Hello all, I've been having some problem with the nodeMCU firmware. I can flash it and it works, but after some resets it stops booting and I have to reflash the firmware.

At 74800 I got something like this:

Code: Select all

ets Jan  8 2013,rst cause:1, boot mode:(3,6)

load 0x40100000, len 30452, room 16 
tail 4
chksum 0xf0
load 0x3ffe8000, len 2728, room 4

load 0x3ffe8ab0, len 13392, room 4 
tail 12
chksum 0x15
csum 0x15

Code: Select all

PORT OPEN 9600

Tested with version:

nodemcu_20150108
nodemcu_20150126
nodemcu_20150216

Anyone having same issues?

Try reflash Lua with active segment 0x7E000 to INTERNAL://BLANK.
Today, the same thing happened to me and it helped me.

I going to test more but seems to work

I have the exact same problem.
After successfully testing some examples (occasionally, the ESP restarted for some reason), I can't boot/start the ESP anymore, without reflashing.

I only tried nodemcu-flasher so far.

Edit: Flashing 0x7E000 to INTERNAL://BLANK apparently does help, at least temporarily.
