처음으로 인사드립니다. 제 이름은 민경오이고요. 현재 S3C6410 Baord에 Linux를 올려서 작업 중입니다.
우선 홈지기께서는 2.6.28 Kernel을 이용해서 부팅하셨다고 봤고요. 로그도 보았습니다. 아래는 현재 제가 겪고 있는 문제의 로그고요
아래 보시면 Starting Error가 있는데, 결국 문제는 0x74300000의 가상 주소를 받아서 처리 하는 부분 같은데,
static int ohci_run (struct ohci_hcd *ohci) 함수 내에서 ohci->regs의 주소가 0xC8E00000를 받는데, 이부분에 write가 되지 않습니다.
제가 리눅스 쪽은 초보이고 며칠째 작업 중이라 해결이 안되어 문의 드립니다. 혹 아시는 정보 있으시면 공유 부탁드립니다.
추가로 JTAG에서 A:0x74300000에 direct write를 하려해도 값이 변경되지 않네요. 어떤 다른 조건이 있을까요?
