Unpacking Android sources

$ cd ${workspace}
$ chmod +x walkthrough.sh
$ HAVE_ADSP=NO ./walkthrough.sh H3

Building the BSP for R-Car Starter Kit Premier(H3)

Please check additional build options and apply any if needed prior to starting the build process.

$ cd ${workspace}/mydroid
# Set Android build environment
$ export TARGET_BOARD_PLATFORM=r8a7795

# Please set H3_OPTION variables. 
# 4GB DDR case
$ export H3_OPTION=4GB
# 8GB DDR case
$ export H3_OPTION=8GB

$ source build/envsetup.sh
$ lunch kingfisher-userdebug
$ export BUILD_BOOTLOADERS=true
$ export BUILD_BOOTLOADERS_SREC=true
$ make

Copying images file

$ export images_dir=<your_images_dir>
$ mkdir ${images_dir}
$ cp \

Flashing binaries

Flashing IPL

Flashing SREC bootloader files

It's needed to update the Loader, ARM Trusted firmware, Certification, OP-Tee and u-boot in the QSPI Flash memory as it's described in R-Car/Boards/H3SK#Flashing_firmware.

Flashing images using fastboot

Note: this step should be done after successful IPL and U-Boot flashing.

# 0. Connect host and board via USB debug port and start minicom:
$ sudo minicom -D /dev/ttyUSB0

# 1. Turn on the device and interrupt autoboot by pressing any key when device starts booting up.

# 2. Erase bootloader in eMMC 
=> mmc dev 1 1 
=> mw.b 4f000000 0 200000 
=> mmc write 4f000000 0 1000 
=> mmc dev 1 2 
=> mw.b 4f000000 0 200000 
=> mmc write 4f000000 0 1000 
=> reset 
# Please interrupt autoboot 

# 3. Reset default environment:
=> env default -a

# 4. Set ethernet hardware address (written on Ethernet port):
=> setenv ethaddr <board MAC addr>

# 5. Set board serial number of R-Car Starter Kit
=> editenv serialno 
Edit: serialno=xxxxxxxx 
# Padding 0 for a total of 8 digits
=> editenv bootargs 
=> video=VGA-1:d init_time=xxxxxxxxxx 
#”video” variable needs to set parameter related to display configuration.
#”init_time” variable needs to set UNIX time. 
#You can get it by executing “date +%s” command on host PC. 
#The board don't have any RTC. 
#If time and date is not accurate, a few issues will be happened. 

# 6. Save changes:
=> saveenv

# 7. And reboot the device:
=> reset

# 8. After reboot activate fastboot mode by running “fastboot” in u-boot environment:
=> fastboot
# Next commands are performed on host side:
$ cd ${images_dir}
$ chmod a+x ./fastboot 
$ chmod a+x ./fastboot.sh 

# 9. Create GPT table on eMMC:
$ sudo ./fastboot oem format

# 10. Reboot device into bootloader:
$ sudo ./fastboot reboot-bootloader

# 11. Go to images directory and execute:
$ sudo ./fastboot.sh --noresetenv

Booting device

1) Connect Monitor to microHDMI(CN4) port in Starter Kit board(Mandatory).
2) Connect Starter Kit board to host PC via debug port(CN12).
3) Connect usb cable to Kingfisher OTG(CN13) for adb debug.
4) (Optional) Connect Ethernet cable(CN7).
5) Power on device.
6) Wait until Android boot is completed.

Tips

Screen configuration

Resolution parameters

By default HWComposer selects resolutions not higher than Full HD with display aspect ratio.

#  Turn on the device and interrupt autoboot using minicom.
# Edit environment variable:
=> editenv bootargs
# Set video resolution:
# for display connected to Starter Kit:
  androidboot.display.res.HDMI2=1280x720-32@60
# for display connected to Kingfisher
  androidboot.display.res.HDMI1=1280x720-32@60
# for LVDS display on Kingfisher
  androidboot.display.res.LVDS=1280x720-32@60
# Save changes:
=> saveenv

Measuring FPS on HWC level

To enable fps show:

$ adb shell setprop debug.hwc.showfps 1

Fps values can be found in logcat log like:

...
hwcomposer: fps: 22.0 (23 frame per 1.043099 sec)
...

To disable fps show:

$ adb shell setprop debug.hwc.showfps 0

Microphone level amplification

By default, audio volume may be low when recording from the microphone. This can be affected by using a microphone preamplifier integrated into KF extension.
Microphone preamplifier is equipped with three switches (SW3, SW4 and SW5). Every switch contains two toggles, responsible for the left and right audio channels. Turning on the toggle will provide the microphone amplification by 20dB.
