求助: 我现在正在学UBOOT,可是编译是总是出现start.S:313 undifined reference to “nand_read_ll”,可是我在board/ta2410/中添加nand_read.c文件,而且也在makefile中添加了nand_read.o,我找不出原因,请求您的帮助~!

楼主, 我按你的方法一步一步设置的,我把U-boot.bin文件烧写到开发板后,启动信息如下: U-Boot 1.2.0 (Jan 7 2009 - 16:55:04) U-Boot code: 33F80000 -> 33F9D850 BSS: -> 33FA35F4 DRAM: 64 MB Flash: 1 MB NAND: NAND flash probing at 0x4E000000 0 MB nand_read_ecc: Attempt read beyond end of device 20000 10000 0 *** Warning - bad CRC or NAND, using default environment In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast

你贴出的修改后程序~ #define NAND_MAX_CHIPS 1 /* Nand Flash命令层底层接口函数 */ #define WRITE_NAND_COMMAND(d, adr) {rNFCMD = d;}//此行为黑色,但是和我所贴出的程序格式不相吻合,指点一下~ /*********以下是红色***********/ #define WRITE_NAND_ADDRESS(d, adr) {rNFADDR = d;} #define WRITE_NAND(d, adr) {rNFDATA = d;} #define READ_NAND(adr) (rNFDATA) #define NAND_WAIT_READY(nand) {while(!(rNFSTAT&(1<<0)));} #define NAND_DISABLE_CE(nand) {rNFCONT |= (1<<1);} #define NAND_ENABLE_CE(nand) {rNFCONT &= ~(1<<1);} //****************以上是
