- Sat Feb 21, 2015 8:42 am #10330 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 allets Jan  8 2013,rst cause:1, boot mode:(3,6)

load 0x40100000, len 30452, room 16

csum 0x15

Tested with version:

nodemcu_20150108
nodemcu_20150126
nodemcu_20150216

Anyone having same issues?

- Sun Feb 22, 2015 1:57 pm #10433 Try reflash Lua with active segment 0x7E000 to INTERNAL://BLANK.
Today, the same thing happened to me and it helped me.

- Mon Feb 23, 2015 7:23 pm #10566 I going to test more but seems to work

- Sat Feb 28, 2015 6:57 am #10971 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.
