linux4.1.15内核编译
采用飞凌提供的4.1.15源码无修改，直接编译，然后将arch/arm/下的zImage文件和arch/arm/boot/dts下的imx6ul-14x14-evk-gpmi-c-256m-xx-xx.dtb文件（共8个）拷贝到mfgtools\Profiles\Linux\OS Firmware\files中对应位置，然后OTG烧写，烧写完成后启动失败VFS: Cannot open root device "mtdblock5" or unknown-block(31,5): error -19
Please append a correct "root=" boot option; here are the available partitions:

请问使用linux源码需要修改什么吗
应该是mfgtools\Profiles\Linux\OS Firmware\files\linux路径下，您的路径有问题 路径没有错，因为设备树文件和编译出来的zImage不在一个目录所以没有分别列出，不然烧写也不会成功对吧，关键式烧写完成后断电从NAND启动时，就出问题了。我想请问一下你们资料包中给出的源码压缩包解压后能否直接编译，或者需要修改文件才能使用，没有任何手册有描述 源码解压后能直接编译，详细过程可查看OKMX6UL-C_Qt5.6+linux4.1.15软件手册 第四章
