You should configure PPCBoot properly to match the kernel. This has been configurable for a long time. See the PPCBoot README re CONFIG_CLOCKS_IN_MHZ. It has been discussed many times on the ppcboot-users list, for example see: http://sourceforge.net/mailarchive/message.php?msg_id=479868 BTW clocks_in_mhz must be _removed_ from the environment to get the clocks in HZ. Setting the value 0 does not work. Dave Dave Ellis ~~~~~~~~~~~~~~~~~~~~~~~~~~ SIXNET - "Leading the Industrial Ethernet Revolution" 331 Ushers Road, P.O.

Here are my configurations Processor -> MPC823 Board -> FADS823 Available RAM -> 0x000 to 0x 800000 Linux kernel Linked at -> 0x40000 mkimage on kernel done with Load address -> 0x40000 mkimage on kernel done with Entry point -> 0x4000c mkimage on RAMDISK done with Load Address -> 0x100000 mkimage on RAMDISK done with Entry point -> 0x100000 >From u-boot command prompt, I do the following > tftpboot 40000 linux.img > tftpboot 100000 ramdisk.img > bootm 40000 100000 It says successful loading kernel , as well as RAMDISK. But after which, I do not get any further Linux banneers. In fact, the Linux kernel 's printfs aren't seen. I set the env variable bootargs as /dev/ram.. But in any case, only after the kernel boots up and the VFS is initialized, the Rootfs is going to come into picture, right ?? Any clues.... Rupesh ** Sent via the linuxppc-dev mail list.

You asked on the U-Boot mailing list already, and received a reply semi-immediately. Only 7 minutes after your first posting you asked again. And now you post the same stuff a third time on linuxppc-embedded? As long as you are asking for free support you should show a little more patience. [And even with commercial support you probably cannot get guaranteed solutions in less than 5 minutes.] Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd@denx.de Mistakes are often the stepping stones to utter failure. ** Sent via the linuxppc-dev mail list.
