下载CYBT-343026-EVAL失败

我正在开发一个带有CYBT-33026-EVAL的应用程序。从两天开始，就不可能在控制台上编程模块和WICE Studio打印。

遵循以下建议并重试。γ
1。验证UB-UART驱动程序是否正确安装
2。验证SW4开关处于接通位置（CTS、RTS、RXD、TXD）
3。功率循环CYBT-34 3026-EVE和重试。γ

如果这个问题仍然存在，板上的串行闪存可能会损坏。γ
跟随下面的步骤重置CYBT-34 3026-EVE板到工厂默认状态。γ
注：这将删除任何用户在内存中的应用和重置板到达弗拉特状态
1。按压恢复按钮（SW2）
2。按住复位按钮（SW1）1秒
3。释放SW1
4。释放SW2
5。重新编程板

下载失败。SDK的这个WORD平台只支持下载到20706A2设备。
10:57∶27建造完毕（取1m：27秒。577毫秒）
我已经遵守了指南和论坛帖子中的所有记录和所有的内容，但没有任何变化。尝试改变J8，但没有效果。
只有一次，我能够编程它，但再也没有。
我注意到，RTS和CTS信号（J1连接器）对于所有的通信都是AWAIS低，直到它失败为止。对吗？
司机似乎安装正确，我可以看到两个共同的“USB串行端口”，但我不确定他们是正确的，因为如果我没有错，它应该是WICE HCI UART。我已经尝试在WICE Studio路径中安装驱动程序，但是Windows没有正确安装它。我的操作系统是Windows 10。
问题何在？

  I'm developing an application with CYBT-343026-EVAL. Since two days it's impossible to program the module and the WICED Studio print in console the following message:

Downloading application...
********* Download Failure *************
+-----------------------------------------------------------------------------------------------+
| Follow below suggestions and retry. |
|   1. Verify USB-UART driver is correctly installed |
|   2. Verify SW4 switches are in ON position (CTS, RTS, RXD, TXD) |
|   3. Power cycle CYBT-343026-EVAL and retry. |
| |
| If this problem persists, the serial flash on the board may be corrupted. |
| Follow below steps to reset CYBT-343026-EVAL board to factory default state.                |
| Note: This will erase any user applicaiton in the memory and reset the board to dafulat state |
|   1. Press and hold RECOVER button (SW2) |
|   2. Press and hold RESET button (SW1) for 1 second |
|   3. Release SW1 |
|   4. Release SW2 |
|   5. Re-program the board |

10:57:27 Build Finished (took 1m:27s.577ms)

I have followed all the seggestions and all the indeications in the guides and in the forum posts but nothing change. tried also to change J8 but without effect.
Only one time I was able to program it but then never again.

I have noticed that the RTS and CTS signal (by J1 connector) are alwais low for all the comunication until it fails. Is it right?

The drivers seem installed correctly, I can see two common "USB Serial Port" but I'm not sure they are correct because, if I'm not mistaken, it should be WICED HCI UART. I have tried to install the driver inside WICED Studio path but windows do not install it correctly. My OS is Windows 10.


Where could be the problem?
