CC2650: how can I start bootLoader without using reset button?

Elin, very thank you for your replay,

and I am sorry that not replay you at time,

can you give me a tutorial on the system reset?

Try to refer to Using the ROM bootloader in Contiki-NG wiki.

thank you for your advice! I am going to try it.

hello Yikai, I have try the method you offered to me, it works well. but in that case, I still have to pressing these physical keys like reset button and user button, which is just what I want to avoid.

By the way，您的名字读起来想中文名，

so，can you speak Chinese?

Yes, I can speak Chinese.

哈哈，那太好了。我直接用中文描述我的问题吧。

我们现在想要像使用SmartRF Flash Programmer2那样，在给cc2650烧写应用程序的时候不去按下物理键，或者更准确的说是，想编写程序实现自动的烧写。这个需求有点不常用，因为按一下键又不费很多时间，主要是我们的使用场景是板子在无人值守的机房，所以要能自动更新应用程序。

您的名字是奕恺吗？

According to your description, I suppose you intend to do OTA firmware update. If that’s correct, I suppose you should use BIM (Stands for boot image manager) instead of ROM serial bootloader for booting management. By the way, 奕恺 is not my name.

thank you Chen, you are right. We originally planned to use OTA, but today our teacher said that it is better to use the serial port for programming. The link you provided provides a lot of help. Now let's see how to automatically start the boot loader without pressing the button.

Do you use LAUNCHXL-CC2650? If so, it embeds XDS110 debugger and I see no reason why it’s better to use the serial port for programming.
