Hi,

i have problem with fine timer ( 20737 + SDK 2.2.1).

When timer ( for example 100 ms or any ) is started ( on new empty project ) there is only few timer interrupts and then BCM goes to some hold or locked mode.

I use puart to debug and if i put print line in timer it looks like:

Timer start

0B000000000007021F00000000@$*#04FF1EF700920103000007362A0A00640000073A2A080000000007522A5000010đţ

Timer test cycle

It is same if i use led blink, buzz, or just leave timer interrupt empty.

Thanks.

Hi,

problem was that timer_fine cannot be used without initialized timer_1s to, and after initialization of both timers everything works fine.

Go here: Sleep Deep_Sleep Explanation and Techniques and review the portion of the blog about permanantly disabling sleep.  See if this helps.
