Uploading the sketch to another board then expected

[VincentR1]

Describe the problem

The sketch is uploaded to the wrong board on dieffrent port then specifyed

To reproduce

I have 2 simulare boards
the first on port /dev/ttyACM1
the second one is on port /dev/ttyACM2

I tryed to upload my sketch to the 2. board using: arduino-cli upload -p /dev/ttyACM2 -b Infineon:arm:XMC1100_XMC2GO
It's run succesfully but the sketch gets uploaded to the 1. board, the 2. board, i targeted, is uneffected

Expected behavior

the second board should be updated

Arduino CLI version

nightly-20220920

Operating system

Linux

Operating system version

debian bullseye

Additional context

No response

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the nightly build
• My report contains all necessary details

Could you provide a copy of the verbose output of the upload (with the -v flag)?
Do you know if the same setup working as expected with Arduino IDE 1.8.x?

[VincentR1]

I tried it with the ide 1.8.19.
It updated the sensor on on the first port regardless wich port i choosed in "Tools->Ports"

In your board's platform, the serial port is not used to select the upload target (I guess they use it only for the serial monitor), you can see it because the port is not used at all in the command line:

java -jar "/home/v/.arduino15/packages/Infineon/tools/XMCFlasher/1.2.1/XMCFlasher.jar" -p "/tmp/arduino-sketch-47D7AF5586EB509566B17F69DFB282A0/HallSensor.ino.hex"  -device "XMC1100-0064"

It seems that they are using the SWD protocol to upload that "autodetect" the board to upload to. In this case, it is just uploading to the first available board.
I don't think there is much we can do from the Arduino-CLI side.

We are tracking the request for a capability to specify which board to target under these conditions here: #770

Actually, thinking about it more, this is already available for uploads (but not for burn-bootloader as requested at #770):
