IWR6843ISK: PC connection and firmware download are not available even though MMWAVEICBOOST is replaced.

IWR6843ISK's single EVM board works well.

It's a problem.

1. After connecting IWR6843ISK and MMWAVEICBOOST (switch setting complete)
PC USB driver is connected, firmware download, IWR6843ISK related program is executed, and communication error occurs during communication.

2. I left an inquiry about the problem of MMWAVEICBOOST due to communication error 1 (see link)
MMWAVEICBOOST was judged to be defective and replaced, but the problem still persists.

I would like to know if there is a program bug in the IWR6843ISK or if a circuit improvement is needed, and what else can I try.
(If you enter the link above, screen capture of setting mode, communication failure situation, I couldn't communicate, and I tried all the measures accordingly.)

I tried all the same settings when I posted an inquiry before, and this phenomenon only occurs when connecting mmwaveicboost.
So I replaced mmwaveicboost.
Is there any other way besides that?

Can you share a screen shot of the issue, what do you mean communication error?

Also share a screen shot of your EVM set up when using the MMWAVEICBOOST.

If you can flash the device with the MMWAVEICBOOST then you should be able to run the example.

Hello Charles O

I received the mmwaveicboost that I replaced last time and am testing it.

However, the problem is not solved, so I write again..

Even if I set it correctly as in the video, the program does not download.

I am wondering if there are any settings and methods I am missing.

I will attach the setting capture photo.

Sorry to have bothered you with the same problem...

Hi,

1. Can you please confirm that the J13 jumper is not placed?
2. Confirm you are pressing reset before trying to flash
3. Does the setup with MMWAVEICBOOST work in functional mode? can you run the program you already flashed?
4. Lastly can you restart the PC, sometimes the background process of UNIFLASH hangs and prevents successful flashing.

1.J13 is open (no connection)
2. The reset button was pressed only once before attempting to connect to communication.
3. Even if MMWAVEICBOOST is set, the function does not work (same as last time).
4. It does not work on PC reboot and other PCs.
5. Replaced the last MMWAVEICBOOST, and now it is new.

Is there any way to check that UNIFLASH's background process is stopped?
Even when the firmware of mmWave_Demo_Visualizer is downloaded to the IWR6843ISK board and installed with MMWAVEICBOOST, the connection is not established.

Hi,

The issue might be with the interconnection between both boards.

If you have another IWR6843ISK, can you try that?

When I checked with the resistance test equipment after connecting the board, it was confirmed that the connection was made before the IC (check the 0 ohm short of the tester equipment). I can not check if the IC is abnormal.
There is no other IWR6843ISK..
Is there anything I need to check in circuit?

When did you get the ISK? Can you contact TI sales support to see if the IWR6843ISK is still under warranty and can be replaced?

I purchased it on 2020/11/26 at ti store with jshin@dket.co.kr account (order number: T01025855)
Can you check it?
