- Thu Jun 18, 2015 2:21 am #20786 Welcoming any ideas for decreasing iRAM usage - I'm getting dangerously close to the limit despite putting ICACHE_FLASH_ATTR on most (but not all) - really need to understand that better. But 236KB Flash limit? We just recently put a bootloader in and moved out code right down the the bottom - seems to me that there's a lot more than that amount available?

Any good ideas for reducing iRAM use further?

and file system.

Have you pushed to the limit of the 236KB irom + 32KB iram you have available? See the last section of the the esp-link project readme (and associated makefile) for info https://github.com/jeelabs/esp-link. I eyeballed my esp-link linker map and the __ arithmetic routines seem to make up ~4KB. I don't know how much work it's worth to tr and recover these. I would probably rather slice into the 16KB user settings and 4KB bootloader-mirror flash areas.
