nRFgo Studio "Enable reset pin" option on nRF52 DK but not custom h/w

[hmolesworth]

nRFgo Studio displays a "Enable reset pin" option on the nRF52 DK but does not display this option on our custom hardware; we use a Segger J-Link for programming the custom hardware. The reset pin is of course set in our code, but why does this not option show in nRFgo Stdio? Maybe I am missing something on the hardware design which might be important ..

Just tested this with the nrf51 dongle & nrf go studio did not show the "enable reset pin" button either. My guess is that nrf go studio detects whether the HW has the reset button found on the dev kits. The nrf51 dongle does not have this reset button & therefore the "enable reset pin" button is missing from nrf go studio. Do you have a reset button on your custom HW?

Good suggestion, but actually the Reset button on the dev kits is a BOOT signal to the SAM3U MCU and there is no reset button connected to the nRF52 MCU, although nRESET connects to many headers non seem to have even a pull-up or capacitor to Gnd. On my design also nothing is connected; it simply routes to the 6-pin Tag-Connect header. I tried programming using the dev kit as the Segger J-Link device - which works well and is a lot cheaper than a J-Link - with the same results. I'm curious why this is so ..

If you want, you could open a new private devzone case & send us your HW reference files so we can take a look at it if you are worried you have done something wrong.
