problem when flashing the da14580

Hi my name is Kevin, I'm designing bluetooth receiver. I try to design my own moudle using Dialog which I enclose with this post.

When I try my module, the SPI Flash is working but the installed IC DA 14580 doesn't work & it coudn't be detected by Smart Snippets
Note: while I check the voltage output on the IC, the voltage is exist and it's shown 3.3 volt

can you help me to supervise my design? And Is the problem caused by the design or something else?
我要为我的整个项目使用此模块,so I do really need Dialog CS to help me overide this problem.

Kinds Regard,

Kevin

Hi Kevleo94,

Hi Kevleo94,

I am sorry, we dont offer individual reviews over the forum, you can take as a reference the designs in the reference design section and verify your schematic. Regarding your issue, Smart Snippets doesn't detect the device itself, it will detect either the JTAG or the UART port that you are connecting to the device and through those interfaces you can download code to the device. So check your connections to Smart Snippets (either UART or JTAG), and in case this is a JTAG connection you can try to check if you can connect through keil and check if Keil is able to find the device.

Thanks MT_dialog
