안녕하세요..

mkdir 로 만드는것이 맞습니다.

에러가 발생하는 것은 NAND 플래쉬에 문제가 있거나 아니면 다른 문제가 있을 수 있습니다.
일단 다음과 같이 해 보시고 같은 에러가 발생하면 보드를 A/S 보내 주세요.

1. EZ-X5 + PI 보드를 사용하신다면 전원 12V/1A 이상을 사용하시나요??

2. 부팅 후 mkdir로 디렉토리를 만들어 보세요.

    EZBOOT> nea

3. 부팅 후 mkdir로 디렉토리를 만들어 보세요.

4. 같은 에러가 발생하면 EZ-X5 보드와 EZ-PI 보드를 분리하시고, EZ-X5의 커널과 램디스크를 올리세요.
    이때 전원은 EZ-X5 보드에 5V/1A 이상의 전원을 사용하시거나 제공된 USB 케이블을 이용하세요.

5. 부팅 후 mkdir로 디렉토리를 만들어 보세요.

    EZBOOT> nea

6. 부팅 후 mkdir로 디렉토리를 만들어 보세요.


그럼 수고하세요.
