Thanks for all the help. It turned out that using "fastboot boot my_zImage" would boot the N1 just fine. So my problem is not in the kernel but rather in the Android image. It should be a question for another discussion board. doug -- unsubscribe: android-kernel+unsubscr...@googlegroups.com w

Hi, Danke Thanks for reply. I'm porting the kernel-msm-.32 on my Tattoo. It has msm7225 board with QVGA screen, which is not supported by android. The board driver was written by HTC for 2.6.29-msm kernel. It seems that to use 2.6.32 kernel on this device, I must port the board driver to kernel-m
