Jflash的源码

## Jflash——用于烧录 VIVI (Boot loader of MIZI Research) 的工具 ##
------------------------

查看关于Jflash-s3c2410的帮助信息：

# ./Jflash-s3c2410 --help

烧写vivi到Nandflash芯片K9F1208U0M:

# ./Jflash-s3c2410 vivi /t=5

##### 使用vivi按照 bonfs文件系统对nandflash进行分区#####
##（ARMSYS2410采用了yaffs文件系统，因此不推荐此方法）##

用minicom作为控制台，与 target board进行交互.
例如分为3个区：0～192k，192k～1M，1M～

vivi> bon part 0 192k 1M
doing partition
size = 0
size = 196608
size = 1048576
check bad block
part = 0 end = 196608
part = 1 end = 1048576
part = 2 end = 33554432
part0:
        offset = 0
        size = 196608
        bad_block = 0
part1:
        offset = 196608
        size = 851968
        bad_block = 0
part2:
        offset = 1048576
        size = 32489472
        bad_block = 0

分区完成后，即可通过以下命令，进行vivi, kernel和root的烧录

vivi> load flash vivi x
vivi> load flash kernel x
vivi> load flash root x

-------------------------------------------

#######使用imagewrite进行分区######
(仅供参考，ARMSYS2410不推荐此方法）

# ./imagewrite /dev/mtd/0 -part 0 192k 1M
meminfo size = 33554432
doing partition 
size = 0
size = 196608
size = 1048576
check bad block
part = 0 end = 196608
part = 1 end = 1048576
part = 2 end = 33554432
part0:
        offset = 0
        size = 196608
        bad_block = 0
part1:
        offset = 196608
        size = 851968
        bad_block = 0
part2:
        offset = 1048576
        size = 32489472
        bad_block = 0


## imagewrite 烧录（ARMSYS2410不推荐） ##
-----------------------------------------

imagewrite

(./imagewirte <mtd_dev> <file:offset>)

- VIVI的烧录

# ./imagewrite /dev/mtd/0 vivi.bin:0

- 内核烧录

# ./imageerite /dev/mtd/0 zImage:192k

- 文件系统烧录

# ./imagewrite /dev/mtd/0 root.cramfs:1M
