au1200을 사용하고 있구요
wince 5.0 core를 올렸습니다.
부트로더로는 autoboot와 eboot를 사용하는거 같습니다.
wince이미지는 SD카드에서 읽습니다.

증세는 여러가지인데
그중에 심각한문제가 부트로더에서 NK.bin을 읽은다음,
부트 로더에서 WinCE로 넘어가는 도중에 시스템이 멈춥니다.
어떤경우에는 한참후에 CE가 뜰때도 있습니다.
현철님께서는 DDR문제 라고 하셨는데 DDR에서 예전에 문제가 많아서
DDR2로 바꿨다고 합니다.
보드 설계한곳에서는 DDR문제가 아니라고 합니다..

아래는 boot log 입니다만 제일 밑에 Executing Application 이후 넘어가지 않습니다.
