T32같은 JTAG 장비가 없쪄서..ㅡㅡ;

OpenOCD와 FT2232를 이용해 JTAG 연결을 해볼라구 했는데.ㅡㅡ;

힘들군요 ㅠ.ㅠ 좌절만땅,

OneNAND가 뭐신가에 uboot라도 올려보고자 하는 건... 너무 큰 욕심인가요 ㅠ.ㅠ

ODROIDT Debug board에서 JTAG 신호들을 찾아내서 FT2232쪽 Jtag포트와 연결 

TP1 nSRST

TP2 nTRST

TP3 TMS

TP4 TCK

TP5 TDI

TP6 TDO

openocd 컴파일은 http://jejsk.tistory.com/19 를 따라했고, usb FT2232 인식까진 되는 듯

그러나 타겟 디바이스를 어떻게 인식 시켜줘야하는지...ㅠ.ㅠ

 ㅡㅡ; 어렵다 어려워
