SPI is not working in custom board nrf52840

[sharmelaraju]

Hi,

I using custom nrf52840 board .I have loaded the Bluetooth program in to the custom board using swdio/swclk/vtg/gnddetect these lines.There is no problem in Bluetooth program.

When i tried the spi program into the custom board it is not working. I considered the nrf52840 custom board as master and nrf52840 DK board as slave  and tried the example SDK program 15.3 version. Here the problem the data is not transferring through spi. But when i have tried the nrf52840 custom board as slave and nrf52840 DK board as master the data is transferring between the board . I am not getting why the data is not transferring when the custom board is  made as master .

plz help me in this.

Look at what's different between your "custom board" and the nRF52840 DK.

Nobody else can help you with this, as we have no idea what your "custom board" is!

Have you tried it with two nRF52840 DKs ?

Have you used an oscilloscope or logic analyser to see what's happening on the wires ?
