ADSTAR SDCard Boot 시 각종 에러 발생 문제

SD Card를 사용하여 Boot를 하는 경우 지켜져야 하는 조건이 있는 것 같습니다.

 

USB Host를 사용하면 USB_OVC에 100k옴을 달아줘야 하는 것 같습니다.

10k옴을 달았더니 아래의 에러들이 랜덤하게 발생했습니다. (100k옴으로 변경 후 계속 발생하지 않는 걸로 보아 해결된 것으로 보입니다. 아마...=> 계속 테스트 하고 있었는데 3일 만에 나와버리고 말았습니다. => 현재까지는 MCU 변경하다보니 발생하는 MCU가 있고 발생하지 않는 MCU가 있어서 MCU 교체로 해결하고 있습니다.) 

내부 플래쉬에 라이팅하는 경우에는 발생하지 않았고, USB Host를 사용하지 않거나 SD Card 포맷시 설정(8192로 하면 동작하고 16kb로 하면 바로 에러가 발생하고 등등)에 따라서 발생 빈도도 다르고 그래서 더 어려웠습니다. 혹시 같은 문제를 겪는 분이 계시면 저항값 변경 부터 해보면 될 것 같습니다.
