Is "platform = espressif32@5.2.0" strictly needed? Will it also work with platform = espressif32@5.1.1 ?
I'm asking because espressif32@5.1.1 has been tested also with other new boards, and there is currently more confidence in the 5.1.1.

It is mentioned for another C3 board here #1940 (comment) as a prerequisite for a successful boot...

Can you still try if platform = espressif32@5.1.1 works with your board?
I would like to exclude 5.2.0 for the moment, unless it is strictly proven to be necessary.
We have reports from several people (including @blazoncek) who seem to be successful with 5.1.1 also for -C3.

Yes, that is true. C3 is working for me with 5.1.1 using build environment present in WLED.

Am i correct that the "flash_size" and "name" lines are the only difference to esp32-c3-devkitm-1 ?
If yes, then maybe lets make the whole thing more generic, and rename the board def to something like esp32-c3-devkitm_2M.json ? @blazoncek what do you think?

Flash size may be different on many boards and add to that that some may feature PSRAM as well.
It will be inevitable to add as many build environments as there are possible boards or provide instructions how users can create their own environment in PIO override.

I think the 2M partition table may be usefull for others too, because currently we don't have a WLED partions.csv for mcu's with 2M flash only. @andyshinn is OTA still possible with 2M?

Not for C3, S2, S3 or regular ESP32

just a small file renaming here - to be more consistent with other partition tables -
please name this file WLED_ESP32-C3_2MB.csv

useful for small -C3 boards with 2MB flash memory only. Based on suggestions from wled#2951 . Needs `-D WLED_DISABLE_OTA` as OTA is not possible with 2MB. RAM: [== ] 22.5% (used 73724 bytes from 327680 bytes) Flash: [========= ] 94.9% (used 1492020 bytes from 1572864 bytes)

What is the status of this PR? Requested changes are pending since 2022? |

A newer more thorough and generic PR is open for 8266, C3, S2 & S3. #3144 |
based on proposal from in PR #2951 by @andyshinn. 2MB does not allow to have an OTA partition, so this feature is disabled.
An addition to support the Ai-Thinker ESP32-C3-12F module which has 2MB flash and needs a special board and partition layout. Board is not officially supported upstream yet (platformio/platform-espressif32#806) so a custom board was added.
In Discord it sounded like we didn't want this to be a primary supported board, yet. But opening this PR early so others can see it if they want to pull it in to compile.
