TIME_SYNC_TIMER_MAX_VAL ambiguity #25

Closed David140 closed 9 months ago

David140 commented 1 year ago

Hi all, I am working to merge this tool into my project.

I noticed something weird with the TIME_SYNC_TIMER_MAX_VAL parameter, probably I am missing some details. If I set TIME_SYNC_TIMER_MAX_VAL = 20000, since the main clock is 16MHz, I am expected to see a debug toggling every 1.25ms but I see a synchronous toggling with 2.5ms of period. It is the double of what should be and I can't get why.

Moreover, if I set TIME_SYNC_TIMER_MAX_VAL = 16000, the debug toggling starts correctly but then the two boards start toggling asynchronously and then crash. I made some tests and it seems that if I set TIME_SYNC_TIMER_MAX_VAL smaller than 20000 the platform can't work in stable way for long time.

Any ideas about that? Thanks, Alessio

Hi Alessio,

do you also see this behavior with the latest branch?

Thanks, Audun
