1.under bootloader

1)cd your_dir/mrua_EM8620L_2.5.115.RC8_dev.arm.bootirq/MRUA_src/loader



2)将flash_v3.c改名为flash.c替换原来的flash.c



3)编译





2.under linux kernel

1)cd armutils_2.5.108.0/build_arm/linux-2.4.22-em86xx/drivers/mtd



2)将mtdblock_v4.c改名为mtdblock.c替换原来的mtdblock.c



3)cd armutils_2.5.108.0/build_arm/linux-2.4.22-em86xx/drivers/mtd/chips



4)将cfi_cmdset_0002_v4.c改名为cfi_cmdset_0002.c替换原来的cfi_cmdset_0002.c



5)编译。

note:如果在使用cat等指令写flash的过程中出现下面的信息：

Flash write to Buffer aborted @ 0x****** = 0x******

是正常信息。
