SPI sleep current issue

21 Oct 2018

Hi All

Just got an issue where after initializing SPI, my sleep current (Thread::wait) jumps from around 2ua to 400ua.

SPI spi(p23, p19, p24)

I've tried NRF_SPI0->ENABLE = 0; before my sleep but doesnt make any difference

The only way to get back to low ua sleep is to call a system_reset() and then Thread::wait

Ideas?
