#if SOC_GDMA_SUPPORTED is false but getting events from GDMA function

[noweare]

Hello.

I am using esp-idf 4.x.x.

My program is using i2s peripheral.

I am getting the "i2s_event_tx_q_ovf" event but to get that event the gdma would have to be activated.
As far as I know, that functionality is not implemented in the esp32 and the function that sends that
event is grayed out when I bring the i2s.c file into my project.

Maybe someone who has more experience with i2s can shed some light on this.

TIA

The IDF driver abstracts the GDMA support of the hardware away to provide a unified application interface across the different SoC.
See e.g. https://github.com/espressif/esp-idf/bl ... i2s.c#L467
which is in the #else branch of the #if SOC_GDMA_SUPPORTED.

That is a link to version 5. I'm using version 4.4 of the idf which does not include the code that sends the tx overflow event
to the queue.

Thanks for responding.

No, it's v4.4. Specifically, the code appears to be there since v4.4.3.

Your right.
I am using platformio, which doesn't include source of the esp-idf version that it works with.
I was looking at v 4.4.2 of the idf which I used to look at source. The esp-idf version
that platformio uses is actually 4.4.7
I did see that issue was fixed in v4.4.3 as you said.
My bad. Thanks for looking into it.
Happy programming.
