I am working on a project that needs to run in low power battery backup mode if the mains fails.
I have to increment some timing variables with a 1ms base, and they need to run uninterrupted non stop.
I am using an external 32768 crystal to run the RTC.
Currently I am using an interrupt timer on ...

Thanks for that, It compiles now.

I am trying to setup ULP to run when in deep sleep.
When I compile the I_DELAY causes a compiler error.

Here is my test code:
assert(CONFIG_ULP_COPROC_RESERVE_MEM >= 260 && "this test needs ULP_COPROC_RESERVE_MEM option set in menuconfig");
memset(RTC_SLOW_MEM, 0, CONFIG_ULP_COPROC_RESERVE_MEM ...
