Lopy programmable without expansion board

[StefanoF]

Hi,

Is possible programmable a Lopy or Fipy whitout expansion board,
I've integrated a Lopy on pcb, but not know how do it,
I use a DSD TECH USB a TTL but works only with putty but not works with VScode by Microsoft,

AutoConnect enabled, ignoring 'address' setting (see Global Settings)
Searching for PyCom boards on serial...
No PyCom boards found on USB

somebody kindly can help me?

Many thanks

@StefanoF said in Lopy programmable without expansion board:

You do not need the expansion board of VSCODE to work with a Lopy and to upload firmware or scripts.
For uploading scripts you can use other tools like FileZilla (once WiFi is establised) or rshell (https://github.com/dhylands/rshell.git) or pyboard.py (https://github.com/micropython/micropython/tree/master/tools) or mpr.py with pyboards.py (https://github.com/micropython/micropython/pull/6375) or ampy (retired) or thonny (https://github.com/thonny/thonny) or ....
If you want to upload firmware, you have to set the device into bootloader mode. For that, connect P2 to GND and push reset. Then you can use the pycom updater (CLI or graphics) to upload firmware.

Sorry,

It's possible send file script *.py via UART, or only FTP protocol?

Thanks a lot

@StefanoF All tools I listed below except for FileZilla are sending scripts via UART,
