Hmmm Strange why it did not take.
I re loaded the firmware via the GUI again and still works ok…
From what I have read on google other people are getting reboot loops after upgrading firmware.
see this link
I then installed on a new reflashed esp8266 and yes got same problem. boots up can go into GUI then drops out. goes into AP mode loop etc.
According to the net can be caused by corrupt modules or file system and changes is SDK versions. Hmmmm
Their advised fix is to erase flash then reload firmware. Try the below steps before this action.
I have recomiled agian the same version but did a clean on the compiler. libs are deleted and recomplied
Managed to get into old GUI after a restart. and went staight to Firmware update and did a manual load of the re compiled version.
So far all ok. no reboot cylic loops. GUI stay sound
Did a autyo upgrade from OTA Server as well seems ok.
So re down load v7.53 again from OTA and use this one.
Steps to try to fix.
Re boot device.
Wait for awhile then see if device is listed as a AP wifi. If so connect and do a device reset.
Re connect again and select you SSID and enter password, MQTT detail etc.
We just need it to connect to the network and MQTT.
Try accessing the GUI and select firmware upgrade. If you can access this then do a manual upload of the latest v7.53 (the recomiled one).
If upgrade OK and you can get back into GUI then continue device setup .
If this fails then need to do USB flash method with FTDI Adaptor. 3v or 5v ?
(Note on .FTDI Adaptor, and voltage output.)
I had the problem of header failure when writing to eprom etc and time out errors, the FTDI was only giving 3.7 volts instead of 5V. not enough juice .
I connected the 5v from power supply to pcb as normal to overcome the shortfall ONLY on the 5V input of the PCB…Not to the esp8266 directly…
