I get new boards from the shop but they are little different from the previous version. I got software what works ok on Nodemcu lolin v3 now I get Nodemcu Amica what is almost same board but if I got attachInterrupt function in the program it crashes immediately.

    attachInterrupt(6, bowlingCall, RISING);
//attachInterrupt(digitalPinToInterrupt(D1), statekCall, RISING);

I try different pins but not change. I debug all program(comment all out and left just attachInterrupt and it crashes again).

    ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d

The board cycle in the reboot sequence, even serial output do not work ok. Why did esp crash at attachInterupt on this board?

thanks @Juraj.

Ok, so all you need is rewrite all your interrupt function. For example:

void getStatusFromMaster()


void ICACHE_RAM_ATTR getStatusFromMaster()
