Esp8266 don't work after uploop

1

After uploading, the new application don’t start, even after power up or reset.
In the messages i see that the code is compressed, a stub is running and then the code iss uploaded. … .?

2

What platformio.ini and code are running?

3

[env:nodemcuv2]
platform = espressif8266
lib_extra_dirs = ~/Documents/Arduino/libraries
board = nodemcuv2
framework = arduino
monitor_speed = 74880

4

So what code are you running, what are you expecting to see and what are you seeing?

5

Simple code

void setup() {
Serial.begin(74880);
Serial.println(“Starting…”);
}

No loop() function?

Also did you try another USB cable? The chip might not get enough power.

7

3.3v on the chip, tested with another nodemcu, another cable… before the platformio update, all was correct.

8

And yes there is a loop()
but empty.

9

Which version where you on previously? (from Releases · platformio/platform-espressif8266 · GitHub)

10

I don’t remember, but more to 6 month older.

11

If you replace this by

platform = espressif8266@2.0.4

it works? (You can try higher version from the link above until it doesn’t work anymore)

12

With the old version there are no mention of stub running, norcompression info.

13

The verbosity of the uploader might be lowered / different, but does the ESP run the firmware?

14

Platformio load the fimware, but the code never run. All i see are shown in my second or third post. Sorry for my poor english…

15

How can i reinstall the other version?

16

Could you find a version that works for your board from Releases · platformio/platform-espressif8266 · GitHub? (binary search / git bisect style)

17

Finaly, after 2 reinstallations, all works correctly with the last version…

18

Did you want to mention the version that worked for you, for anyone who has problems in the future? :wink:
