I think so. The default compile may seem to be for an 1024K flash device, but that's only because the standard 512K ld file seems to want to split the rom in two 256K segments, and that won't fit. You can try just compiling it as-is and flashing it to the addresses indicated in the README.md, I think that should work. I can't check, unfortunately, I don't have any 512K modules at hand; if you do try it, I'd love to hear if it works.

i tried and its not booting.and i tried to change ld file with original rtos sdk ld file and i am getting ".irom0.text' will not fit in region `irom0_0_seg'

Hmm. I'll try and see if I can fix this tomorrow. I was actually aiming for the barebones demo to be able to run on an ESP01, seems like it still needs some massaging.

Thank you. I've waiting a long time for i2s on esp8266 :)
