HamsterBear 构建可启动的镜像（更新中）

HamsterBear 构建可启动的镜像

Allwinner SoC 上电后会执行BootROM中的程序，会依次从SDIO，SPI等接口查询可引导的设备，

SPI设备具有最低引导权，若无法查询到可引导设备，会自动进入FEL模式，此时可使用sunxi-fel

通过USB启动spl或者uboot，也可以将引导文件烧写进外部flash。

提供两种启动方式

Nor Flash - XT25F128B等
eMMC/MMC TF - SDIN5D2-4G TF等

两种启动方式的配置互相冲突

从Nor Flash启动

uboot 添加 flash id

其他id的flash的添加操作类似

vim drivers/mtd/spi/spi_flash_ids.c +154

uboot 添加 CONFIG_BOOTCMD

vim u-boot/include/configs/suniv.h

添加

#define CONFIG_BOOTCOMMAND   "sf probe 0 50000000; "                           \

                             "sf read 0x80C00000 0x100000 0x4000; "  \

                             "sf read 0x80008000 0x110000 0x400000; " \

                             "bootz 0x80008000 - 0x80C00000"

uboot 修改 bootargs

# uboot中使用了一块内存作为了LCD framebuffer，如果不限制内核内存空间，会导致lcd花屏一段时间

# mem=31M 是最简单的处理办法

make menuconfig

勾选Enable boot arguments

在Boot arguments后的括号中粘贴如下内容

console=tty0 console=ttyS0,115200 panic=5 root=/dev/mtdblock3 rw rootfstype=jffs2 mem=31M

修改linux dts

修改spi0节点

&spi0 {

    pinctrl-names = "default";

    pinctrl-0 = <&spi0_pins_a>;

    status = "okay";

    spi-max-frequency = <50000000>;

    flash: xt25f128@0 {

        #address-cells = <1>;

        #size-cells = <1>;

        reg = <0>;

        spi-max-frequency = <50000000>;

        partitions {

            compatible = "fixed-partitions";

            #address-cells = <1>;

            #size-cells = <1>;

            partition@0 {

                label = "u-boot";

                reg = <0x000000 0x100000>;

                read-only;

            };

            partition@100000 {

                label = "dtb";

                reg = <0x100000 0x10000>;

                read-only;

            partition@110000 {

                label = "kernel";

                reg = <0x110000 0x400000>;

                read-only;

            };

            partition@510000 {

                label = "rootfs";

                reg = <0x510000 0xAF0000>;

            };

        };

    };
