Linux 2.6.20.3自定义nand flash分区表问题
Linux 2.6.20.3自定义nand flash分区表问题
由于用了新的Linux 2.6.20.3内核，在进行自定义nand flash分区时仍然按 照以前的步骤，在devs.c中自己添加分区信息，熟不知在2.6.20.3内核在common-smdk.c中已加入了nand- flash驱动，而我又在devs.c中自己定义了分区，所以出现了以下错误| Copy linux kernel from 0x00200000 to 0x30008000, size = 0x00400000 ... done zImage magic = 0x016f2818 Setup linux parameters at 0x30000100 linux command line is: "noinitrd root=31：03 init=/linuxrc console=ttySAC0" MACH_TYPE = 193 NOW, Booting Linux......
