How to read the data in Minicom via FTDI cable?

[Aduka_27]

Hi guys,

Is it possible to read the data in Minicom if my device is not connected directly with my laptop. Instead of that, I connected my external voltage source to supply my device and use FTDI cable in order to read the data in terminal. I used this method with Arduino and it works, but here I don't know how to achieve that. I connected GND and 5V in propriety pins, as well as Tx and Rx, but I am not able to flash the device?

Every time I got this message:

west flash
-- west flash: rebuilding
ninja: no work to do.
-- west flash: using runner nrfjprog
FATAL ERROR: "nrfjprog --ids" did not find a board; is the board connected?

I use the nrf52832 board together with Zephyr!!

What HW are you trying to use the FTDI cable on? And are you using this cable to flash?

Please note that nrfjprog expects a programmer. The nRF52832 doesn't come with a preflashed serial bootloader, like most of the arduinos do.

BR,

I am using FTDI cable to flash the device and read the output in Minicom terminal, because I need to use the external voltage source for testing my app. I followed all steps related to the install setup on the official Zephyr website and I think that I have already installed all needed tools. I connected the board using 5V and GND pins to the same pins on FTDI, and I used Tx pin on my nRF52832 board (P0.06) and Rx pin on the FTDI cable. Do I need to define these pins in the code and enable UART communication in that case? I am sorry if these questions are trivial, but I am pretty now in using Nordic boards and especially Zephyr together with them. Thanks a lot in advance!!

It is not possible to flash the nRF52832 with UART unless it has a bootloader, unfortunately.
