导读：我不知道友善linux2.6.32的内核是否支持了mini2440的norflash，我在这里还是亲自的把mini2440的norflash支持上。移植过程分享如下： 一.添加配置项 1、修改 drivers/mtd/maps/Kconfig文件,在config_EDB7312配置项下添加如下内容: config MTD_MINI2440 tristat

我不知道友善linux2.6.32的内核是否支持了mini2440的norflash，我在这里还是亲自的把mini2440的norflash支持上。移植过程分享如下： 一.添加配置项 1、修改 drivers/mtd/maps/Kconfig文件,在config_EDB7312配置项下添加如下内容: config MTD_MINI2440 tristate "CFI Flash device mapped onMINI2440" depends on ARM && MTD_CFI help This enables access to the CFI Flash on the CogentMINI2440 board. If you have such a board, say 'Y' here. 2、修改 drivers/mtd/maps/Makefile文件,在obj-$(CONFIG_MTD_EDB7312)+= edb7312.o下添加如下内容: obj-$(CONFIG_MTD_MINI2440)+= mini2440.o 3、复制驱动文件mini2440.c到drivers/mtd/maps目录下 二.配置编译内核 # make menuconfig 以下内容必选: Memory Technology Devices(MTD)--> <*>Memory Technology Device (MTD) support [*]MTD partitioning support <*>Direct char device access to MTD devices <*>Caching block device access to MTD devices RAM/ROM/Flash chip drivers--> <*>Detect flash chips by Common Flash Interface (CFI) probe <*>Support for Inter/Sharp flash chips <*>Supportfor AMD/Fujitsu/Spansion flash chips <*>CFI flash device mapped on mini2440 下列内容(在flash上架fat16/fat32/ntfs/ext2等文件系统时才需要选上)不要选，否则会出现加载驱动模块时会出现ftl_cs:FTL header not found. DeviceDrivers -> Memory Technology Devices (MTD) -> <>FTL (Flash Translation Layer) support <> NFTL(NAND Flash Translation Layer) support <>INFTL(Inverse NAND Flash Translation Layer) support  （编辑：开发网_郴州站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
