We try generate signal defined by toggle table , but command do nothink. (except ARR toggles)
if (HAL_TIM_OC_Start_DMA(&htim2, TIM_CHANNEL_4, &tim_values[0], idx) != HAL_OK)
{
Error_Handler();
}
have 1.7.0 U5 firmware some known issue ? Or what is required to right setup this.
We try add enable GPDMA etc. No change. For ARR is one toggle no based on table. Seems we skip some trigger setup or U5 HAL is buggy .? Pls help. Simply we have table and require toggle for example 20 words table in time.
