这个蚂蚁矿机的BB Black怎样能做成EHCI debug工具？ - dalao - 04-27-2020
发现咸鱼上有些蚂蚁矿机的BB Black挺便宜，买了个1.6版的，怎样能做成EHCI debug工具？
这里有人说它缺少USB外围原件，具体要再买哪些原件？ 然后又该怎样刷它？

我手上有个不知道什么版本的BBB，对比了一下。第二张图左上角那个焊盘那里应该是有个USB OTG口的，EHCI debug 用的是那个口。此外BBB有个独立的供电口，是焊在第二张图右上角C2那个位置的。
对比一下你给的帖子的那张图也能看到。
元件这东西我不是很熟，应该不难买。

这两天有点时间准备折腾下这个，看这个帖子 http://bbs.eeworld.com.cn/thread-1072298-1-1.html 说检测到sd卡就会从sd卡启动，但我这个好像检测到了但还是不从sd卡启动。
这个是矿机原系统登录网页界面的log

借这个帖子问下，是不是所有支持otg的运行linux的开发板都能做成EHCI debugger。我手上有一块廉价的i.MX280A，已经吃灰多年，当年还给他跑起来了新的uboot和4.x的内核，不知道能不能做成调试器。

再加个条件，OTG口需要EHCI支持。我觉得应该没问题。

我刚刚把我手上的BBB拿出来用了一下。我用的固件是 lynxis 做的 bbb_screwdriver (https://github.com/lynxis/bbb_screwdriver_builder). 我有一份编译好的版本在 https://wehack.space/vimacs/openwrt-0.3.0-omap-beagleboneblack-sdcard-vfat-am335x_evm.img.xz
借这个帖子问下，是不是所有支持otg的运行linux的开发板都能做成EHCI debugger。我手上有一块廉价的i.MX280A，已经吃灰多年，当年还给他跑起来了新的uboot和4.x的内核，不知道能不能做成调试器。
再加个条件，OTG口需要EHCI支持。我觉得应该没问题。
发现手上的这个hp 800 g1 dm不带usb 2.0的口，看了lshw的输出，好像也确实没接到EHCI控制器上，这种情况下是不是不能使用EHCI debug了？
