I created a new header file for some definitions of nand flash. That might work, but there is a compile error that i don't know how to solve it. When compiled(make) to the last "u-boot" binary file, then that can not find `__readwrite_bug'. The error message is : /usr/local/arm/2.95.3/lib/gcc-lib/arm-linux/2.95.3 -lgcc --end-group \ -Map u-boot.map -o u-boot common/libcommon.a(cmd_nand.o): In function `nand_write_page': /home/music/u-boot/u-boot-1.1.1/common/cmd_nand.c:1066: undefined reference to `__readwrite_bug' /home/music/u-boot/u-boot-1.1.1/common/cmd_nand.c:1080: undefined reference to `__readwrite_bug' make: *** [u-boot] Error 1 I think that problem comes from /asm-arm/io.h And I can not find any function about "__readwrite_bug()". so I can't slove it. My u-boot version is 1.1.1. What can I do for this error? Thanks!!
