Debuging the 'METRO M0 Express'

Post by Chendy »

Adafruit METRO M0 Express

I'm not interested in circuitPython or the drag and drop bootloader. If I re-flashed the bootloader so it was more like an 'Arduino Zero' is there any reason why I couldn't debug 'properly' as per your guide here, using both SWD and EBDG? I can only see one MCU, so fear theres no EBDG?

If not, are there any Adafruit/Arduino Arm boards - still in production - that use both SWD (via connector not solder tabs) and EDBG?

If not again, which have SWD (via connector not solder tabs)

Many thanks

I'm using a Metro M4 that way, and using a Segger J-Trace to debug code. Like the Zero, the M4 runs at 3.3V. It appears to have the same I/O pin configuration, but has a faster processor and LOTS more Flash & RAM memory to work with.

There is no EDBG on the Metro M0, only on the Arduino Zero, which has a whole extra chip to provide the debugging capability.

The Metro M0 and M4 provide SWD connectors, but you can also solder wires to the SWDIO and SWCLK pads on the bottom of any of our M0 or M4 boards, and debug that way. This SWD connector breakout will be helpful: https://www.adafruit.com/product/2743.

You can buy a J-Link debugger for $20: https://www.adafruit.com/?q=segger
