我一直在努力实现这一点，我无法让我的定制委员会工作。当我通过开发板附加我的电路板时，我收到消息“没有检测到设备。”
如果重要的话，我的定制板是.4mm厚。
C1 - C4 CL05A105MQ5NNNC
水晶 - 7m-16.000meeq-t
电感 - CV201210-2R2K.
我认为最有可能的问题领域将在C3和C4附近，曲折线。这是一款非常简单的设计，我不确定还有别的地方检查。
我尝试了最新版本的JTAG和SmartSnippets Studio推荐的版本。
谢谢，
约翰

嗨JohnCrais，
Regarding the schematic, the VDCDC and VDCDC_RF have to be connected with a min 7mm long meander line, but it seems to be connected on the PCB. Can you please make sure that the VDCDC and VDCDC_RF are connected? Also, I would strongly suggest you to follow our design recommendation for the PCB. The RF performance might be low and you should improve the grounding of the XTAL. By the way, I would highly recommend you to check the supply voltages and make sure the he 16MHz oscillator is running. Also, you mentioned that you connected your custom board with our DK, so can you please make sure that your connections are according to the “如何使用开发套件（基本或专业版）编程自定义板？“从常见问题解答页面？

谢谢，PM_DIALOG.
如何连接曲折线？我没有明确过这个。这应该是单独的电线而不是电路板上的痕迹吗？
VDCDC和VDCDC RF连接在C3和C4的焊盘之间。我不知道处理这个问题。
董事会的设计建议在哪里？
谢谢，
约翰
嗨JohnCrais，
Please find the design recommendations in the document:https：//support.dialog-seminile.com/system/files/resources/an-b-054 ...
我试图纳入在发送的链接以及文档AN-B-061中找到的设计建议。我做了几种改进，特别是在曲折线的另一侧接地和移动C4。我仍然无法实现任何事情。我插入它，SmartSnippets说没有连接设备。
我在附加的ZIP文件中添加了一些连接到DEV板的照片。
谢谢，
约翰哈里斯
嗨JohnCrais，
请检查您的定制董事会的所有电源轨道吗？请注意，应根据DA14580数据表的规格。此外，您是否能够将固件下载到系统RAM中？您的自定义板没有USB端口，是吗？
谢谢，PM_DIALOG.
我测试过，有电力进入电路板。
Right now I'm just trying to get this to work. Although this board has headers for usb, I don't have any components attached there. The only parts on the board are:
* da14580
* 2.2UH电感
* 4 - 1UF电容器
* 16MHz水晶
我没有32 kHz水晶或其他任何附加的东西。我只是在努力获得最基本的电路工作。唯一的外部连接是与DEV板的4个连接，用于电源，地，TMS和TCK。
我无法编制董事会。SMART SENIPPIETS只是说没有检测到设备。

嗨JohnCrais，
如果我能够理解正确，您正在尝试使用基本DK和智能片段通过JTAG编程您的自定义板。请您确保您的董事会与基本DK之间的连接是根据“如何使用开发套件编程定制板（基本或专业版）的连接？”从常见问题解答页面？你检查了这个链接吗？
https://support.dialog-semiconductor.com/guide/faq-dev-kits-ref-designs
另外，如果您尝试通过UART连接智能片段，请您知道吗？
谢谢，PM_DIALOG.
除了TP 2之外，我已经根据该常见问题解答了，因为我只是试图从现在开始从RAM运行一些东西。
我没有尝试过UART，我没有连接的芯片上的引脚。
嗨JohnCrais，
这是一个从Jlink软件和指示not from Smart Snippets (when connected via JTAG, Smart Snippets uses the jlink in order to access the device). I highly recommend you to check if you have configured correctly the SPI Flash pins in the Board Setup tab of SmartSnippets toolbox. Probably there is no connection between the processor on the custom PCB and the Jlink fw that tries to communicate with the device. That could be anything from connections up to problems with the PCB that make the 580 unable to operate. My suggestion is to check if the bootloader is executing in order to verify that the 580 is operating correctly. You could probe the P04 and P05 pins, and that pins should be toggled executing part of the bootloader, so when connecting to a terminal you should see the device printing garbage. Also i would suggest you to connect the board using the Jlink itself, instead using Smart Snippets and also i would try to download code via Keil.
谢谢，PM_DIALOG.
