ISR not in IRAM!

[mandreko]

I'm trying to get esp-rfid setup on some nodemcu chips (bought here: https://amzn.to/2INQUCY) with a weigand reader (currently detached for troubleshooting). I saw that my chip is DIO instead of QIO, so I'm not sure if that's causing issues. I can upload the generic firmware from 1.0.2, and it will typically boot, but when I change the wifi settings to 'client', it no longer starts up.

I setup platformio to do a custom build, since I saw #91 (although there is no flag in platformio.ini to change any longer). I ran the 'upload and monitor' task with the 'debug' build environment. When I do that, I see my config file that I setup my wireless information in it, but it gives an interesting error message that I haven't seen anywhere else, and apparently crashes.

Here's the log:

It then just keeps cycling through reading my config file, setting up the RFID hardware, and then giving the isr and iram error message with a stack trace.

Thanks, that at least got me to where I can debug stuff.

Is there some breaking change in newer versions past 2.0.4 which cause issues?

[ver2go]

I'm not a developer but play one on the internet :). About a month ago I saw this issue and from googling, tracked it down to 6092 5995 I think https://github.com/esp8266/Arduino/releases/tag/2.5.1

I think this should fix the underlying library to run under the latest esp8266 code
monkeyboard/Wiegand-Protocol-Library-for-Arduino#38

@beikeland I tried to use your repo still got the error. Do I need to do something else?
