前篇您可点击上方的文章合集或文末的“上一篇 · RZ/G2L开发板使用指南（上）”查看相关文章。

首先恭喜你参考‘使用指南-上’方法，已经成功烧写flash_writer到G2L的片上RAM。接下来将介绍如何将bootloader和U-boot烧写到QSPI或EMMC，以及如何制作SD卡镜像并启动系统。

G2L开发板提供了64MB的QSPI NOR FALSH 和64GB的EMMC Memory资源，可以选择其中其一设为启动空间。

接下来从上篇这里继续我们的操作

方式1. 下载到QSPI NOR FLASH

Flash_writer 已经提供“XLS2”指令，支持把二进制文件烧写到FLASH ROM.

步骤1

烧写 bl2_bp-smarc-rzg2l_pmic.srec

串口输入‘XLS2’根据提示，输入对应地址：

('.' & CR stop load)

选择"bl2_bp-smarc-rzg2l_pmic.srec"文件，出现如下信息提供，输入’y’

SPI Data Clear(H'FF) Check : H'00000000-0000FFFF,Clear OK?(y/n)

出现以下信息，表示烧写成功

步骤2

烧写fip-smarc-rzg2l_pmic.srec

左右滑动查看更多

>XLS2 ===== Qspi writing of RZ/G2 Board Command ============= Load Program to Spiflash Writes to any of SPI address. Micron : MT25QU512 Program Top Address & Qspi Save Address ===== Please Input Program Top Address ============ Please Input : H'00000 ===== Please Input Qspi Save Address === Please Input : H'1D200 Work RAM(H'50000000-H'53FFFFFF) Clear.... please send ! ('.' & CR stop load)

选择 fip-smarc-rzg2l_pmic.srec文件，输入y

左右滑动查看更多

SPI Data Clear(H'FF) Check : H'00000000-0000FFFF,Clear OK?(y/n)

出现以下信息，表示烧写成功。

左右滑动查看更多

至此，bootloader和U-boot已成功烧写到QSPI FLASH。

方式2. 下载到EMMC MEMORY

Flash_writer 已经提供“EXT_CSD、 EM_W”指令，支持把二进制文件烧写到EMMC.

步骤1

烧写 bl2_bp-smarc-rzg2l_pmic.srec

左右滑动查看更多

>EM_SECSD Please Input EXT_CSD Index(H'00 - H'1FF) :b1 EXT_CSD[B1] = 0x00 Please Input Value(H'00 - H'FF) :2 EXT_CSD[B1] = 0x02 >EM_SECSD Please Input EXT_CSD Index(H'00 - H'1FF) :b3 EXT_CSD[B3] = 0x00 Please Input Value(H'00 - H'FF) :8 EXT_CSD[B3] = 0x08

选择 bl2_bp-smarc-rzv2l_pmic.srec

出现以下信息，表示烧写成功

至此，bootloader和U-boot已成功烧写到EMMC。长按SW9 按键关机。

制作SD文件系统

可以在windows电脑上通过工具制作，如https://rufus.ie/en/

如下选择对应的SD卡和镜像文件，开始制作，等一段时间制作完成。

最后如下安装SD卡到开发板，SW11选择QSPI引导模式

长按SW9开机，3秒事件内按下电脑任意按键，进入如下界面：
