Hi,

Yes, while(1) is enough.

Yes I have defined m_nrf_spi_mngr using macro: NRF_SPI_MNGR_DEF.

Hi Jakub,

Did you define m_nrf_spi_mngr?

Does it look like below after add while(1)?

int main(void)
{
   APP_ERROR_CHECK(spi1_master_init());
   flash_s25fl_read_info();
   while(1);
}

Thanks

Thank you for your quick answer. It works well completely as you answers. I noticed that it doesn't work when I use spi1_master_init() and flash_s25fl_read_info() in different C source file separately. main function refers to both of the header files. It seems to cause fatal error before passing end_callback. I don't understand that...

Hi, Do you have possibility to use debugger or maybe to toggle LED during end_callback? I have compiled your source code with 2 breakpoints: one in begin_callback and one in end_callback. I can say that both callbacks were executed.

btw. in your source you are missing definition of m_nrf_spi1_mngr.

update: But at the end I was in hardfault. Let me investigate that.

update2: Ok everything is fine. Please add while(1); in main loop after your function calls.
