"app_button" functions doesn't work on XL1 gpio "P0.00"

[Hugo]

Hello,

On my custom board, on nrf52832, I can can use app_buttons for all usual pins, but not the XL1 (P0.00). I didn't try XL2 (not routed)

Using this pin as input or output works fine with standard functions.  I use sdk15.2, with softdevice s132, and didnt't try without it (I'm not sure it would help, and anyway I need the softdevice)

As I'm not using the 32kHz crystal, I set my sdk_config with:

#define NRFX_CLOCK_CONFIG_LF_SRC 0
#define CLOCK_CONFIG_LF_SRC 0

#define NRF_SDH_CLOCK_LF_SRC 0

Do you have some idea?

I guess is might need some interuption configuration.

Please try attached example and see if it works on your board. It works on the DK if you cut SB1.

Thank you.
Actually, I got the bug: it's from the "..." after the init.
On several driver, asking me a pin that do not exist, I wrote "NULL" instead of the pin name. Null was unfortunately  pin P0.00.
Sorry, I guess it was obvious, I was sure it had something to do with the clock setting.now it works perfect! thanks for your help!

I have the same issue on 52832,without 32.768k,config with this:

#define NRFX_CLOCK_CONFIG_LF_SRC 0
#define CLOCK_CONFIG_LF_SRC 0

#define NRF_SDH_CLOCK_LF_SRC 0

P0.01 works well,driving a LED,

P0.00 connected to LED too,but is not undercontrl.

My problem was basically:
-I init the P0 fine
-I accidentally init again P0, though something like:

    app_uart_comm_params_t const comm_params =
    {
        .rx_pin_no    = NULL, //don't write NULL here but -1
        .tx_pin_no    = TX_PIN_NUMBER,
        .rts_pin_no   = RTS_PIN_NUMBER,
        .cts_pin_no   = CTS_PIN_NUMBER,

NULL was a very bad idea and "-1" worked much better. I hope this helps!

Thank you ,I do not use uart  and I only use P0.00 to drive LED, I am sure that I didn`t  init "NULL" in my gpio`s initlization.

this bug confused me for days。
