Programming the device

尊敬的PM\U Dialog，

非常感谢您的快速回放，也祝您新年快乐！

我们已将定制的电路板连接到Pro-DK，如文档所示。

Now when we are trying to program the device with Dialog Smartbond Flash Programmer for Windows OS we get the following massage:

[ERROR General @21-01-05 15:36:03] No known chip found while opening JLink connection. Terminating proccess...

所有的跳线和电线都是按照文件连接的。

We have tried to lower the clock frequency to 2MHz, 1MHz and we still receive the same error message.

我们还尝试使用SmartSnippets工具，收到了：

[INFO General @21-01-05 15:29:36] Could not measure total IR len. TDO is constant high.
[INFO General @21-01-05 15:29:37] Could not measure total IR len. TDO is constant high.
[INFO General @21-01-05 15:29:37] Could not measure total IR len. TDO is constant high.

[INFO General @21-01-05 15:29:37] Could not measure total IR len. TDO is constant high.
[ERROR General@21-01-05 15:29:37]打开JLink连接时未找到已知芯片。正在终止进程。。。
[错误OTP Image@21-01-05 15:29:37]无法将固件文件下载到主板。

What can cause this problam and how can we fix it?

顺致敬意，

In the SmartSnippets Tool we tried SPI Flash as well and not only OTP

尊敬的PM\U Dialog，

是的，我可以检测到JTAG序列号。

目前，我们已将主板中的SWDIO（J1引脚23）连接到模块中的J9（P0\ U 10/SWDIO），并将主板中的SWCLK（J1引脚21）连接到模块中的J10（P0\ U 2/SWCLK），正如文档中所述。

我们还连接了VCC（3.3V）和GND，如文件所示，因为我们没有连接外部电源。

尊敬的PM\U Dialog，

We are able to program the DA14531 Module Development Kit PRO using Dialog SmartBond Flash Programmer.

我们还尝试将定制的电路板SWDIO和SWCLK连接到J2 P15和J2 P22，因为它们似乎连接到DA14531模块开发工具包PRO SWDIO和SWCLK引脚。

We used this document to see how to connect the jumpers:http://lpccs-docs.dialog-semiconductor.com/Tutorial_SDK6/codeless.htmland we tried to pragram both devices simultaneously using Dialog SmartBond Flash Programmer.

它也没有工作，只有DA14531模块开发工具包PRO得到编程。

Hope it helps to understand the situation.

谢谢你的帮助！

尊敬的Dialog\u PM：，

What do you mean by saying attach the debugger?

We are able to debbug the program when using DA14531 Module DK Pro but not with our customed board if this is what you are asking.

I have attached screen shots from both SmartSnippent and SmartBond, two screen shots show how it works with DA14531 Module DK Pro and the other 2 show what we get with out customed board.

我们假设我们从“线路板设置”中选择了正确的SPI管脚，因为它与DA14531模块DK-Pro一起工作，但这里我们可能错了。

尊敬的Dialog\u PM：，

非常感谢您的帮助，我们都非常感谢！

We have connected it correctly and tried what you did and it worked with DA14531 Module DK Pro.

We connected the DA14531 Module DK Pro to the motherboard and disconnected SWDIO and SWCLK jumpers and connected the DA14531 Module DK Pro SWDIO and SWCLK directly as if it was a customed board (just like you did but with only one motherboard) and it worked perfectly.

We thought that the Tiny Module it self, the one we mounted on our customed board is not working properly so we decided to replace it with a new one, unfortunately it did not work either.

Are we suppose to do some kind of first Initialization to the Tiny Module before programming it?

Best regards and thanks in advance

尊敬的PM\U Dialog，

我们拿了另一个小模块，没有定制板，连接了SWDIO和SWCLK，它成功了！

我们在定制的电路板上安装了这个小模块，它也工作得很好，我们之前检查过的两个小模块可能都坏了。

Thank you very much for your kind help, we really appreciate it!

致以最诚挚的问候。

尊敬的PM\U Dialog，

The problem was fixed, both modules we tested were bad but the third worked fine.

Sorry for the trouble and thank you very much for everything.
