로그 메시지 상에 뜨는걸로는

예상외로... SD에서 불러오는건 오래 안걸린다?

ramdisk checksum이 오래걸리는건.. 램 퍼포먼스 문제인가..


uboot 1초 대기

커널 + ramdisk 읽기 2초

ramdisk 체크섬 2초

device tree 초기화 1.5초

커널 시작 1초

--


아무튼 커널 부팅까지 9초 정도 걸리는데

이걸 단축할 방법이 안떠오르네..

Wrong Ramdisk Image Format

Ramdisk image is corrupt or invalid

mmc block read, dev 0, addr 0x40008000, blk start 2047, blk cnt 16384

Bad Linux ARM zImage magic!
