DA14683 客製修改版的電路板

Hi,

          我們依據 DA14683 development kit Pro電路重新設計 DA14683 電路板,在更新 firmware遇到問題.

          我們使用 DA14683 development kit Pro 作為 JTAG工具,並對以下接點連線         

DA14683 development kit Pro  --> 我們的DA14683 電路板

JTAG interface

          J3-SWCLK/ADC7/P2_4 - > SW_CLK pin of custom board.

          J3-SWDIO/ADC4/P0_6 - > SWDIO pin of custom board.

UART interface

          J4-ADC0/P1_2 - > UART_TX of custom board.

          J3-P2_3 - > UART_RX of custom board.

Power in

          J4 - VBAT+ - > VBAT of the custom board.

          J4 - GND - > GND of the custom board.

          K2 - RST - > to the RST pin of the custom board. (active high)

 

使用 SmartSnippets Toolbox  版本 4.83

         當我們按 detect device 選項,軟件會出現 it's unable to detect the DA14683.

         當我們選擇  Jtag 及 DA14683-00 選項,並按開啟,訊息視窗會出現以下錯誤訊息

          [INFO    General           @20-06-22 21:36:02] Could not measure total IR len. TDO is constant high.
          [INFO    General           @20-06-22 21:36:02] Could not measure total IR len. TDO is constant high.

          [ERROR   General           @20-06-22 21:36:02] No known chip found while opening JLink connection. Terminating proccess...      

  

          我們也測試UART 輸出訊息,當我們按 detect device 選項,terminial  視窗會出現

          DA14683BB
          DA14683BB
          DA14683BB
          DA14683BB

 

          請問 DA14683 需要重置或預先燒錄bootloader嗎?

           或是有任何地方 我有遺漏的?請幫忙,感謝!

你好,

你好,

看起来是 jlink 接口还没有连接成功。

是否能先确定是硬件问题、还是软件问题?
