Hard Fault on SD functions not in main

[andi]

Hello,

i have a problem with the PCA10040. I try to set up a ANT Transmit Channel.

If "ant_channel_init" is called from main everything works fine.

But if it's called from other c file the Softdevice call "sd_ant_channel_assign" end in hardfault. Also other Softdevice calls from this C File end in HardFault. But from Main.c they work.

I've tried with a higher Stack Size which doesn't change the problem.

Any suggestions?

Greets, Andi

are you calling these functions from an interrupt handler?

Yes Thanks, Sry my fault i changed some parts of my code and didn't see it was called from SD Interrupt.

ok usual rules apply, the context you call it from has to be lower priority than the SVC call priority (I don't know what that is for ANT) else it hardfaults. So this should be pretty easy to fix !
