SPI POWER?

[Lionel Sacks]

Hi, I'm trying to get a SPI based peripheral going without much luck. One thing I noticed, in the debugger, is that on my implementation the field spi_base_address->POWER has the value Ø, where as in the example nRF6310 dev loop-back example (which, of course, works), it's 1. Is it possible that this is anything?

thanks for any thoughts.

Hi Stefan,

I am on nRF51 SDK v. 5.2.0 - I haven't updated all the releases this summer yet. I took the SPI examples to model a configuration etc. which was all working fine on my nRF6310 with a PCA10004 Rev. 2.20. In this setup POWER=1

I am not sure which version is on the prototype... I'll try to find out. For what it's worth, on this device: GPIO pins work for other purposes, BLE works etc.

I will look with a scope, tomorrow; but this POWER thing is the only anomaly I can find from the software side. Is the SPI sensing, somehow, that the Slave device has a reference voltage or something? If so, knowing how might help debug...

thanks.
