Hello, i'm using ELDK 5, and trying to build the kernel 3.x-DENX for the amcc yosemite board. In past when i tried to build the 2.6.26.8 kernel using the ppc arch i used the following command: $ make ARCH=ppc CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux/powerpc-linux- make yosemite_defconfig $ make ARCH=ppc CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux/powerpc-linux- make uImage I've completely built the kernel and successfully run it on the board. So, since the 2.6.27 kennel yosemite for ppc arch isn't supported, and I tried build the kernel with powerpc arch. I made the following: $ make ARCH=ppc CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux/powerpc-linux- make 44x/sam440ep_defconfig $ make ARCH=ppc CROSS_COMPILE=/opt/eldk-5.0/powerpc/sysroots/i686-oesdk-linux/usr/bin/powerpc-linux/powerpc-linux- make menuconfig Here I selected yosemite board at the platform support option, and enabled the early debug UART physical address minor part 0xef600300: and major: 0x8 (as it was specified in the yosemite.dts) at the kernel hacking option, the I compiled the kernel, loaded it in the yosemite board, and got the following log: CPU clock-frequency <- 0x1fca0550 (533MHz) CPU timebase-frequency <- 0x1fca0550 (533MHz) /plb: clock-frequency <- 7f28154 (133MHz) /plb/opb: clock-frequency <- 3f940aa (67MHz) /plb/opb/ebc: clock-frequency <- 3f940aa (67MHz) /plb/opb/serial@ef600300: clock-frequency <- a8c000 (11MHz) /plb/opb/serial@ef600400: clock-frequency <- a8c000 (11MHz) /plb/opb/serial@ef600500: clock-frequency <- a8c000 (11MHz) /plb/opb/serial@ef600600: clock-frequency <- a8c000 (11MHz) Memory <- <0x0 0x0 0xffff000> (255MB) ethernet0: local-mac-address <- 00:10:ec:00:90:10 ethernet1: local-mac-address <- 00:10:ec:80:90:12
zImage starting: loaded at 0x00400000 (sp: 0x0fe2fb60) Allocating 0x419198 bytes for kernel ... gunzipping (0x00000000 <- 0x0040e000:0x007236e4)...done 0x305060 bytes Linux/PowerPC load: root=/dev/nfs rw nfsroot=192.168.57.2:/opt/eldk-5.0/powerpc/powerpcrfs ip=192.168.124.112::192.168.124.1::eolophua:eth0:off console=ttyS0,115200 Finalizing device tree... flat tree at 0x730160 It is all. No loading is forward anyway. So, my quiestions are following: * How to enable the debgu after the kernel went to "kenry" function? * What problem may stop loading the kernel?
