[질문요..] nfs 마운트하고 init실행시 문제....

<pre><font size=2> cs8900그런대로 문제를 비켜나갔는데... nfs용 디바이스로 등록을 시키다가 쭉 뻗는 문제는 해결했는데... nfs root에서 init를 읽어오고 나서 완전히 난리네요... 일단 패킷은 확실히 지나다니는걸 확인잘 했습니다만... 혹시 nfs 포팅하신분중에....다음과 같은 걸 해결하신분 계시면 답변 부탁바랍니다...^^ ========================================================= U-Boot 0.4.0 (Oct 16 2003 - 13:17:39) U-Boot code: 33F80000 -> 33F96AB4 BSS: -> 33F9A53C DRAM Configuration: Bank #0: 30000000 64 MB Get flash bank 0 size @ 0x0 Manuf.
