Hello
Nordic Team.
I controling nrf spi.
testing for example nrfSDK14.0.0\example\peripheral\spi\pca10040\blank\arm5_no_packs\spi_pca10040

But i have problem. difference project spi is not working.
drv_max30003.c => max30003_initchip => MAX30003_Reg_Write
Problem here ==> MAX30003_Reg_Write(SW_RST,0x000000);
but source change board is working ==>//MAX30003_Reg_Write(SW_RST,0x000000);
And i have 1 more another question. cccd_handle number difference... not solved question. plz help me.
Here my main source.
