As I see from your patch you changed it to be 0x01008000 instead. So you should probably either load the kernel to this address, or change the corresponding KERNPHYSADDR parameter to 0x200000. Does this board has JTAG port available? It will make the debugging much easier. --=20 Stanislav Sedov ST4096-RIPE --Signature=_Fri__25_Sep_2009_17_20_49_+0400_euEB_6gJnnEWpimv Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- iQIcBAEBAgAGBQJKvMOxAAoJEKN82nOYvCd0mQYP/1dMotcqVHqpfsNsN4mfU+xu oz/d1hHmVQa0LtFmQ+4SHFZDcWNRuzU1pmB7QO28mSKTSGI4qN3c5q7UuvHOVzvf avtZXqGm0IXxhy88xauMAfeHNapQC8z36XBK6e0PSC+m1VSo+f7L3KcnvLoELL2o DuwxMd7+r+j4pAJCat65sxFBGAtDNfyssNoJbWFQrwXcq6G34LpuZqq4ryqC+FlN rmSvYzeyVN1nDCtyWkSU2QPzdcHZKwzucP5rLGgvRjSEOq8PVGOQIF3EbJ6k/bD0 yV6TzfTcIvO/9OlSJiGYOVnIEAWFih/+L3Eh0hrgn88QMlEavvdlaw3n+bETMIB+ 2enZmTWJkSSjZHLlibo2uArhJAOzHGT5zzuzbz3sJhCJ3UThMpir6HFqX1kyQ+fo nnw0ZsjBumSzVnOW95BnjY45Sd3BkYi6AlZNmStbMFp6keHq8BIAiSGxKKYu2IEc FezwdJcO9h1ca2V4MkPV9sp8jhp9uNqXz6V9LeXzyqNAdUL011B/vpxLyc2XyUs9 VUMDYB93tJSuPuif5NW8aTCLkFqUfXaR50tvrMPyC4g634Xpg9/gWii2QN8UC6qc ST22JYkZfePZ3NSSb+zJD45isFG5QsynyOSbYPseUSLGcCZXSymqBrtr+ekBSBG/ p77wSjc58tc6IqjnPWr8 =SX1Z -----END PGP SIGNATURE----- --Signature=_Fri__25_Sep_2009_17_20_49_+0400_euEB_6gJnnEWpimv--
