odroid XU4 + U3 eMMC 4.41 부팅

호환 안된다고 했지만 막상 해보니 되긴 하는 듯

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

일단은 확인을 위한 사진

파란색의 eMMC v0.3 U3 에서 사용하던 8GB 짜리 녀석이다.

걍 확인겸(?) 방열판 떼고 굳어 버린 써멀 구리스 닦아내고 가지고 있던거 다시 발라주었는데

날씨 탓인가 확실히 팬이 덜 도는 느낌이다.

그런데 영 빠른 느낌은 안드는것 같기도 하고..

조금 걸리는 듯이 느껴지던 zImage와 uInitrd 로딩이 걸림없이 바로 넘어가 checksum 까지 1초 가량 단축되었다.

그리고 로그인 화면까지 25초 정도 (기존에 35초 걸렸던거 같은데?)

빨라지긴 했으나 eMMC를 써도 획기적으로 줄진 않네.. eMMC 4.41 버전이라 그런건가?
