提示get_mtd_device_nm未定义,但是我们在Mtdcore.c中已经定义了,所以有可能是这个Mtdcore.c没有被编译进内核。 查看 drivers/mtd/Makefile中的定义部分,需要定义CONFIG_MTD_DEVICE 宏 重新编译烧写测试 以前擦除:nand erase 60000 200000 现在擦除:nand erase kernel 发现报错了 执行help medparts 我们先执行mtdp...

2.2. 添加宏CONFIG_MTD_DEVICE 编译之后,发现报错信息如下: 在mtdparts命令的实现文件中调用了函数 get_mtd_device_nm,然而此函数没有定义,在VS Code中找到该函数定义在drivers/mtd/mtdcore.c文件中,说明此文件没有包含到工程中,继续查看mtdcore.c 文件目录中的makefile,可以看到需要定义宏CONFIG_MTD_DEVICE: 继续...
