Couldn't run the scheduler after handling timer 5 Interrupt

[userHomeinit (Tarik)]

Hello richard-damon,
Thank you for your replay,

@richard-damon

My first guess is that you have not set the priority of this ISR, so its default of 0 is too ‘high’

Ok, Since my interrupt is the highest priority, why this interrupt is not executed?
Thank you in advance,
S.Tarik
