혹시나 U2에 쓰던 eMMC를 XU4에 연결했는데 뜨거워지거나 터지진 않았는데 부팅하는 느낌이 전혀 들지 않는다.


히든 파티션에 저장이 안되서 그런가?

[링크 : https://wiki.odroid.com/accessory/emmc/emmc]

회로도를 비교해보는데 솔찍히 회로 상으로는 별반 차이 없는 것 같고 통신 사양을 보기 전에는 단정짓기 힘든 듯.

세부적인걸 찾아보긴 해야 겠지만..

High Speed DDR과 HS400은 Backward Compatibility는 legacy MMC와의 것이었나?

HS400 Host 에서 High Speed DDR이 아니라? ㅠㅠ


eMMC 4.41과 5.0은 dataline 길이가 다르고 시그널 카운트도 다르고

interface로 다른거 보면.. 물리적으로 호환이 되지 않는다고 보면 되려나?

6.0.3 이었나..

rpi2 에서 쓰던거 rpi3에 꽂으니 켜지긴 한데

전에 처럼 H.265 디코딩이 원활하진 않다.


8.0.x 대에서만 rpi3 에서 디코딩이 원활한건가? ㅠㅠ


+

라즈베리 2는 720p25 H.265가 한계라고..

neon 최적화 관련해서 찾아보는데 이렇다할 답은 안보이고

[링크 : https://raspberrypi.stackexchange.com/.../does-raspberry-pi-2-supports-h-265-hardware-decoding]


이전에 테스트 한게 7.0.1이랑 8.0.3 인데

기억이 잘 안나니 다시 7.0.1 깔아서 테스트 해봐야겠네


+

7.0.1 에서 720p h.265 정상 재생 확인

UI 변동이 크면 번거로울 테니 7.0.1로 업그레이드 하는 것으로 결론


라즈베리 2로는 1920*800 에서는 많이 끊어지고 문제가 있네..?

특이하게도(?) 하라는대로 안되서 일단 삐딱선을 타는중

irw로는 eventlircd 에서 잡고 있어서 읽히지 않고 서비스를 죽이면 irw로 읽지 못한다 -_-

그래서 ir-keytable로 읽히는걸 확인

음.. 이 변화가 커널 영향인가 아니면.. 라즈베리 배포판 시기 문제인가..

아무튼 그거와 별개로 커널이 비압축이라 용량이 큰지 SD 메모리 전송 속도로는 한 5초 정도 잡히는 느낌이다

압축 커널이라면 속도가 조금 더 올라갈 듯 한데(프로세서 성능은 충분하니) 

starting kernel 까지 6.7초 정도 쯤(전원 누른 시점으로 부터)

확실히 소비전류가 라즈베리 3에 비해서 무진장 높네

근데 특이사항으로 기가비트라 그런가 랜을 활성화 하면 소비전류가 왕창 늘어난다.

라즈베리 파이 3에는 BLE랑 Wifi가 있는데

환경 설정을 안해줘도 하나도 안 잡히고, 설정해서 KR로 해줘도 안잡힌다.



원인은 찾아봐야겠지만, 이녀석은 왜 오버클럭 설정이 없는거지?


일단 초기 설정 및 KR로 설정시에는 WIFI가 잡히지 않는데, 블루투스는 잡히긴 한다.


검색한대로 US로 설정하니 정상적으로 와이파이가 잡힌다.

    • 잘지내시나요? ㅎㅎ
      일단 블루투스는 핸드폰(갤럭시 노트2)이 문제없이 목록에는 뜨더라구요.
      생각해보니 목록만 확인하고 붙여보진 않았네요.
      블루투스 특성상 profile 지원하는 목록 한계가 있어서 목록에 뜬다 하더라도 기능에 따라 붙는게 제한될순 있는데 확인해봐야겠네요

일단은.. 켠지 2일차!


오드로이드 XU4는

1. 워메 발열 쩔어~

2. 케이스 뚜껑만 따고 쓸수가 없네..

   (케이스와 보드가 고정되지 않고 케이스 상판/하판이 서로 고정되는 구조)

3. heat sink + FAN 조합으로 개조해서 써야하나..

4. 그냥 모양만 낸건가.. 공기 빨아들이기만 겨우 신경쓰고 배출이 안되서 케이스 닫고 쓰긴 부담되네


마우스 옮기는데도 커서가 끊어지는 느낌(설정인가.. 마우스가 문제인가.)

크롬을 통해서 유튜브 보면 720p도 조금 버벅대고 1080p는 못볼 수준

kodi나 lakka 등은 아직 안돌려서 모르겠음


아무튼 케이스 설계 미스로 인해 도무지 쓸 방도가 안떠오르는 계륵 아이템으로 등극..

굳이 쓰려면 새로산 투명 케이스에 heat sink 달고 그 위에 기존 팬을 어떻게 잘 유용해야 할 것으로 보인다

(아니.. 걍 반대로 달면 공기 빨아 들여서 내부도 뜨겁게 되지 않고 좋을거 같은데?)


라즈베리 3B는

일단 케이스가 제꺼가 아니라 이래저래 개조중..

SD 메모리 구멍을 뚫어야 하는데 그냥 한쪽 벽을 허무냐 구멍을 열심히 뚫어 보냐의 기로에서 고민중

(높은 확률로 그냥 한쪽 무너트리는 걸로...)


이유는 모르겠으나 무선랜과 블투가 안되는것 같은데 시간을 들여서 조금 더 조사해 봐야겠다.

    • 케이스에 대한 불만이 가장 큰거 같네요
      케이스만 정상적(?)으로 만들어졌어도 이렇게 불편하지 않았을텐데 하는게 포인트라서요 ㅋ
