[Resolved] Rerouting Arduino Serial data over JTAG for the nrf52

[narioinc89]

Hi Guys,

I am new to the nrf52 family of chipsets and started my work with a custom board containing the nrf52832 chip and some on board peripherals like GPS and some sensors.

I got the nordic nrf52 arduino core successfully running on the arduino IDE and was able to program a small BLE peripheral example. I was also able to get some of the on board sensors show up their value in characteristics.

But all this while, i miss a quick glance at Serial data. The code has a few Serial.begin and Serial.print calls but i am not sure how to route these internal Serial.print calls via the JTAG interface. I am using a Segger Jlink module.

My question is, is there a way to do this; i.e. getting the hardware serial data over the jtag. Do i need to do any hardware/software changes to make this happen.

Thanks

You meant SWD right? There is no jtag interface on the nRF52. I use the Segger_RTT_printf() often to send debug messages to the RTT viewer through the SWD interface.

Yes Matt correct (my bad :) confusing SWD with JTAG )

Thanks for the suggestion, ill use the same.
