I have flashed the latest firmware v1.9.3 to my NodeMCU. After serveral days development, the webREPL doesn't boot anymore. I tried to erase flash and reprogram the firmware, but the issue still exist. Now if I rebot the board, I got
-------------------------
PYB: soft reboot
#7 ets_task(40100130, 3, 3fff837c, 4)
WebREPL is not configured, run 'import webrepl_setup'
OSError: [Errno 2] ENOENT
MicroPython v1.9.3-8-g63826ac5c on 2017-11-01; ESP module with ESP8266
Type "help()" for more information.
-------------------------
And I tried import webrepl_setup loop and follow the steps, but if I try to run webrepl, it still report error like:
>>> import webrepl_setup
WebREPL daemon auto-start status: enabled
Would you like to (E)nable or (D)isable it running on boot?
(Empty line to quit)
> E
Would you like to change WebREPL password? (y/n) y
New password (4-9 chars): mypassword
Confirm password: mypassword
No further action required
>>> import webrepl
>>> webrepl.start()
WebREPL is not configured, run 'import webrepl_setup'
Any clues? I know ENOENT stands for insufficient memory, but ESP-12F is used in NodeMCU, and I have succefully run webrepl before. So, it is not the issue. But reprogramming doesn't help either.

Re: NodeMCU WebREPL doesn't work any more
After erase board using esptool.py, before set sta_if try to configure webrepl first. I got same error if i set sta_if before configure webrepl.

Hi, Henrique,
After erasing Flash with esp tool, the boot code is:
And then I tried to entery
So, I haven't swithed ESP8266 to STA mode at that momenet yet. Now everytime I reboot the board, I got following errors:
I can reprogram the firmware, but I just wondering why reprogramming firmware cannot remove such error? And why WebREPL can boot at very first time? Is there any hidden persistance inside ESP8266 MicroPython?
After erasing Flash with esp tool, the boot code is:
Code: Select all
# This file is executed on every boot (including wake-boot from deepsleep)
#import esp
#esp.osdebug(None)
import gc
import webrepl
webrepl.start()
gc.collect()
Code: Select all
>>> import webrepl_setup
>>> webrepl.start()
Code: Select all
PYB: soft reboot
