Blinky Example not working on nRF52840

[dbo]

Hello,

I have loaded the ble_app_blinky_pca10056_s140 example to the nRF52840DK and it works fine with the nRF Blinky mobile app.
I modified the Blinky example code to toggle Pin 7 when the user toggles the LED state in the Blinky mobile application (and this works fine on the nRF52840DK).

I have a custom board with the nRF52840 on it; when I put this code on my custom board via DFU, the GPIO does not toggle when I toggle the LED state in the nRF Blinky mobile app. Any idea what the issue may be? Do I need to modify this example code further before placing it on my custom board vs. the nRF52840DK?

Any help is appreciated, thank you
