OK, I built 2.6.20.11 and 2.6.21.1 for taiga...with the supplied config (and I didn't know about the dtc for powerpc until I booted and nothing happened). I changed a few things (like /proc/config.gz)
A few issues I've seen: 1) after we start booting, the console turns off until the login message appears: taiga login: [ 0.000000] Zone PFN ranges: 000000] Normal 131072 -> 131072 [ 0.000000] early_node_map[1] active PFN ranges [ 0.000000] 0: 0 -> 131072 [ 0.000000] Built 1 zonelists. Total pages: 130048 [ 0.000000] Kernel command line: root=/dev/sda2 console=ttyS0,11520 [ 0.000000] mpic: Setting up MPIC "Tsi108_PIC" version 1.2 at c0007400, max 4 CPUs [ 0.000000] mpic: ISU size: 24, shift: 5, mask: 1f [ 0.000000] mpic: Initializing for 24 sources [ 0.000000] PID hash table entries: 2048 (order: 11, 8192 bytes) Linux System Kernel 2.6.21.1 on an ppc Version: #2 Thu May 24 14:37:53 EDT 2007 This is consistent on 2.6.20.11 and 2.6.21.1... 2) Does "reboot" work? Even when I do a <sysrq-magic-b> it doesn't want to boot until I do a hardware reset.... 3) It seems 2.6.21.1 consistently works, 2.6.20.11 sometimes hangs (and since I can't see the console, I don't know what's hanging and why) 4) The dtb strategy seems to a little clumsy...is there a way to embed a default dtc into a kernel (so if you just tftp one file, something happens?) I like the ability to do fewer operations (i.e. initramfs embedded in the image) -- I like reducing steps into of increasing them... Is there a way to tell the kernel "use a default dtb if you don't have one better?" marty _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
