Let's Control It

hello all,

normally I had never issues using esp easy. Now I bought new modules because of external antenna
D1 mini pro 16M based esp-8266ex

I flashed with this bin:
ESP_Easy_mega_20210503_normal_beta_ESP8266_16M_LittleFS.bin

But it ended up in a bootloop

Due to my unexperience I am not able to decode these lines:
I hope someone can help me solving my issue.

Big thanks for your help

--------------- CUT HERE FOR EXCEPTION DECODER ---------------

Please, any help is highly appreciated, I am very desperate.

Without the exact build configuration and sources of exactly that state of development, it isn't very possible to decode what went wrong.

Possible solutions:
- Power the unit off and on after it is flashed
- Try to re-flash the unit, sometime it just doesn't 'stick' right the first time
- Try to install a standard normal_4M1M build on the unit and see what that does (it won't hurt the hardware)

Many Thanks for your reply.

I flashed it with this one ESP_Easy_mega_20210503_normal_ESP8266_4M1M.bin
(powered off after flashing)
It seems that wifi start is causing issues?

and received this:

--------------- CUT HERE FOR EXCEPTION DECODER ---------------

You can try to flash an 'alt_wifi' build, as there seems to be something crashing there, that might be resolved by the alternate WiFi configuration. That has been reported with other units having a different WiFi hardware configuration, AFAIR.

If that doesn't work, there is also the 'beta' build, having a beta release of the Arduino base libraries, that could have different WiFi behavior.

Thanks for the additional hints.

alt wifi did not work.
I tried after that
ESP_Easy_mega_20210503_test_A_alt_wifi_ESP8266_4M1M_VCC
and
ESP_Easy_mega_20210503_test_A_beta_ESP8266_4M1M

both ended in bootloops at network position


Maybe some more ideas?

I'm 99.9999999% sure you got modules with really bad voltage regulators.
The unit seems to crash when you start the WiFi and apart from that a lot of users lately have reported issues with so called "Wemos" modules related to stability issues.

You can try adding a 22 uF capacitor to the 3V3 and GND, as close as possible to the Wemos module.

Also make sure to use the best quality USB cable you have and try to power the unit directly from an USB port on the PC, not via a hub (unless it is a powered USB hub)

Not sure what to do next, apart from leaving really bad reviews on Ali Express et.al. related to the never ending story of Chinese sellers trying to scrape off the last 0.00001 cent of costs price to get even worse voltage regulators placed on the modules, some without even the required capacitors.
It is getting worse every month so it seems.

OMG you are a genius!!!!
I tried i with an old NOKIA cable. Flashing etc no problems but the power delivered was obviously not enough!!!
All is working fine

Thank you so much ....

Ah good to know it is resolvable with another USB cable.
May restore the faith in the quality of sold "Wemos" modules a bit more, as I really noticed an increase in garbage units being sold lately.

By the way, it is still possible the cable you first used is perfectly fine, only not with that specific unit.
Some ESP boards have micro USB connectors which may be a little "wide" or have slightly shorter pins so they may not work well with all micro USB cables especially when you need slightly higher current.
