Merging SPI, TWI and Buttonless dfu

[adityaj]

Hi Everyone

I am working on nrf52832 with sdk 14.0.0 on iar IDE.  TWI and SPI separately working fine in buttonless_dfu then i merged SPI and TWI in buttonless_dfu itself but due to adding both codes they stuck . .

i also try to change the priority( 2 , 3 or same) of both (TWI and SPI) and also enable the peripheral resouce sharing bit.

What IRQ level are you calling the SPI functions from? Where does the code get stuck? Is it in a "while (!spi_xfer_done)"? Or is it an APP_ERROR_CHECK() that returns?

Or does the code run fine, but it is only the transfer of data that is not working? Have you tried to analyse the MOSI pin, using a logic analyzer or an oscilloscope? 

Would it be possible to send a stripped down version of the product that can reproduce the issue?

BR,
