Lock program by DMA IRQ.
Now I try (DMA) Dubble memory buffers transfer to I2S peripheral By DMA ,CIRCULAR mode program.
First ,Disable DMA IRQ ,DMA is running well ,I2S stream is good,
pc.printf("DMA CR =%4x %4x \n\r" ,DMA1_Stream4->CR ,DMA1->HISR); main() loop
I can see DMA dubble buffers alternate swiching !! sine wave sound out to i2s-D/A converter..
printf out
DMA CR =42d5f 30 M0 buffer select DMA CR =42d5f 30 DMA CR =42d5f 30 DMA CR =c2d5f 30 M1 buffer select DMA CR =c2d5f 30 DMA CR =c2d5f 30 DMA CR =c2d5f 30 DMA CR =42d5f 30 M0 buffer select DMA CR =42d5f 30
But Enable DMA IRQ(Line 196),it seems program lock. STOP Printf.... main program.
Only DMA is runnig, sine wave sound out continue.
Certainly called my_irq_handler (Line 136) ,but "DMA1 HISR = 0" there is No status of DMA "in my_irq_handler(void)
What happen?
printf out
CPU SystemCoreClock is 84000000 Hz DMA1 HISR = 0 DM------stop printf
program is here

Hi, probably much too late, but I just noticed, but maybe it helps other friends.
NVIC_SetVector(DMA1_Stream4_IRQn, (uint32_t )my_irq_handler());
should be function name without ():
NVIC_SetVector(DMA1_Stream4_IRQn, (uint32_t )my_irq_handler);
