저는 SOC 플랫폼에서 u-boot(2013-07)를 부트로더로 사용하여 임베디드 Linux 시스템에서 작업하고 있습니다. 이제 u-boot에서 USB 디스크를 지원하려고 하므로 일부 포팅과 하드웨어 구성을 수행했습니다.
나생각하다usb startu-boot는 USB 플래시 드라이브를 감지할 수 있지만 명령줄에서 실행할 때 오류가 발생합니다.
오류에 대한 자세한 정보를 얻기 위해 DEBUG 및 BBB_XPORT_TRACE를 활성화했는데 common/usb_storage.c오류가 발생했습니다(이 SOC의 CACHELINE_SIZE는 32입니다).

1000ms 지연을 추가하려고 시도했지만 usb_stor_BBB_transport()효과가 없었습니다.
저는 U-boot의 USB 스택을 처음 사용하는데, 이 오류의 가능한 원인은 무엇입니까? 문제를 해결하려면 어떻게 해야 하나요?
작동 중인 SOC의 로그로 업데이트
유사한 SOC에서 u-boot 코드베이스를 시도했는데 작동합니다. 다음 로그를 얻었 usb start는데 그러한 오류가 없습니다 . STATUS phase즉, 오류가 발생하지 않습니다 CSWSIGNATURE.
