thanks Maupin a lot! My boot envirment is: DM355 EVM # printenv bootdelay=3 baudrate=115200 bootfile=uImage bootcmd=nboot 0x80700000 0 0x400000;bootm 0x80700000 filesize=17f888 fileaddr=80700000 ipaddr=10.0.0.53 bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=10.0.0.89:/nfs/restore_dm355,nolock mem=116M video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16, 2500K:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=pal serverip=10.0.0.89 stdin=serial stdout=serial stderr=serial videostd=pal Environment size: 491/16380 bytes
The demo uImage-dm355 can be boot up,but the new kernel i compiled can't been boot, The console show only bootloader information,no kernel information.I am amazed ! 2009-05-14 zuowenping 发件人： Maupin, Chase 发送时间： 2009-05-13 21:22:04 收件人： Steve Chen; zuowenping 抄送： davinci-linux-open-source 主题： RE: I can't boot linux2.6.18 uImage in dm355 Also, check you console setting in your u-boot bootargs variable. This looks like what happens when the console isn't setup right. Once control is given over to the kernel it does not know how to output the console messages. Please include your u-boot environment variables in your next e-mail.
