[参考译文] BEAGL-PLAY-SBC：将 SK-AM62 端口连接到 BeaglePlay — 不使用&#39；t boot

尊敬的 Bin：

使用 ti-processor-sdk-linux-am62xx-evm-11.01.05.03/bin 内的脚本 create-sdcard.sh 时、所有这些文件都会复制到 SD 卡中。

tiboot3-default.bin 是我在备份原始文件时创建的、并将  tiboot3-am62x-gp-evm.bin 复制到 tiboot3.bin

我现在尝试了 你的建议,但我继续得到相同的。 在 SD 卡内找不到可引导映像。

尊敬的 Daniel：

几周前、我的同事借用了我的 BeaglePlay 板。 我正在等待找回它并检查这个问题。

尊敬的 Daniel：

AM62x SDK 下载页面为 BeaglePlay 板提供了专用的 sdcard WIC 映像。 您可以使用此图像进行测试吗？

https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-PvdSyIiioq/11.01.05.03/tisdk-default-image-beagleplay-ti-11.01.05.03.rootfs.wic.xz

尊敬的 Bin：

谢谢、这款器件起作用。 但是、缺少一些用于交叉编译设置的库（例如，lib-CoAP）。

所以我需要使用   tisdk-default-image-am62xx-evm.rootfs.tar.xz as described here

TexasInstruments/ti-wisunfantund··GitHub 发布时的 TI-wisunfantund/install_AM62X_sk.md

是否可以使用该映像设置 BeaglePlay 引导？

此致、

Daniel

尊敬的 Daniel：

我认为这是可能的。 一种方法是：

-将 beagleplay 图像“tisdk-default-image-beagleplay-ti-11.01.05.03.rootfs.wic.xz"刷“刷新到 sdcard;
-将 sdcard rootfs 分区挂载到 Lunix PC 上,并重命名“/boot/"和“和/lib/modues /“其他内容以避免过度写入；
-从 sdcard rootfs 分区中删除其余的目录;
-将文件“tisdk-default-image-am62xx-evm.rootfs.tar.xz"解“解压缩到 sdcard rootfs 分区;
-重命名“/ boot/“和“/lib/modules /“至其原名；
- umount the sdcard.
