Board couldn't connnect to PC and IDE

Post by Hush_2 »

Hello,

I am doing a satellite project at my university, I recently just printed EM Board with JTAG connection including (Supply, SWDIO, SWCLK, and GND) for the pinout.

After that, I am using ATSAMD12G18A for the MCU and burn it using ATMEL Studio using this tutorial here: https://learn.adafruit.com/how-to-progr ... mel-studio.

the process is successful but in my arduino IDE, the port is still not shown.

The problem is, the device is still not detected in my IDE port, and in device manager too. I wonder if the lack of RESET pin has to do with this.

For the JTAG connection, I use J-link from Segger.

could someone help me what am I missing?

As a sanity check, verify your USB cable by using it to connect some other, known-working device to the computer.

There's a plague of charge-only cables out there with USB connectors at both ends but no wires for the data signals. We see people get caught by them every day.

Just swapping cables has no diagnostic value.. the current record is someone who had to reject ten different cables before finding one that worked. You need the true positive of a working USB connection to rule out the false negative of a charge-only cable.
