Reboot Loop

[Dylantje]

Dear all,

I did something wrong with my ESP Node MCU....
I did try to upgrde the firmware from 78 to108 with the webinterface.
This option was looking ok.
Only now is the esp in a reboot loop....
Is there a way to reset or factory-settings or clean the flash, or?

Sounds similar what i had. Try to flash R108 directly with a serial connection. That works for me.

Connect your device with a usb port and use the program inside ESPEasy_R108

Fill the Comport, Flashsize en Build, that's all

Yep that is what i do...
Writing flash i see, and done @ the end...
Try this with the 78 & 108 version

Only the loop is every time there...

When you type "settings", "reset" or "reboot" you must see something,

First You must install Python27 : https://www.python.org/download/releases/2.7/
then you must install esptool.py : https://learn.adafruit.com/building-and ... h-firmware

Thanks all..
I give up..
try a other board...
Hard to get for me..

You might try flashing blank.bin. you can search for blank.bin here or google. This essentially clears out the memory so you can flash a new rom. This has worked for me.

These little guys can be really frustrating at times, but I have always been able to get them to work eventually.

i've had similar problems when I did an update from R78 to R108.
Directly after flashing the new version I removed power, connected Rx and Tx together.Reconnected power and waited a few minutes so the ESP has time to clear the data memory. Then disconnected power and removed the Rx/Tx short, reconnect power and at that moment the ESP could boot up normally and gave the AP at 192.168.1.4

Costo, you have right. Thats a way to work with R108. But for my case i work only with Stable Firmware. I started with R43 the with R77 Martinus introduced update with a bin file. So i bring my 3 devices to R77, A time later R78 came out, I updated with OTA all the 3 devices to R78, no problem at all. Now the latest release R108 i did the same trick en after that i had with all the 3 devices problems. What i have done is clear the flash with clear.ino then load R78 en then via OTA R108. But i have still problems. My 3 devices are 2x ESP-1 and 1x Sonoff. I build the ESP's in a Lamp and AXA windowopener. Now i must remove them,connect them to a pc for updating. I like the OTA feature, but not for me working.

I'm not sure if OTA feature works on 512k devices (eg. blue ESP-01)
Determine the size of the flash chip used on a module you have and then upload correct bin: 512 / 1024 / 4096. http://www.esp8266.nu/index.php/Tutoria ... Flash_size
a few weeks ago, I have uploaded (via OTA) version 4096 to 1024 device ... then there was bootloop

My ESP-01 are the black versions, and it works when i go from R77 to R78.

[Drum]

the Black version is supposed to have 1MB so you are using the "1024" version? According to the change log, OTA never worked on the ESP-01 with 512B, but if you are using the 1024 version for the ESP-01 "Black" modules it should work... I only have 2MB and 4MB modules and I have used OTA on all (about 15) of them with no problems but I don't think I ever used R108.
