BDT error

I was trying to Flash Zigbee firmware to 2 devices. First devicce flashed OK - as you can see from the picture below. But the second came out with and error: DUT command execute error - also can be seen on the picture. BDT version is 5.8.4

What can be the reason? Is the chip damaged?

The board is working OK now.
I don't know what fixed it.
After trying next day and pressing different buttons, trying to erase, download and finally somehow it started working again. I was able to erase and download.

You can try to erase and active before downloading

Normally, you simply click "Activate" and then "Download". The Activate function is capable of resolving a variety of problems.

I know and I have been trying it many times. I have been using Telink chips for many years now.
The only reason that I needed to to click "Activate" was because the device was programmed with "end device" firmware.
As you could see from the picture in my first post at [14:11:28] that's where I pressed "download" button.

What does this error mean - "DUT execute command error"? Could you please explain.
In one of the previous versions of BDT that I tried as well, the error description was someting about "sram ..." - I can't remeber exactly

So nobody from Telink would care to explain what this error means - "DUT execute command error"?

This issue occurs when the programmer sends a command to the DUT, but the DUT does not respond, resulting in an exception. To eliminate the impact of the firmware already running on the DUT during the download process, it is generally recommended that users click "Activate" before initiating the download.

Thank you.
Although in my case I don't know what fixed the problem, because pressing "Activate" a couple of times didn't fix it. And in the end I don't know what did.
