我是用RT1040的评估版，在下载程序的时候提示如下信息：

我该如何解决呢？我已经重新插拔评估板并且重新创建了新的工程都是提示这个错误，以下是我评估板的图片：

Thanks for answering it for me！

Hi @Zhihao1 ,

Thanks for your interest in NXP MIMXRT series!

Going into serial download mode and clearing the flash is a universal method. It works equally well for EVK and EVKB. You can refer to this post: https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/RT-board-recovery-for-debugger-connect-issues/ta...

Best regards,

Hello, unfortunately I failed in my attempt these days. The following is my error message

All of the short caps on my board are default, just toggle SW4 to: 0001。

I tried it with keil later, but I couldn't download it either

Finally, I found that my device manager has several drivers that do not have anything to do with this

Hi @Zhihao1 ,

Thanks for your information. But I need more information about what you did during the execution of the above repair process, such as which step failed, or all succeeded but still have the above problem.

Because the board repair process is mainly the following steps:

1. build a simple demo using MCUXpressoIDE to get an image running in external flash: e.g. hello_world.

2. Put the board in SDP mode, SW4: 0-0-0-1. ;

3. use a tool to flash this image into the board; (either of the tools mentioned in the post will work, MCUBootUtility is more recommended), this step is based on USB or UART;

4. reposition the board's SW4 to its original 0-0-1-0; then, retry to debug the new project in the IDE, and it should work fine;

Best regards,
Gavin
