I have some basic project code with setup() and loop(), nothing complicated. Verification and upload works to nano 33 iot on win11, but debugging crashes to "Error: unable to find CMSIS-DAP device". Bare new install with device+lsm6ds3+mouse installs. Mouse device is disabled for usb port usage i…

[image] tpalomaki: adding delay(3000); into the setup() waits enough time to get the Serial.println("debug string") working inside setup(). With Nano I think you could try and see if adding this will do the job: ... void setup() { Serial.begin(115200); // or whatever... while(!Serial) ; …

Do you have a CMSIS-DAP device connected to the board and, if so, how ?

i dont know what that is, I just want to debug the bare arduino nano 33 iot device code. default "start debugging" button in the arduino ide default install. I'm on AMD 5000 cpu platform on win11 if it makes any difference.

If you don't know what it is then you don't have one It is an external piece of hardware that the board needs in order to use debugging in the IDE

so you mean you cant debug the arduino device by default. gotcha. why do you have the "start debugging" on the ide if the devices dont support that by default? arduino nano 33 iot is relative recent modern arduino board, that does not support debug?

Hi @tpalomaki [image] tpalomaki: why do you have the "start debugging" on the ide if the devices dont support that by default? Because some people own debug probes and would like to use the debugger. [image] tpalomaki: arduino nano 33 iot is relative recent modern arduino board, that do…

ok. I would assume the debug functionality is basically already present in the chip without major modifications. another option is to use an emulator to simulate the arduino device. also there should not be any issue to push multiple usb devices through the usb interface, to have the debug run in th…

[image] tpalomaki: another question is that why does the whole computer need to be restarted (not only arduino ide and/or the arduino device restarted) when the arduino device crashes for random reasons. I don't know about that. In over a decade of working with Arduino daily, very often inten…
