CC2340R5-Q1: SWD with J-LINK

Hello,

Mingkang Song said:

1. Can the SWD interface of CC2340 be used with J-LINK programmer to program?

Yes, it should be able to be used.

Mingkang Song said:

 Is RTC enabled by default when powered on? Is initialization required? My customer said that he did not see any functions related to RTC. Where is the interrupt handler of RTC or how to set the handler? How to set the callback function of RTC interrupt?

Please see our documentation here: Timers — SimpleLink CC23xx SDK BLE5-Stack User's Guide 3.03.01.00 documentation

And

ClockP.h File Reference (ti.com)

 How to enter standby? Is it calling the interface or does the hardware enter standby by itself when there is no broadcasting? Which resources need to be closed before entering standby?

The hardware will enter standby by itself. However, to ensure that the device goes into standby, all peripherals must be turned off (i.e. UART, ADCs, etc.).

Hi Nima,

Thanks for your reply. Could you pls also answer these unmentioned questions?

2. The customer plans to implement: standby after 10s of broadcasting→ wake up only through the RTC cycle of 60s → 10s of broadcasting → enter standby again.
 Is there a demo with similar functions for reference?

Hi Nima,

We met an error during programming and we can't move on now. Could you pls help check if the program method is correct? If not please provide the correct method. Thanks for your urgent support!

1. Software settings on the PC:

Select CC2340R5 chip, select J-LINK, click start

Click start to go to the next screen

Select File:

Click load image

Then an error is reported:

2. JLINK connection method, using the SWD method of, the connection line sequence as shown below:

Hello,

What pins are the lines from the Jlink device connected to the CC2340R5-Q1?

Best,

Hi Nima,

Thanks for your reply. Addition to the question below, I also give them a LP-XDS110. It would be also helpful if you could tell me: Which pins does SWD use, and what software is used on the PC, and what are the programming steps?

Flying wire connection. 

JLINK connection method, using the SWD method, the connection line sequence as shown below:

Here are the details:

When programming the CC2340R5 chip via J-FLASH, the following error occurs:
0x0000 0000 program flash programming completed, 0x4E02 0000 CCFG flash programming failed. What is the reason for the failure of CCFG flash programming?
