android에서 USB GPS Module 확인 방법

hardkernel에서 판매 중인 USB GPS Module입니다.

http://www.hardkernel.com/main/products/prdt_info.php?g_code=G142502154078

ODROID에 연결하면 아래와 같이 /dev/ttyACM0 노드가 생깁니다.

root@odroidxu3:/ # ls -l /dev/ttyACM0
crw-rw-rw- gps gps 166, 0 2015-03-19 16:46 ttyACM0

cat으로 노드를 읽어 보면 NMEA 값이 출력이 됩니다.

KODI for ODROID-C1

KODI is pre-installed on ODROID-C1 1.2 version.

http://odroid.com/dokuwiki/doku.php?id=en:c1_android_release_note_v1.2

But KODI is not working well because KODI is denied by Superuser.

KODI need SuperSU apps instead Supersuser app.

Settings => Language & input

Turn off Hardware Physical keyboard.

It you want to work IR remote, Turn on after settings.

Download GApps Installer for KitKat.

Install GApps Installer app.

Allow and wait to reboot.

Market installed.

Install SuperSU app.

Continue

Normal

Remember choice forever and Allow.

How to make Installer for ODROID-XU3

Insert microSD/eMMC to PC.
Check media node name.
$ sudo fdisk -l

Fill zero data to media.
$ sudo dd if=/dev/zero of=/dev/sdX bs=512 count=1024000

Run Gparted.
menu -> Device -> Create Partition Table...

menu -> Partition -> New

Free space preceding (MiB) 100

New size (MiB): 400

File system: fat32

Apply All Operations

fuse u-boot binaries for SD media.

https://github.com/codewalkerster/android_device_hardkernel_odroidxu3/tree/5422_4.4.4_master/uboot

$ cd device/hardkernel/odroidxu3/uboot

$ sudo sh sd_fusing.sd /dev/sdX

mount fat32 partition.

copy bl1.bin, bl2.bin, tzsw.bin, u-boot.bin files to mounted partition.

$ cd out/target/product/odroidxu3/update/

copy zImage-dtb, system.img, userdata.img, cache.ing to mounted partition.

copy boot.ini file too.

http://dn.odroid.com/5422/ODROID-XU3/Android/boot.ini/

sync and umount.

dump image.

$ sudo dd if=/dev/sdX of=./sd_installer.img bs=512 count=1024000

Extract img file and make checksum by md5sum.
