Where do I download micropython for the Xiao esp32c3? version 1.20
the generic esp32c3 does not work. I downloaded and using version 1.19
Is there a way to profile memory? I am running out of RAM by 49 bytes when I load httplib2

I could not get generic esp32c3 micropython to work. That is why I wrote the post.

Hi，
Which step did you go wrong？

#5

For the Xiao ESP32C3 on micropython v1.20 you have to choose GENERIC_C3_USB … not the GENERIC_C3.
But it seem this one is no more available on micropython site for download!
Please send on micropython discussion an issue about that … (I’ve heard they are working for something about firmware image standard)
When I’ve time I will try to make an image about that …

#6

After I flash the micropython 1.20 I get ffffffff returned

#7

I re-test with the new image…
So now it’s ESP32_GENERIC_C3 in micropython web site (download) for the Xiao Esp32c3

The stable version 1.20 work fine (mem free 128752)
The night build (24082023) work fine but so low memory!
