Description

Clean tinypico with esptool.exe --chip esp32 --port COM9 erase_flash

then flash circuitpython via esptool.exe --chip esp32 --port COM9 write_flash -z 0x1000 ..\adafruit-circuitpython-unexpectedmaker_tinypico-en_US-8.0.0-beta.6.bin

No drive shows up and connecting via putty outputs the error messages

Additional information

This is on the original run of tinypicos so the v1 which is confirmed by the esptool when flashing. I am able to install and run micropython.

My understanding is that esptool.exe is obsolete. We use esptool.py. I am not sure what esptool.exes command line args are but, we flash CircuitPython starting at 0x0000, not 0x1000. Could you try that?

[luigi311]

looking at the output for esptool.exe it is just a wrapper for the python script for windows

.\esptool.exe --chip esp32 --port COM9 write_flash -z 0x1000 ..\tinypico-20220618-v1.19.1.bin esptool.py v4.4

Just in case though i did install esptool from pip and ran that with the 0x0000 and that seems to be working so it might of just been the 0x1000 vs 0x0000 difference.

I am able to connect via putty serial and hello world completes but i do not see the circuitpy drive, according to the cricuitpython getting started that should appear once connected

The TinyPico is a plain ESP32, which does not have native USB, so it cannot present a CIRCUITPY drive. You'll have to use Thonny or similar to load files onto it. The REPL is via the USB-serial converter cip.

I see, thanks for all the info. Ill go ahead and look into what i can use for this and use Thonny to start my search. Looks like you solved all my issues so i can go ahead and close the ticket, thanks for the speedy help

Glad things are working. Check out https://learn.adafruit.com/circuitpython-with-esp32-quick-start for help with such boards. It does not mention Thonny (but maybe it should). It talks about using the web workflow which is new and a bit experimental.
