Problem of flash/start on D1 Mini Pro

[vincen]

Hi

After having used few NodeMCU V2/V3 with ESP Easy I wanted to test it on D1 Mini Pro. I just received mine and I have a little issue. I did a clean of the flash without problem:

Code: Select all

vincen@Fixe-Ubuntu:~/Bureau$ esptool.py --port /dev/ttyUSB0 erase_flash

Then I flashed the firmware in it also without any troubles:

Code: Select all

Once rebooted I get blue led on board to blink once every 3/4 seconds and that's it ! I have no ESP_0 wifi signal appears !
What can I do to find the problem ? and fix it ?

Thanks

Try to connect with a serial adapter and see what is going on. I had a similiar thing, when connecting with serial I saw numbers running up. After it finished running up, it booted normally and I found the ESP_0.

Well I connected with Minicom to the USB port of the D1 and it's stuck in a boot loop Here is what I get in bootloop ? I'm going to try the other versions avalaible to check if it's the same !

D1 Mini PRO has 16Mb and not 4Mb si I suspect the issue is that you need to compile the firmware with the right settings and not to use a precompiled one...

EDIT: why your are flashing an ESP8266 with ESP8285 compiled??

oki my fault, I expected smaller firmware to fit in larger chips no ?

EDIT: why your are flashing an ESP8266 with ESP8285 compiled??

I used the precompiled one avalaible on website so going to look now for version for 16M and try to flash it and see how it goes

Update: I installed PlatformIO in my Atom and downloaded source to build a custom one but there is no option to set memory higher than 4Mb and I found none precompiled for 16M

Your assumption that smaller firmware should fit is correct. I use precomiled *.bin on D1 pro mini, I think the 8285 vs 8266 is the relevant problem here.

ESP8285 has 1MB built-in flash memery using DOUT flash mode. Your WEMOS has got external flash memory (either 4 MB or 16 MB, of which only 4 MB can be really used) which needs to be flashed in DIO mode. Size of the precompiled program doesn't matter as reported already.

I had the same problem, and ended up installing the arduino compiler, and built ESP Easy from source.
There are a lot of tutorials online that describe some changes you need to make for the ESP, mostly adding 4 libraries.

Using the code I built, I was able to get a pro to run, and ESP_0 shows up after a few minutes.
