Cavium CN6300 porting 實錄

到新公司報到的第一件事情就是把這個一年前買進來的版子搞起來....但是事隔一年了...當然好多問題會發生 ..因此紀錄一下解決過程唄

Setup platform Procedure:

1. Download and compressing to /usr/local/Cavium-Networks/OCTEON-SDK

Uncompress OCTEON-SDK-2.0.0-366.i386.rpm

Uncompress OCTEON-LINUX-2.0.0-366.i386.rpm

Uncompress OCTEON-COMPONENTS-COMMON-2.0.0-58.i386.rpm

Uncompress OCTEON-PCI-BASE-2.0.0-73.i386.rpm

Uncompress OCTEON-PCI-NIC-2.0.0-73.i386.rpm

Uncompress OCTEON-ZLIB-CORE-2.0.0-31.i386.rpm

Uncompress OCTEON-ZLIB-LINUX-2.0.0-31.i386.rpm

Uncompress OCTEON-PCI-CNTQ-2.0.0-73.i386.rpm

Uncompress sdk_2.0.0_updates_p4.tgz

# cd /usr/local/Cavium-Networks/OCTEON-SDK

2. Apply the SDK patch4 and the Linux patch

# patch -s -p0 < /download/SDK_2.0.0_update/sdk.patch

# patch -s -p0 < /download/SDK_2.0.0_update/linux.patch

3. Copy bootloaders

# cp /download/SDK_2.0.0_update/u-boot-octeon_*.bin  target/bin

4. Copy oct-remote utilities

# cp /download/SDK_2.0.0_update/oct-remote-*  host/remote-utils

6. Create link to new toolchain

# rm tools

# cp /download/SDK_2.0.0_update/tools_update /usr/local/Cavium_Networks/OCTEON-SDK/

# ln -s tools_update tools

7. Add cross compiler path

#cd /etc

#gedit environment

PATH="/usr/local/Cavium_Networks/OCTEON-SDK/tools/bin:/usr/local/Cavium_Networks/OCTEON-SDK/host/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

8. Add environment

#cd /etc

#gedit bash.bashrc

pushd /usr/local/Cavium_Networks/OCTEON-SDK

source env-setup OCTEON_CN63XX

popd

9. Reboot linux

#reboot

10. We modify the Makefile

ifeq ($(ARCH),mips)
CROSS_COMPILE = mips64-octeon-linux-gnu-

11. Change the user to root and make

#sudo passwd root

#su – root

#make clobber

#make octeon_ebb6300_config

#make

It create five files

u-boot-0xffffffffbfc00000

u-boot-0xffffffffbfc40000

u-boot-0xffffffffbfc70000

u-boot-octeon_ebb6300

u-boot-octeon_ebb6300.bin

12. burning bootloader image

@Copy the image to CF card

@Plug into EVB CF socket

@Boot up EVB

@Set following command in the bootloader

Ebb6300#printenv                                 (confirm loadaddr, in my )

Ebb6300#fatload ide 0 $(loadaddr) bootloader-filename   (u-boot-octeon_ebb6300.bin)

      Or fatload ide 0x20000000 bootloader-filename    (copy image to RAM)

Ebb6300# run bootloader_flash_update                (burning image from RAM to flash)

 Or bootloaderupdate

//*********************not working ************************************

13. make kernel

#cd /usr/local/Cavium_Network/OCTEON-SDK/linux/

#make setup-octeon2

#make kernel

13. make kernel

#cp /usr/local/Cavium_Network/OCTEON-SDK/linux/kernel2.6/kernel.config ./linux

#cd linux

#mv kernel.config .config

#make menuconfig

Load .config

#make clean

#make

//*******************************************************************

   # source ./env-setup OCTEON_CN63XX

   # cd linux

   # make clean

   # make kernel strip

14. burning linux kernel

@Copy the image to CF card

@Plug into EVB CF socket

@Boot up EVB

@Set following command in the bootloader

Ebb6300#fatload ide 0 $(loadaddr) kernel-filename      (vmlinux.64)

Ebb6300#bootoctlinux $(fileaddr)                    (burning image from RAM to flash)
