sdcard/Movies/vclut/rdc200/bootlogo_00.bmp
  7. Copy the init files including rdcxxx_download_file_list.txt into your target platform
    • adb shell mkdir -p /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/download/rdp550f/fw_rdc200.cfg /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/download/rdp550f/rdc200_download_file_list.txt /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/feature/rdc200_fw_v1.5_gpioB_20171010.hex /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/feature/20170406_gamm2.0.lut /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/feature/bootlogo_00.bmp /sdcard/Movies/vclut/rdc200
    • adb push $INIT_FILE_PATH/init_lut/rdc200/init_rdc200_R1_F5_rdp550f-e_20170614.rega /sdcard/Movies/vclut/rdc200
    • add push $INIT_FILE_PATH/init_lut/rdp550f/init_rdp550f-e_20170405.rega /sdcard/Movies/vclut/rdc200
  8. Check the path you put the init files on $VISTA_CUBE_PATH/src/test/test.h
    • #define RDC200_LUT_FILE_PATH "/sdcard/Movies/vclut/rdc200"
  9. Start the installed android app (in Step3) and then follow below.
    • Select Controller ComboBox to be RDC200
    • Select Panel ComboBox to be RDP550F
    • Click APPLY button ( It shows a list of downloading file)
    • Click DOWNLOAD button ( It will take some time )
  10. Same as the above.
