Hi Grant, Thank you very much for your advices which were very valuable for me.
Recently I have followed your advice to move from kernel 2.6.21 to the higher one in order to have the possibility to boot the kernel from u-boot. I have copied across from you git tree the latest version of linux kernel 2.6.23 rc-2. It compiles successfully with some warnings like below: MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x223c): Section mismatch: reference to .init.text:early_init (between 'start_here' and 'initial_mmu') WARNING: vmlinux.o(.text+0x2254): Section mismatch: reference to .init.text:machine_init (between 'start_here' and 'initial_mmu') WARNING: vmlinux.o(.text+0x2258): Section mismatch: reference to .init.text:MMU_init (between 'start_here' and 'initial_mmu') WARNING: vmlinux.o(.text+0x22b2): Section mismatch: reference to .init.text:start_kernel (between 'start_here' and 'initial_mmu') WARNING: vmlinux.o(.text+0x22b6): Section mismatch: reference to .init.text:start_kernel (between 'start_here' and 'initial_mmu') LD vmlinux My observation is that the linux 2.6.23 rc-2 is not that stable as 2.6.21. In most cases It boots successfully (ie. zImage.elf) but occasionally it fails during booting. It has never occurred with 2.6.21 which I also copied from your side. For both kernels I use the same xparamerets_ml403.h file and very similar .config file Do you have some idea if it is known problem with booting in 2.6.23 rc-2? It of course could be something wrong with my ml403 board but I just wanted to get your opinion about the stability issue. Maybe it is better to use 2.6.22? Second question: In addition I wanted to ask you about u-boot tree which you have mentioned in the post on u-boot mailing list. This post was about uart lite for ml403 in u-boot. I was not able to find the project which you have mentioned there: git://git.secretlab.ca/git/u-boot.git This what interests me in particular concerning u-boot is the uart lite and temac interfaces from ml403. Thank you very much in advance for any hint Best Regards Mirek _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
