SDK 15.3.0 FDS example putty terminal not displaying anything

BEplane

Hello,

SDK: 15.3.0

nRF52840-DK

IDE: SES

Example: flash_fds_s140_pca10056

Example Location: nRF-SDK\examples\peripheral\flash_fds\pca10056\s140\ses

Example Documentation: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/fds_example.html

This example is suppose to have a terminal command structure to interact with the example. I am unable to get the any printouts or response to any of the commands listed.

The connection for the UART pinout is not documented for this example. I have worked out that cli_init() sets up,

#define RX_PIN_NUMBER  8
#define TX_PIN_NUMBER  6

I am using a TTL_232R-3v3 USB to Serial cable. Pinout:

Cable >> nRF52840

GND   >>  GND

VCC    >>  VDD

TX       >>   P0.08

RX      >>   P0.06

I have tried both Tx>>Tx and Rx>>Rx as well just in case, Tx>>Rx, and Rx>>Tx is usually the correct connection I checked both just in case.

I followed the putty settings page and set the putty settings for the sections labeled Terminal Settings, and UART and USB settings.

As the warning stated on the putty settings, Project settings->Debug->Debugger->RTT Enable-> Set to No. I did the same.

I connect with putty, and then run the project with the debugger. I see nothing in the Putty terminal, or the SES output, or debug terminal. additionally trying to execute the print command does not work. when pausing with the debugger the program is at sev.

    Hello,

    The Jlink programmer on the DK as a built-in serial bridge which is connected to P0.08 and P0.06 by default. So you shouldn't have to connect an external bridge to run this example. Does a "Jlink" com port appear in the device manager when you connect the board?

    You should probably change the pin assignment for TX and RX if you want to use your bridge. P0.26 and P.27 for instance. These are not connected to anything else on the board.

    It would be very helpful if this information was in the infocenter example instructions. For this example and any example that use this feature. How else would I know this feature was used for this example?

    I was able to get the serial cable to work, I believe it was a spotty connector that I replaced with a better one. But If I knew there was no need for an external serial cable I would have saved a lot of time.

    Please update the documentation to include this information and make it more comprehensive of an example.
