      一、烧写问题描述:

      • 1、USB上电后设备识别

      • 2、PhoenixSuit.exe全志烧写工具识别

      • 4、烧写失败

        二、现象疑问

      • 1、USB硬件上是从CPU——共模电感——USB连接器。没有发现硬件上的问题。

      • 2、软件上使用同样的代码在双目开发板上没有问题,可以连接PhoenixSuit.exe烧录软件。

      各位大佬,需要指点迷津呀,小弟在此谢过了。

        按住FEL上电能进入烧写状态吗?

          我试一下,补充一下使用SD卡烧录系统是没有问题的。

            我记得只有安卓点这个地方才能进入烧录模式,你确认Linux可以这么做吗?

              上电后直接进去烧录界面,但是还是烧录失败。

                先连接设备后,要点一下,才能进入烧录。

                  这个问题已经困扰我们太久了,还没有什么破解办法方法吗。😂

                    我发现了一个问题,我在上电后面刚识别设备时就点击固件烧录,可以进去烧录进度条。但是发现设备管理器里面弹出有不识别的设备。这个是不是就是烧录不进去设备没有识别呀。

                    有什么办法吗?

                        和这里没有关系,我这三台电脑CPU都这样,烧录正常。

                        看下是不是电源问题,电流不够?把电源拉死了?

                          经过测试发现一个问题,使用USB供电是能识别到USB设备(Tina ADB能弹出来)。使用外部电源,把USB的电源断开就无法识别USB设备(Tina ADB不能弹出来)。
