荔枝派Zero小白（七）

2023-02-07记录使用TF卡，烧录uboot后启动kernel。

去年为了学MIPI，花了很多时间，放下了Linux，今年开始又要在这上面努力了。

之前在荔枝派Zero小白（二）_a11999114的博客-CSDN博客_weixin_37214729中烧录了uboot和kernel，也有文件系统，当时太小白了，也没注意到，在启动后，实际只是运行了uboot，实际并没有启动kernel。有一次无意间在F1C200S上发现，要运行kernel还有boot指令脚本。

这次移植时特别注意了一下，但由于参数不确定，就只是改变了文件名，没有改变mmc地址，最后在网上找到了正确的。

在F1C200s中，boot.cmd中脚本如下：

setenv bootargs console=tty0 console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 rw

load mmc 0:1 0x80C00000 suniv-f1c100s-licheepi-nano.dtb

load mmc 0:1 0x80008000 zImage

bootz 0x80008000 - 0x80C00000

在V3s中，boot.cmd中脚本如下：

setenv bootargs console=tty0 console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw

load mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero-with-800x480-lcd.dtb

load mmc 0:1 0x41000000 zImage

bootz 0x41000000 - 0x41800000

实际上，这两个地址在uboot指令中，用printenv打印信息后也有。
