Arduino for STM32

Which core?
Which board?
Maybe the board has already reserved these pins for other purpose.

Maybe you have to install libusb-1.0?
I do not have experience with linux at all.

Please set "verbose" on in Arduino settings for compilation, then try again and post here the message.

You use Arduino_STM32 or STM32duino?
Please post the complete flashing process output.

The error message is clear: you have to cast the second parameters of the function calls to

Code: Select all

byte error = eep.write( 0, (byte*)test, sizeof(test));

and

Code: Select all

eep.read( 0, (byte*)bufer, sizeof(test));

In addition, you have to change the size of buffer to:

Code: Select all

char buffer[sizeof(test)+1];

Try this one:

This is set to use SPI1 and chip select pin PA4.

Well, then what about this sentence:

I think you should post an issue on the github page of khoih.

A DTR pulse is not enough, a magic sequence should be also transmitted over USB serial.
You can try to manually reset the board short before you upload the code.
