How to program ESP32?

Checking out Flowcode V9, very excited to see ESP32 support.
Playing around with it now, I do understand that it's new and documentation hasn't caught up yet.
Got some ESP32 stuff running in sim but how do I compile to chip?
Thanks...

Hi chico,
Take a look at
this link.
You will see a pdf file that contains step by step instructions.

Thanks. I viewed the link you sent, I'd already loaded the toolchain.
I can get my test file to compile, but programming fails:
Code: Select all
Done! You can now compile ESP-IDF projects.
Go to the project directory and run:
idf.py build
Usage: idf.py [OPTIONS] COMMAND1 [ARGS]... [COMMAND2 [ARGS]...]...
Try 'idf.py --help' for help.
Error: Invalid value for '-b' / '--baud': flash is not a valid integer
Programming Failed
C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\ESP\Batch\esp32_prog.bat reported error code 0x1
Autoclose turned off
FINISHED
The listed com port in project options is: COM3 (Silicon Labs CP210x USB).
Any ideas?

Have you selected the correct port in the project options screen?
I have found it best to have tge board connected before running Flowcode.

Yes, the correct programmer port is listed in Project Options: COM3 (Silicon Labs CP210x USB).
I'm using a HiLetGo ESP32S (Works as Node32s in Arduino IDE). I've tried the various ESP options in Flowcode (ESP32S, ESP32_WROOM_32, ESP32_WROVER), all compile but get the same programmer error when trying to upload:
Code: Select all
Error: Invalid value for '-b' / '--baud': flash is not a valid integer
Programming Failed
C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\ESP\Batch\esp32_prog.bat reported error code 0x1
No problem uploading to the same board with the Arduino IDE when Flowcode isn't open.

There is a bug relating to setting the com port.
Please read this post, carefully
