Add a struct variable named CAMDIVN to the clock&power structure on the s3c24x0.h under include

Refer to "Embedded Linux complete development process" P273,

(1) Add a # define Cfg_flash_cfi_driver 1 in Include/configs/sbc2410x.h

(2) Remove FLASH.O from the Board/sbc2410x/makefile

cobjs : =sbc2410x.o flash.o changed to Cobjs : =sbc2410x.o

(3) make test, error is as follows : Compile a lot of warnings, as if it is a compiler problem, here first of all, O (∩_∩) o haha ~

There are a lot of compile warnings on the top, regardless, see the error below, this error is caused by undefined ' cfg_max_flash_sect ' . Oh is asked a lot of heroes just know. Add the definition of ' cfg_max_flash_sect ' in include/configs/sbc2410x.h , temporarily defined as # define Cfg_max_flash_sect 1 seems to say that this should be based on the Flash data sheet to define, but I do not know how to define, regardless of the first. Define post-compilation:

added the definition of ' cfg_max_flash_sect ' to compile, with a good bunch of errors:

Analysis: in INCLUDE/FLASH.H:
typedef struct {
ULongSize
UShortSector_count;
ULongflash_id;
ULongStart[cfg_max_flash_sect];
UcharProtect[cfg_max_flash_sect];
#ifdef CFG_FLASH_CFI
Uchar   portwidth; < Span class= "Apple-converted-space" >    &NBSP;&NBSP;
    uchar    chipwidth;    
...
Cfi_flash.c:220:error:structure has no member named ' Portwidth ' "This error means:
There is no portwidth in the structure, from Flash_info_ The definition of T-structure can be known, and is CFG_FLASH_CFI undefined.

So, in include/configs/100ask24x0.h   plus a #define CFG_FLASH_CFI 1

(4) Add #define CFG_FLASH_CFI 1 recompile, error:
cfi_flash.c:in function ' flash_init ':
Cfi_flash.c:411:error: ' Cfg_monitor_base ' undeclared function)
Cfi_flash.c:411:error: (each undeclared identifier was reported only once

Find problem in Flash.h   and There is no definition of cfg_monitor_base in 100ask24x0.h, and the 207:ulong flash_get_size in cfi_flash.c (ulong BASE, int banknum);
    208: #if defined (cfg_env_is_in_flash) | | defined ( Cfg_env_addr_redund) | | (cfg_monitor_base  >= CFG_FLASH_ BASE)
defined in 100ask24x0.h: #define cfg_monitor_base 0x00000000 in the compilation:

(5) When compiling, there should be an error, mine is this, but others did not appear. will require defining a # define CFG_ENV_ADDR (Cfg_flash_base + 0x0f0000) This address I do not know how to define, is the definition of LV800, still do not know is right or wrong!

(6) Finally the compiler passed! Altogether added in the sbc2410x.h

#define CFG_FLASH_CFI_DRIVER 1
#define Cfg_max_flash_sect 1
#define CFG_FLASH_CFI 1
#define Cfg_monitor_base 0x00000000
#define CFG_ENV_ADDR (cfg_flash_base + 0x0f0000) These definitions.

(7) Can finally go down to the top of the board to run, although the display is still a problem

3) Memory copy cp.b Destination address to store $ ( filesize) behind the $ (filesize) is the downloaded file size, directly with $ (filesize), does not change.

4) Define debug and you can use CFI for debugging. As to what is, do not know! Never tried, just heard ...
