Dear Dialog support team!
Now, we are considering using PLT.
According to the user manual,"UM-B-041:User Manual DA1458x/68x Production Line Tool HW and GUI",Table3@page18,
it states that it can be used without connecting the RST pin.
"The reset signal must be connected if battery powered devices are used."
If the target device is NOT battery powered devices, can we understand that there is no restriction by not using the RST pin?
When I use UART connecting using ToolBox Booter, for example,
it is guided to use RST button as below.
procedure...
[ACTION Booter @17-12-21 12:52:38] Please press the hardware reset button on the board to start the download process.
[INFO Booter @17-12-21 12:52:41] Reset detected
Therefore, I was worried that the RST button should be used even if the target device does is NOT battery powered devices.

Hi Jun-ichi Tobe,
The reason that the document mentions the above is because the PLT controls the VBAT in order to reset the board (when a reset is needded), if the devices attached on the PLT are being powered by a battery in order to reset the DUT the PLT will have to access the reset itself since it wont be able to contol the VBAT line (since the DUT is battery powered). In case that the DUT is supplied by the PLT itself then you wont need the RESET line since the PLT will be able to control the VBAT line. Those are PLT configurations described in paragraph 6.10.
