无法在 PICO-PI-IM6UL 上闪烁 Android 事物

Question

无法在 PICO-PI-IM6UL 上刷新 Android Things，我正在使用最新的 Developer Preview 6。 ==>我遵循的步骤

1.PICO-PI图片下载 2.解压 3.clicked flash-all.bat（我用的是Win10机器）

==>输出

< waiting for any device >

==> 之后我使用 sb_loader 并尝试刷新 u-boot.imx

1. .\sb_loader_imx6ul.exe -f .\u-boot.imx

==> 输出

Found USB#VID_15A2&PID_007D#6&7DC9D1B&0&2.

在这之后我的电脑检测到新硬件，我尝试更新所以得到了这个

=> 之后我尝试闪现

PS C:\Users\Faris\Downloads\PicoPi-MXUL_NXP Pico i.MX6UL_1_userdebug_build> .\flash-all.bat

Answer 1

使用“fastboot flashing unlock”解锁引导加载程序，然后重试

Answer 2

您的问题与 UBoot 引导加载程序有关，您需要在设备上进行干净测试。

我在使用 PICO-PI IMX6UL 板时遇到了类似的问题，我在 IMX6UL 上闪烁 IMX7D 图像时出错...所以

我研究了IMX6UL的资源。

要进行干净的测试，您需要先使用 mgftools 重新刷新引导加载程序（u-boot android 兼容版本），然后才能使用 flash-all android things image 刷新您的图像。

试着按照这个一步一步来：

• 从这里下载 mfgtool：http://www.nxp.com/lgfiles/bsps/mfgtools.zip
• 如 4.1.3 所述移动板的跳线（第一张图片） https://www.nxp.com/docs/en/user-guide/PICO-IMX6UL-USG.pdf
• 遵循 9.1 中的说明，但使用此 vbs 名称 mfgtool2-brillo-mx6ul-pico-emmc-firmware.vbs https://www.nxp.com/docs/en/quick-reference-guide/PICO-iMX7D-QSG.pdf
• 等待树分钟
• 如果 DONE 100%/100% 成功。
• 恢复电路板的跳线，如 4.1.3 所述（第二张图片 在另一页） https://www.nxp.com/docs/en/user-guide/PICO-IMX6UL-USG.pdf
• 重启板子（拔下usb-c）

此时板子必须在fastboot 所以你可以使用“fastboot devices”看到它
