im using Feather EVM. im using the app_ble_uart . after i added SPI to the project i dont get any errors but the code does not run (goes to main) and when i press run it goes into hard fault.
the SPI is enabled.

You mean this: https://www.adafruit.com/product/3406
Have you tried using the SPI on its own - without BLE ?
Have you used the debugger to see what's causing the Hard Fault?
Have you enabled the debug logs for information on what's causing the crash?
You mean this: https://www.adafruit.com/product/3406 - yes
Have you tried using the SPI on its own - without BLE ? - yes
Have you used the debugger to see what's causing the Hard Fault? - im using IAR debugger
Have you enabled the debug logs for information on what's causing the crash? - how do i do that ?
im using IAR debugger
So what have you discovered by using it?
Have you enabled the debug logs
When you build the 'Debug' configuration, it should enable the logs.
They may come out on the UART, or RTT
update : after testing the new SDK example of the app_ble_uart with the SPI i got it running (since nothing is connected to the Feather). after that i connected it to my board that has connection on all io's . after running the code it gets halt fault . i think it has something to do with the uart that needs IO's. i tried to disable it or change the uart tx/rx IO's to sothing else, but still no good.
this is the log :

Did you check the call-stack when debugging, to see what is running before the hardfault occurs? Do you have anything connected to the UART pins? If they are left floating, errors will be detected on the RX-line, which will result in an error code and leave the application in the error handler.
i have no need for physical uart pins, i only use it for the ble communication. i am trying to disable it with no success.call-stack is:
app_error_fault_handler()
app_error_handler_bare(uint32_t error_code = ?)
uart_event_handle(app_uart_evt_t * p_event = ?)
uart_event_handler(struct <Unnamed 41> * p_event = ?, void * p_context = ?)
uart_evt_handler(nrfx_uart_event_t const * p_event = ?, void * p_context = ?)
uarte_irq_handler(NRF_UARTE_Type * p_uarte = 0x40002000, uarte_control_block_t * p_cb = m_cb (0x20003DE0))
<Exception frame>
[nrfx_coredep_delay_us::delay_machine_code + 0]

This looks like it is caused by errors on the UART HW. Try commenting out/remove call to uart_init() in main, this is what initializes the UART peripheral. You will also have to remove calls to app_uart_put() in nus_data_handler(), as calling this when the app_uart library is not initialized will cause errors.

i did it but now in nrf_drv_uart.h , im getting :

You must have made more changes than the ones I suggested to get those errors. Did you modify sdk_config.h or remove some includes/source files?
thank you. after clearing all the errors its working.
Excellent - so please verify the answer:
