Using both AWS and Dallas OneWire temp sensor causes core dump #313

Closed zendes closed 7 years ago

zendes commented 7 years ago

I have a nodemcu esp-12e that is connected to a dallas ds18b20 onewire temperature sensor reading the temperature from the sensor works as expected

commenting out that code, connecting the module to aws iot and publishing a message works as expected

when uncommenting the onewire libraries in init.js (apiarduino{onewire,dallas_temp}.js) the module crashes with an exception (logs below)

is this a known issue?

Looks like OOM. Could you log free RAM as well please?

zendes commented 7 years ago

I've gotten another interesting error message: heap integrity broken: block links don't match: 3473 -> 3604, but 3604 -> 3328

i've attached two logs with free ram (timer at 100ms, just doing print Sys.free_ram())

err1.txt err2.txt

zendes commented 7 years ago

looks like it's indeed free RAM. if i comment out all load statements besides sys, timer, onewire and dallas_temp it does succesfully connect.

looks like the initial mqtt connect takes about 11k of ram. do you have any tips on how to load libraries after that? if i add load statements later in the code, they don't seem to work (i get an error about not being able to read the file)

cpq commented 7 years ago

We need to restore mmap and JS pre-compile. @dimonomid please handle!

dimonomid commented 7 years ago

@zendes , we've restored mmap on esp platform, this frees 5+ K of RAM. Please try now with the latest firmware (if you use release, you'll need to update to latest with mos update latest)

zendes commented 7 years ago

Will do. I'll get back to you in about a day with the results.

zendes commented 7 years ago

looks like that fixed it. i can now load all libs at the top, and publish a ds18b20 reading to aws iot without the device rebooting or crashing. thnx!
