spi-loopback control

[Sadasivam]

Sir,

I am working in nRF52832 board with pca10036. I want to know whether the board supports a loopback control in SPI mode. I need to try for transmitting and receiving the same data through spi lines.

Thank you,

Is SPI master example could run in a loopback manner without connecting spi slave device

And I have worked the spi master example and if i set a breakpoint then keil breaks and said "The debugger has set two breakpoints at the same address".
