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:

Micron : MT25QU512 Program Top Address & Qspi Save Address ===== Please Input Program Top Address ============ Please Input : H'11E00 ===== Please Input Qspi Save Address === Please Input : H'00000 Work RAM(H'50000000-H'53FFFFFF) Clear.... please send ! ('.' & 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

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
左右滑动查看更多
SAVE -FLASH....... EM_W Complete!
步骤2
烧写fip-smarc-rzg2l_pmic.srec

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:
