BDT error

wes58

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 errom 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
