Calling HAL_TIM_OC_Stop_IT causes HAL_TIM_Base_Start_IT to also stop, is this normal? i want to stop a channel, not the entire base timer.
How do i achieve this? re-enabling the base timer after stopping the Channel is not working.

It's all the same for HAL_TIM_OC_Stop(), HAL_TIM_OC_Stop_IT(), HAL_TIM_OC_Stop_DMA() functions.

Hi @BSarn.1 ,
I reported this issue to our development team for deeper analysis. Meanwhile, could you please try to use the LL drivers?

i have solved for myself but i had to make a modification into the stm32f4xx_hal_tim.c
on line 1011 i have made:
/* Disable the Peripheral */ //__HAL_TIM_DISABLE(htim); //removed manually
then the base timer will continue as i desire.

Actually it's even worse - just search for all instances of "__HAL_TIM_MOE_DISABLE" in that file and all of those functions are broken the same way. Therefore the affected functions can be described as:
HAL_TIM_***_Stop***()

A dirty workaround would be to disconnect the timer signal from ita pin by changin MODE bitfield from 10b
