Hi all,
working on a project with T_4.1 here, would like to know a little more about the flash memory on this board,
I've seen some detailed information about the memory on T_4.0 product page but didn't find anything about T_4.1

I would like to know if the extra flash memory could be used for playFlashRaw,
if not, is there a (more or less easy) way to copy audio files from the microSD card to the flash memory?
I know wav2sketch but need something to do the task within the Teensy itself

thanks in advance
