Is it really a wemos board?
Shouldn't this be just esp wroom-02?

@mcspr good question! I have got the "official" Wemos logo on it. In many places on internet I found the same board branded Wemos but also clones. But I did not find any references on the Wemos web site!

@AronHetLam Sorry but I do not understand what is the error? Can you explain please?

@rotulet, I'm not sure what exactly you are unsure about, but I'll explain the problem i had.
When I ran the script for the ESP-wroom-02 board i got an exception because there was no entry in the macros dict for flashfreq_26. Adding it, as you've done one the fix you pushed, fixed the issue for me, and i was able to generate a boards.txt with the entries needed for ESP-wroom-02.
I ran the scrip as standalone, and didn't look to deep into how it's all put together. As you can see in the issue I referenced this issue from, I had someone with a ESP-wroom-02 board that couldn't get my code compiled correctly.

Simply run the boards script and commit changes to boards.txt and documentation.

Our Check expects that we have the same filesystem contents before and after running it

(unfold the crossed out section, it shows a git-diff output of what boards.txt.py generated and what changed in the repo)

Sorry for the delay...

Thanks @mcspr for the hint!

@AronHetLam I updated the board.txt file and rebased on master.
