for nRF52840 express, What's mean "Flow control is disabled, Dual bank, Touch disabled"?

Post by kufo »

I tried "Adafruit-nrfutil, https://github.com/adafruit/Adafruit_nRF52_nrfutil"

but some errors.

+++++++++++++++++++++++++
my working environment : windows 11, PS(power shell)
PS> ./adafruit-nrfutil.exe dfu serial --package test.ino.zip -p COM5 -b 115200
PS> Upgrading target on COM5 with DFU package C:\KUFO\TEST\Adafruit\test.ino.zip. Flow control is disabled, Dual bank, Touch disabled

Failed to upgrade target. Error is: Serial port could not be opened on COM5. Reason: could not open port 'COM5': PermissionError(13,...
++++++++++++++++++++++++++++

I'm getting these errors.
What's mean "Flow control is disabled, Dual bank, Touch disabled"?

When I used the serial COM5, It's good.
like this
++++++++++++++
PS> $port= new-Object System.IO.Ports.SerialPort COM5,115200,None,8,one
PS> $port.open()
PS> $port.WriteLine(“Hello world”)
PS> $port.Close()
++++++++++++++
but when I'm using "PS> ./adafruit-nrfutil.exe dfu serial --package test.ino.zip -p COM5 -b 115200", I got error.

What's the reason of this error?
