1. embOS version:

embOS for ARM version 3.88 with Atollic True Studio 4.3.1 (embOS_CortexM_Atollic_Obj_V388c).


2.CPU and eval board:

EFM32LG990F256 on stk3600


3. Start project:
Start_LEDBlink.c


We need to run low as possible power, so need EM2.

Therefore want to run OS_Tick interrupt from the RTC at variable amount but say every 1/256th second.

Despite our best efforts, we cant get the RTC hook in.

Code works okay when running from the standard timer configuration.

Has anyone any ideas as to using a RTC with wakeup as above?

Many thanks.

Rowan and Susan.
