There was a bug in the the UART init function.

The latest release seems to have solved it.

UART0 Output: Looping on boot, but only when I take out the USB lines or change the sdkconfig.board file. Hard to say if I am doing something wrong, or if I am fighting a bug.

I have created a custom board with ESP32-S2-WROVER-I. Using an external serial adaptor for programming. I am new to ESP32 and Micropython, but a mid-skill-level programmer for many other microcontrollers. The GENERIC-S2 port compiled just fine, but it appears to be setup for USB REPL. I can see the ...

Success! I am not sure where the previous effort went wrong, but starting from scratch (all new VM) everything seems to work just fine. https://docs.espressif.com/projects/esp-idf/en/v4.4/esp32s2/get-started/index.html#get-started-get-esp-idf These instructions work just fine. If you have trouble - ...

Thank you so much for the notes. I believe I went through those steps - but it is entirely possible I messed something up along the way. I am going to make a clean start and see if I can stop and take notes of anything that seems to be an indication of a problem. At this point, I have been trying to...

I have spent a few days trying to setup to compile micropython for a custom board that I made. Running a dedicated Ubuntu VM, I installed ESP-IDF and cloned micropython. As best I know how, I followed the smattering of README's, instructions, and forum posts trying to get anything to compile. It see...

It sounds like you may need to disable the USB and recompile?

I am having the same issue as the OP and still looking for a solution.

Thank you, makes sense. As a side note, I now know how to compile micropython from source even if it is not needed. :-) As for upip, is that intended to be used from the desktop command line - or just a device running micropython with a network connection? I am using VS Code and trying to figure out...

UPDATE: I learned a few things in the past few hours....uAsyncio is a built-in module and I was running an older version of uPython. I updated the firmware to a newer generic ESP32 build and installed that with esptool utility. To check the version of uasyncio: >>> import uasyncio as asyncio asyncio...

I am trying to figure out how to install uasyncio V3 and other modules in general. So far, I have tried upip - but that seems so have installed the older version (not even sure how to verify version) I am curious how to manually download and install it (without upip or a network connection). At the ...
