Feiling OK6410 development board transplanted u-boot official latest version u-boot-2012.10.tar.bz2

Part 0 Preparatory knowledge

0.1 Key Parameters

0.1.1 Development Board Description

OK6410 is a development board released by Feiling. There are currently two versions, OK6410-A and OK6410-B. I am currently using the former. The former has also been upgraded, so there are 128M ram and newer 256 memory versions. The nand flash size is also different. The current new one is 4G. The memory size will affect the mmu part of the code in the smdk6410.c file during compilation. It will be mentioned later. You can refer to the content of the u-boot file provided by Feiling.

0.1.2 Processor Description

The development board uses Samsung's s3c6410 processor. The instruction set used by cup is: arm1176jzf-s, which belongs to armv6zk (when using gcc, it can be specified by -march=armv6zk). For more correspondence, please refer to: ARM instruction set version and ARM version;

0.2 Environment construction and data preparation

0.2.1 Development Environment Setup

System version: Ubuntu12.10

Install related compilation tools:

sudo apt-get install  build-essential gcc-arm-linux-gnueabi

Here I use the gcc-arm-linux-gnueabi series of tools contained in the Ubuntu system source. After installation, the following tools are available:

arm-linux-gnueabi-addr2line       arm-linux-gnueabi-gcc             arm-linux-gnueabi-gprof           arm-linux-gnueabi-ranlib

arm-linux-gnueabi-ar              arm-linux-gnueabi-gcc-4.7         arm-linux-gnueabi-ld              arm-linux-gnueabi-readelf

arm-linux-gnueabi-as              arm-linux-gnueabi-gcc-ar-4.7      arm-linux-gnueabi-ld.bfd          arm-linux-gnueabi-size

arm-linux-gnueabi-c++filt         arm-linux-gnueabi-gcc-nm-4.7      arm-linux-gnueabi-ld.gold         arm-linux-gnueabi-strings

arm-linux-gnueabi-cpp             arm-linux-gnueabi-gcc-ranlib-4.7  arm-linux-gnueabi-nm              arm-linux-gnueabi-strip

arm-linux-gnueabi-cpp-4.7         arm-linux-gnueabi-gcov            arm-linux-gnueabi-objcopy         

arm-linux-gnueabi-elfedit arm-linux-gnueabi-gcov-4.7 arm-linux-gnueabi-objdump

Note that when using make to compile the source code, set the CROSS_COMPILE parameter to: arm-linux-gnueabi-

make CROSS_COMPILE=arm-linux-gnueabi-

0.2.2 Related source code preparation

The relevant information provided by Feiling is in the CD, and can also be downloaded from the following website: OK6410, TE6410 development board CD download link

Focus on the original Samsung data and the uboot1.1.6 compiled by Hefei Ling:

u-boot official latest version:

wget ftp://ftp.denx.de/pub/u-boot/u-boot-2012.10.tar.bz2

Other versions can be found in this directory: ftp://ftp.denx.de/pub/u-boot

[Description:] The subsequent work mainly uses Samsung's original uboot and Feiling's organized uboot as the subject matter, and integrates them into the latest version of the official uboot; finally, it is tested on the ok6410 development board;
