SBT-USC1K Drivers    를 설치 후 시리얼을 꽂는다

그 다음 테라텀 실행하고 시리얼 보면
아래와 같은 com 포트가 생김

시리얼로 일단 연결해놓고 전원이랑 usb를 꽂으면 부팅이 시작됨
이때 키보드를 존나게 눌러야 u-boot로 부팅됨

이게 부팅 화면

kermit -s beagle.bin
하면 보낼준비됨

간단하게 얘기하면
서버에서 kermit -s 파일명 하고 file - transfer - 0kermit receive로 바탕화면에 파일전송
그 다음 uboot 화면에서 loadb 82000000 함
그리고 uboot화면에서 kermit send 바탕화면 파일 선택하면 전송됨

----------------------
이 보드에서 reset은 메모리 내용이 사라지진 않는다..reset exception을 발생해서 재부팅하는거
파워를 뺏다가 한 1분뒤에 부팅하면 없어진다


bin 파일은 숨겨진 파일이 될 수 있으니깐 폴더옵션에서 보이게해놔

.s 파일은 어셈블러 파일 이라고 정하자...저번에는 .asm 이었는데
