Selecting larger Esp32 DevKit? Sketch uses 1553523 bytes (118%) of program storage space.

Hi @js-drone,

   I haven't tried I2S, so this comment could be total rubbish, and there maybe a suitable product that will meet your immediate needs, but your question prompted me to wonder, "Does the programme really need more than 1.5 Megabytes of program storage space?"

Obviously, it is possible to write correctly coded programmes that use any arbitrarily large amount of storage, so this may not be a relevant question.

But programmes that require a large amount of storage space sometimes benefit from an analysis of the space requirements, since it is often possible to extend the available storage, albeit with corresponding limitations of how the expansion space is used for. For example, space used for storing a large selection of images as 'data' maybe 'more flexible' about the type of storage space, compared to that required to hold the executable code. 

In short, I respectfully suggest you carefully analyse your storage space 'consumers'.

I would be surprised if you actually had a large enough programme to consume 1 Megabyte for 'pure programme code' storage, but a simple data declaration like:

  int myspace[900000];

would probably be very troublesome!

I have deliberately avoided going into the details, as I presently do not know if it is relevant, but if this is unclear, perhaps, you would like to provide more specific information about your programme, etc., in the hope someone will offer a solution to your problem.

Best wishes and good luck with your project, Dave

@davee Thanks for your thoughts. From what I have tried, the library is the cause. It's rather large and trimming the program down is a task beyond my current understanding of MP3 libraries. I tried using AI, and it suggested that the program is simplified already. I am using the sample code directly from the DroneBot project, so I expect that there's a DevKit that should work off the shelf using the same code.

To clarify, this is the specific project:
ESP32 I2S Project

@js-drone

I think to get more space for your program you will need to change your partition scheme. I use the esp-idf not arduino so I don't know how to do it in the arduino ide. The 1.3Megs is a default but can be increased if needed as in your case.

@noweare ok, yes I have the Arduino IDE and the newer replacement for Atmel Studio. I am not familiar with the process, so it may be similar process. Might you time to offer a tutorial on YouTube on the partition system you know that works?

@noweare does it look like this partition tool will work to you?

You may get away with not having to create a custom partition. In the arduino ide  select tools-> partition and select "No ota" partition. This should give you 2M bytes for your program. 

You should be able to compile.

@noweare That worked great! I must have  a hardware problem because the internet radio did nothing, but the code did compile and upload as expected. Thank you!

Awesome, now the fun begins !

So on my stereo project. I used a S3 N8R8. 

I used this audio library with it for mp3 and web radio stations.

I also used a DAC and amplifier. It works wonderfully. Once the deep cold hits I plan on rebuilding it with a touch screen and remote.
