Won't compile sample larger then 15 seconds at 11 mhz

[kateric]

I'm trying to compile with a sample.h file that is larger then 15 seconds at 11 mhz.
I keep getting this message when trying to compile the file for my pi pico.
I don't know cmake, or make very well. I have compile c/c++ but it's been a long time.

I get a message stating that there is not enough space in RAM but don't know where I would go to increase the reserved ram so I can just get the program compiled. I tried to increase the RAM section in the pico-pwm-audio.map file but it doesn't seem to make a difference.

Maybe I need to run cmake again after I adjust the map file? I'm not sure and just home I can get more then 15 seconds of audio to play. If this is the max amount of time, that is all I need to know.

Let me know if you need more information regarding my issue.

Thank you in advance for any assistance.

Hello @kateric ,
It's an old post but I am working on something like that for some piano with recorded samples, not successfully.
AFAIK I have to store data to flash because I havn't got enough RAM to store my samples.
I use an array buffer and timers on second core to update it at regular interval.
It's still crashing little bit but i think in a good way.

Please let me know if some of you have found a solution.
