odroid u2 크롬이 느리네..(창 그리기)

내용을 찾아 보니.. 크롬에서 자기네가 지원안하는 기능으로 한거 같다는 내용

[링크 : http://com.odroid.com/sigong/nf_board/nboard_view.php?brd_id=odroidu2&kind=...&bid=4028]

집에와서 해보니.. 파이어폭스도 느리다.

특정 openGL ES 관련해서 지원이 부족한 걸지도...

140 나오면 정상이라는데

exynos 드라이버 읽지 못하는 듯..

$ glxgears
libGL error: MESA-LOADER: malformed or no PCI ID
libGL error: dlopen /usr/lib/arm-linux-gnueabihf/dri/exynos_dri.so failed (/usr/lib/arm-linux-gnueabihf/dri/exynos_dri.so: cannot open shared object file: No such file or directory)
libGL error: dlopen ${ORIGIN}/dri/exynos_dri.so failed (${ORIGIN}/dri/exynos_dri.so: cannot open shared object file: No such file or directory)
libGL error: dlopen /usr/lib/dri/exynos_dri.so failed (/usr/lib/dri/exynos_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: exynos_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: exynos
729 frames in 5.0 seconds = 145.617 FPS

openGL은 지원하지 않고 openGL ES(EGL)만 지원해서 그렇다고?

[링크 : http://forum.odroid.com/viewtopic.php?f=77&t=13251]

odroid-utility.sh를 통해서 업데이트 해도 여전히 exynos_dri.so가 없다고 나온다 -_-

odroid u3 한글 입력

preference - language support 하라는데

꽤 오래걸리네..

온갖 각국언어 다 깔리는 구만 -_-

원하는 것만 선택해서 깔아야지 -_-

[링크 : http://com.odroid.com/.../nboard_view.php?brd_id=odroidxuthree&bid=5179]

[링크 : http://ngee.tistory.com/326]

일단은 해보니...

14.04 LTS odroid 버전인데..

keyboard input method 쪽과 언어 지원을 건드리면 어떻게 되는 듯 한데..

조건을 잘 모르겠네...

class 10 UHS-1 이라도 같은게 아닌가?

예전에 라즈베리에서 쓰던게...

80MB/s 짜리 검은색 Ultra class 10 UHS-1 이었나 본데..

새로 산건

48MB/s 짜리 흰/회색 Ultra class 10 UHS-1 인 듯..

젠장 -_-

라즈베리에서 쓰던 녀석을

odroid에 하니 날아 다닌다 -_-

확실히... 라즈베리 파이 2b 대비 드럽게 느리다.

무슨 차이지?

odroid u3는 SDHC..

아.. 웬지 눙물난다 흑흑 UHS-1 쓸수 있다 아싸 하면서 샀더니 흑흑 ㅠㅠ

SD High Capacity (SDHC™) card is an SD™ memory card based on the SDA 2.0 specification.

SDHC capacities range from 4GB to 32GB

Default Format: FAT32

[링크 : http://kb.sandisk.com//.../sd%2Fsdhc%2Fsdxc-specifications-and-compatibility]

exynos 4 시리즈는 2.0 이고 5 시리즈 부터 3.0 인 듯..

HS-MMC/SDIO Interface supports:

 Multimedia Card Protocol version 4.3 compatible (HS-MMC)

 SD Memory Card Protocol version 2.0 compatible

 DMA based or interrupt based operation

 128 word FIFO for Tx/Rx

 Four ports HS-MMC or four ports SDIO

[링크 : http://www.samsung.com/.../Exynos_4_Quad_User_Manaul_Public_REV1.00-0.pdf]

+

음.. 일단 HS-MMC는 50MHz에 8bit로 구성한걸려나?

[링크 : http://www.samsung.com/.../Exynos_4_Quad_User_Manaul_Public_REV1.00-0.pdf]

그렇다면.. 벤치상으로는 초당 52MB/s 정도는 쓸 수 있다는 건가?

SDHC라서 초당 14MB/s 정도가 한계인데 확실히 여유가 생길 듯..

[링크 : http://read.pudn.com/.../hs_mmc_application_note_050111.pdf]

MMC0/1 8bit 이게무슨 의미일려나..

eMMC 39MB/s vs SDHC 15MB/s - oroid x2(exynos4412-u3와 동일 모델)

eMMC

SDHC

[링크 : http://forum.odroid.com/viewtopic.php?f=54&t=1152]

4.2나 4.3이나 속도 차이는 없는 52MB/s 이고

4.4가 되어야 DDR 지원하며 100MB/s를 찍는 듯

For its specification, eMMC 4.2 defines the eMMC’s interface capacity (larger than 2GB) and speed (52MB/s); eMMC 4.3 provides new functions of Booting Function, Explicit Sleep Mode, Reliable Write, etc.; and the latest eMMC 4.4’s double data rate (DDR) is strengthened, which increases the original 52MB/s to 100MB/s
