+
+## 启动 LinuxLab
+
+```bash
+cd ~/Documents/labspace/cloud-lab
+tools/docker/update linux-lab
+tools/docker/bash
+```
+
+### 进入 LinuxLab
+
+```bash
+git branch -vv
+# * master 13e7c8f [origin/master] Linux Lab v0.6-rc1
+git pull
+git checkout ebf
+```
+
+查看文档
+
+[泰晓科技/Linux Lab EmbedFire i.MX6UL/ULL-EVK-PRO Board](https://gitee.com/tinylab/linux-lab/tree/ebf/boards/arm/ebf-imx6ul)
+
+使用 mmc
+
+```bash
+sed -i -e "s/imx6ul-nand-npi.dtb/imx6ul-mmc-npi.dtb/g" boards/arm/ebf-imx6ul/Makefile
+```
+
+编译
+
+```bash
+make BOARD=arm/ebf-imx6ul
+make kernel
+```
+
+macOS 系统下 patch 有点问题，用 Ubuntu 18.04 试试。
+
+后来把把 `cloud-lab` 删除重来，又正常了，可能是我昨天改错东西了。
+

+
+```bash
+make kernel-save
+make modules-install
+
+ls boards/arm/ebf-imx6ul/bsp/kernel/v4.19.35/
+# imx6ull-nand-npi.dtb  zImage
+$ ls boards/arm/ebf-imx6ul/bsp/root/2020.02/rootfs/lib/modules/
+# 4.19.35+
+rm boards/arm/ebf-imx6ul/bsp/root/2020.02/rootfs/lib/modules/4.19.35+/{source,build}
+```
+
+## 上传 zImage & dtb
+
+我是在远程编译的，要先 `scp` 到本地，再从本地 `scp` 到 **开发板**。
+
+如果使用 *MobaXterm* 是可以直接拖放的。
+
+最好备份一下。
+
+### PC
+
+```bash
+scp boards/arm/ebf-imx6ul/bsp/kernel/v4.19.35/zImage debian@192.168.1.128:~/
+scp boards/arm/ebf-imx6ul/bsp/kernel/v4.19.35/imx6ull-mmc-npi.dtb debian@192.168.1.128:~/
+scp -r boards/arm/ebf-imx6ul/bsp/root/2020.02/rootfs/lib/modules/4.19.35+ debian@192.168.1.128:~/
+```
+
+### Board
+
+```bash
+sudo mkdir -p /boot/dtbs/4.19.35+
+sudo mv ~/imx6ull-nand-npi.dtb /boot/dtbs/4.19.35+/
+sudo mv ~/zImage /boot/vmlinuz-4.19.35+
+
+sudo mv ~/4.19.35+ /lib/modules/
+sudo update-initramfs -u -k 4.19.35+
+```
+
+### Boot 新 Image
+
+`mmc` 和 `sd` 都是用的 `imx6ull-mmc-npi.dtb`
+
+```bash
+$ sudo sed -i -e "s/uname_r=.*/uname_r=4.19.35+/g" /boot/uEnv.txt
+$ sudo sed -i -e "s/dtb=.*/dtb=imx6ull-mmc-npi.dtb/g" /boot/uEnv.txt
+$ sudo reboot
+```
+
+### BOOT 拨码开关
+
+mmc: `2-4-5-7`
+
+![macOS](/assets/images/LinuxLab/IMX6ULL/ebf.png)
+
+版本改成：`4.19.35+`，时间改成 `2020/12/26`，说明 Linux Lab 下是可以进行真板开发的。
+
+sd: `2-5-8`
+
+![sd_error](/assets/images/LinuxLab/IMX6ULL/sd_error.jpg)
+
+`dtoverlays` 的路径要改一下，下周再试吧。
+
+![sd](/assets/images/LinuxLab/IMX6ULL/sd.png)
+
+后续可以自动更新到 **开发板** 上，不需要现在这样麻烦，期待中...
