일반 ez-pxa270 mtd 관련 문제

안녕하세요 pxa270 구매를 해서 테스트 하고 있습니다.

mtd  관련 테스트를 하고 있는데

cat /proc/mtd를 하면

[root@falinux ~]$ cat /proc/mtd
dev:    size   erasesize  name

가 나옵니다.  아무래도 mtd 인시하지 못하는 것 같습니다.

커널이 분팅하면서

No NAND device found!!!
No NAND device - returning -ENXIO

이란 메세지를 보내는데 아마도 이것이 원인인 것 같습니다. (보드 결함인가요? 맞다면 택배로 AS를 보내려고 합니다.)

부트로더와 커널이미지 그리고 램디스크는  자료실과 cd 에 있는 것을 둘다  테스트 해보았고 이지부트는 잘 작동합니다.

물론 커널도 mtd를 제외한 다른 것을 잘 작동합니다.
