Well, I got the thing to boot, though now I don't quite understand it. I ended up changing the address used in zsrec and the "go" address to "0x90000" instead of "0x900000". I saw the memory map in the DINK32 manual that the "Start of user memory" is at 0x90000. I figured it was a typo in the HHL CDK manual. So, life was good. Until I realized the bootloader relocates to 0x80000. Now I'm confused again.
DINK32_MAX >>go 90000 loaded at: 00090000 000A4E20 relocated to: 00800000 00814E20 zimage at: 0009B000 0011B486 relocated to: 00815000 00895486 avail ram: 00400000 00800000 Since "avail ram" is 400000-800000, should I run srec -s (something < 800000)? I know I read that it should be higher than the relocated image ... Do these numbers just depend on the amount of ram present?? confused, Mark -----Original Message----- <newbie alert!> I've just undertaken trying to get a Sandpoint 8240 to boot ppc linux. I have the mvista CDK 1.2, as well as the code from ftp://ftp.mvista.com:/pub/Area51/sandpoint-8240/README My development platform is RH6.2 linux. I'm running version 12.0 of DINK. Here come the questions :) 1) I tried compiling the code in spdemo-2.3.16-2000.02.10, but it insists on a ramdisk.image.gz file. I tried removing the RAMDISK entry from .config, but them got compile errors. I see instructions on how to build a ramdisk, but - how do I put the right ppc files in the ram disk if I don't have a ppc system to get them from? 2) I resorted to compiling the linux-2.4.0-test2 kernel, and it compiled with the additional network card I needed (tulip). However, when I boot, I get DINK32_MAX >>go 900000 loaded at: 00900000 00914E20 relocated to: 00800000 00814E20 zimage at: 0090B000 00988955 avail ram: 00400000 00800000 Linux/PPC load: root=nfs Uncompressing Linux...done. Now booting the kernel and that's it. What should I see next? Should it init the network card? Will I see that? I have dhcp, tftp, nfs set up but I don't see any network activity on the host from the sandpoint using tcpdump. thanks for any pointers! Mark ** Sent via the linuxppc-embedded mail list.
