TLSR8258DK48D BQB Test

austinchenn

Hello,


I am attempting to perform a BQB test on the TLSR8258DK48, but cannot find the chip on the BDT. This is what the connection looks like with SWM on the Telink debugger connected to SWS pin on the board. How do I program the firmware so that I can perform tests with a CMW? Is there a manual I can follow somewhere? Are my connections correct, or do I have to use the dongle? The board does not show up in the COM port either.

Thank you for your help.

The hardware connection is as follows:
Telink Debugger           TLSR8258DK48              
    SWM                                 SWS
    3V3                                   3V3
    GND                                  GND

Select B85 and Open BQB Tool.

Configure and Download.(See Chapter 4 of the document)

The board is not showing up as a COM port. And all of the Initialize, TX, RX, and END are all grayed out. What can I do to make the COM port show up in the Device Manager?

After I "Save As" the firmware .bin file, and then try to Download and Run, this error shows up as well.

According to the phenomenon you described, the DUT programming is incorrect. For wiring, you can refer to the diagram below.


After downloading the program, click Reset to run the program. Then, connect the TX and RX pins of the DUT to the RX and TX pins of the UART device respectively, and ensure a common ground. Finally, connect the serial port device to the CMW USB interface to begin testing.

Hello, my dongle looks a bit different. What are the pins for the TX and RX and GND, and does my successful download look correct? And afterwards, does this mean the firmware has been successfully downloaded and I can plug the device into the computer for testing? Or do I connect it directly to the CMW?
