Re: 2.6.25-rc3 on mpc8548amc doesn't boot
Hi, I have a question for submitting my changes: As I said I have commented a few line in arch/powerpc/boot/Makefile #$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 #$(obj)/ebony.o: BOOTCFLAGS += -mcpu=405 #$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=405 #$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=405 #$(obj)/treeboot-walnut.o: BOOTCFLAGS += -mcpu=40 I guess that shouldn't be integrated in my patch, should I ? For what I have found on websearch that should come from my gcc version ( 3.4.3 with specific stuff). But still I needed that... thanks, Maxime On Thu, Feb 28, 2008 at 7:56 AM, maxime louvel [EMAIL PROTECTED] wrote: Hi, I wanted first to check how the kernel is behaving, with a few tests.

2.6.25-rc3 on mpc8548amc doesn't boot
Hi, I am still trying to make a 2.6.25-rc3 vanilla kernel boot (an work fine in a second time) on a mpc8548amc board. I have add the platform specific stuff from the sources of the current kernel running on the cards. What I have basically add is: - arch/powerpc/platforms/85xx/mpc85xx_amc.c - arch/powerpc/boot/dts/mpc8548amc.dts I have also changed the Kconfig and Makefile in the arch/powerpc/platforms/85xx to make the kernel try to support my board I have encountered some problem when compiling a uImage that I have basically solve like this (in arch/powerpc/boot/Makefile) #$(obj)/4xx.o: BOOTCFLAGS += -mcpu=405 #$(obj)/ebony.o: BOOTCFLAGS += -mcpu=405 #$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=405 #$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=405 #$(obj)/treeboot-walnut.o: BOOTCFLAGS += -mcpu=405 I have a gcc-3.4.3 embedded compiler with some stuff specific to the platform.

Since my 2.6.23.6 image works fine, I have tried to adapt the file I have added to the 2.6.25-rc3 kernel. I have made some changes in the arch/powerpc/platforms/85xx/mpc85xx_amc.c file and in the mpc8548amc.dts file. I have attached the changes I have done on both files.

Re: 2.6.24 for mpc8458amc
Hi, yes It has something like 16550 UART. the compiler version is gcc-3.4.3 with some specific stuff for the platform. I also have a gcc-4.1.2 vanilla which has been compiled with the previous one. The 4.1.2 works if you tell it to emulate the floating point instructions. thanks Scott, without the treeboot-walnut it compiled I have still my first problem though: AMC= bootm 0x100 ## Booting image at 0100 ... Image Name: Linux-2.6.24 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size:1802038 Bytes = 1.7 MB Load Address: Entry Point: Verifying Checksum ... OK Uncompressing Kernel Image ... OK and nothing else... Any idea ? This may become from the fact that the uboot installed on the cards is old and it apparently doesn't support the newer version of the kernel image...

mpc8548amc vs mpc8548cds
Hi, first of all I am sorry if this is not the good place to ask that but I don't know where else ... My question is: Does anyone knows the difference between the mpc8548amc and mpc8548cds platforms ? I am working on an amc one but the 2.6.24 kernel is supporting only the cds one. Do you know if I can use the dts file form the mpc8548cds for the mpc8548amc ? thanks, Maxime -- Maxime Louvel 0044 7964 80 43 Allen road Whitemore reans WV60AW Wolverhampton United Kingdom ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
2.6.24 for mpc8458amc
Hi, I am trying to make a 2.6.24 vanilla kernel boot (an work fine in a second time) on a mpc8548amc board. I have add the platform specific stuff from the sources of the current kernel running on the cards. What I have basically add is: - a folder mpc8548amc, in the config/platform directory, which allow to select the mpc8548amc as the supported platform - add the following files: - arch/ppc/configs/mpc8548amc_defconfig - arch/ppc/configs/platforms/85xx/mpc_8548_amc.h and .c - I have used the dts of an another platform (mpc8548cds) which seems quite the same, but I haven't got any confirmation of that yet.

Re: 2.6.24 for mpc8458amc
Thanks for your answer, I am going to check this ppc / powerpc things. I should use the architecture powerpc, don't I? I'm not really sure I have understand what do you want to do with a BDI-2000. I access the cards through a serial line directly. cheers, Maxime On Feb 19, 2008 2:24 PM, Jon Loeliger [EMAIL PROTECTED] wrote: maxime louvel wrote: Hi, I am trying to make a 2.6.24 vanilla kernel boot (an work fine in a second time) on a mpc8548amc board.
