MCUXpresso IDE Exception , Probe not open while trying to debug with FRDM-KW36

123gmax — Thu, 15 Oct 2020 19:56:50 GMT

Hello,

While trying to debug application in FRDM-KW36, I am frequently getting exception as shown in below screenshot

Some time if I change the USB port then I can establish the debug session with the target but sometime it requires the reboot of the computer.

I do experience that in between debug session an error message as show below will pop-up sometime

What could be the issue? Any help to resolve this is greatly appreciated.

Note : I am interfacing KW36Z chip as SPI slave with another board (MCP2210 module as master) with below pin in FRDM-KW36. Will this cause any problem?

PTA18 -> SCLK
PTA17 -> MOSI
PTA16 -> MISO
PTA19 -> CS

Thanks,

Hi 123gmax

If you don't connect your FRDM-KW36 board to the other board, whether you have the debug issues or not? You can run the SDK code for the FRDM-KW36 directly in the MCUXpresso IDE, any debug issues, or just your own code and connect with the external boards?

What's the onboard debugger you are using now? CMSIS DAP or the JLINK?

When you connect the FRDM-KW36 to the other board, whether the two boards are using the same power supply, do you connect the GND together or not?

Please help to check the above points at first.

Wish it helps you!

If you still have questions about it, please kindly let me know!

Best Regards,

Kerry

I got the same error.

I'm using micro-usb for power supply and openSDA to debug the KW36 board

IDE mcuXpresso can probe the cmsis-dap, but show err msg as below

Unable to open probe index 1.
Error: Probe not open
