nRF9160生產線上如何測試

[Bryan5898]

Hello, guys!

We started designing a custom board based on the nRF9160 SiP.

Is there any suggestion on where the board we designed can be used as a test point after the production line is finished?

After directly powering on, measure the voltage and current to judge whether the printed board is good or bad. Is the nRF9160 working normally?

Thanks in advance for your time and efforts.

Sincerely,

Bryan

Hi Bryan,

We have a guideline that provides suggestions for the hardware verification testing of nRF9160 at production.

Thanks!

Hi Marcus;

目前使用JTAG燒錄nRF9160-DK相同F/W到我們設計的板子上，系統顯示燒錄成功，但板子在Tx、Rx端都沒有任何反應。

你會建議從哪個方面去Debug呢?

謝謝

 Hi Marcus；

 

關於nRF9160的UART還有些問題:

我們layout好的nRF9160 EVB是透過UART1對接另一塊BT/MCU板，請問:

1. "nrf9160dk_serial_lte_modem_2023-03-02_8f26142b.hex"這個App FW是否燒錄之後就是透過"UART1"溝通Extra MCU?

2. 透過DK board練習的方式，所使用的UART2似乎跟原UART2定義不同? 該以哪組UART2為準?

附上我們的電路圖給你參考
