Allow generic configuration of the MTD partition tables via the kernel command line. Multiple flash resources are supported for hardware where different kinds of flash memory are available. You will still need the parsing functions to be called by the driver for your particular device. It won't ...
我们正常启动流程，默认是直接跳过Uboot命令行模式的，因为Uboot主要的作用是引导Kernel，一般我们不进行u...

至此start_kernel()结束,基本的核心环境已经建立起来了。 } 9)第一个内核线程 - kernel_init 三、start_kernel函数流程: asmlinkage void __init start_kernel(void) { char * command_line; extern const struct kernel_param __start___param[], __stop___param[]; ...
1、uboot引导kernel: u-boot中有个bootm命令,它可以引导内存中的应用程序映像(Kernel),bootm命令对应 common/cmd_bootm.c中的do_bootm()函数,此函数实现下面几个功能: 1)读flash中的内核映像文件 2)解压内核 3)校验内核 4)跳到内核执行(调用do_bootm_linux()函数) ...
run_command(s, 0); } 2.假设bootcmd = nandread.jffs2 0x30007FC0 kernel; bootm 0x30007FC0 <1> nandread.jffs2 0x30007FC0 kernel 从nand读出内核: 从哪里读? :kernel分区 读到哪里去?:0x30007FC0 何为分区? 简单的说就是将nand划分为几个区域,一般如下: ...
void (*theKernel)(int zero, int arch, uint params); #ifdef CONFIG_CMDLINE_TAG #ifdef CONFIG_HI3536_A7 char *commandline = getenv("slave_bootargs"); #else char *commandline = getenv("bootargs"); //(1) #endif #endif if ((flag != 0) && (flag != BOOTM_STATE_OS_GO)) ...
1、u-boot给kernel传RAM参数 ./common/cmd_bootm.c文件中(指Uboot的根目录),bootm命令对应的do_bootm函数,当分析uImage中信息发现OS是Linux时,调用./lib_arm/bootm.c文件中的do_bootm_linux函数来启动Linux kernel。 在do_bootm_linux函数中: void do_bootm_linux (cmd_tbl_t *cmdtp, int flag, int ...
on the kernel command-line to indicate the boot state. It shall use the following value: green: If in LOCKED state and the key used for verification was not by the end user. yellow: If in LOCKED state and the key used for verification was setby the end user. orange: If in the UNLO...
