Issues with NCS LOGS with Particle Xenon

[Waqas Qammar]

Hi there,

I have just started the NCS Fundamental Course and I am stuck on Exercise 4 Lesson 1 and Lesson 2. There are two problems that I am facing.

1) If I use the nrf52832DK board for build configuration. I get the logs but my button press won't be recognized.

2) If I change the board, to Particle Xenon and connect using the debug-out port. I am able to get the button press that I check using a debugger. but I am unable to see any log no matter if I use printk or LOG_INF commands. I even downloaded the solution and then flash it but it shows the same behavior.

HI Simon,

I note one thing.

I burn the ble_app_blinky program from NRF SDK just to confirm if my buttons and LEDs are fine. The LED was fine and blinking. but the button was not working. I put the breakpoint in the callback and it never hit. Then I measure the voltage at P.13 using a multimeter. It was 2.4v because of pull-up and when I press the button it goes to zero. so the button is detected voltage-wise but not in the code.

Can you try with another button, for example button 2,3 or 4?

Can you test with for example P0.30 by using the code below? Use pullup and simulate a button press by connecting P0.30 to ground.

//Use P0.30 instead
gpio_init_callback(&button_cb_data, button_pressed, BIT(30));	

Can you test the button sample <ncs>/zephyr/samples/basic/button?

Best regards,

Simon
