imx6q—sabreSD自制板运行Android4.2系统,sd卡加载uboot以及系统文件,运行kernel至unpack_to_rootfs((char *)initrd_start,
            initrd_end - initrd_start)此函数时无法继续,串口打印Unpacking initramfs...       根据网上查阅以下信息配置均不能继续

These couple of kernel config variables are needed:

  • CONFIG_BLK_DEV_INITRD=y
  • CONFIG_RD_GZIP=y
See this link for an example:
     linux-imx6/arch/arm/configs/imx6_defconfig at boundary-L3.0.35_12.09.01_GA · boundarydevices/linux-imx6 · GitHub
You can also use 'menuconfig' to select it. Choose 'General Setup' on the first page:




求如何解决???
1. 有人说设置boot_args,如何设置呢,毕竟不知道地址应该是多少,size又是如何确定呢??
2. 有贴子说要编辑mfg_tools下的initramfs.cpio.gz.uboot文件,那么应该如何修改呢??

楼主你好,你u-boot起来以后,你输入print然后回车,我看一下你u-boot中的参数设置。

楼主你好,你改一下rd_loadaddr的值为0x10C00000 试一下,看能否正常烧写。

我不知道你指的是不是mfg_tools下的ucl2.xml中就是0x10C00000这个值,烧写是正常的~那是不是我该修改成0x11000000看看效果如何??

还有我试图修改uboot中的rd_loadaddr的值为0x10C00000,下载后打印printenv,log显示仍为rd_loadaddr=0x11000000

uboot版本问题吧,换成原始的版本就过了~

感谢楼主分享解决办法,请问你帖中用的uboot是哪个版本的呢?这个问题以前没有碰到过,向楼主学习一下。
