Arduino for STM32

Posted: **Sun Oct 10, 2021 2:05 pm**

Hi
I have been using the STM32F103C8 on the Arduino IDE for some time with the following setup:

#define       HC12      Serial1               // TX-PA9/RX-PA10
#define       MATRIXSER Serial2                // TX-PA2/(RX-PA3 - NOT IN USE)
#define       BAUD      9600

and all worked fine until this week. Without any changes from me (that I'm aware of) I now get a compile failure:
collect2.exe: fatal error: cannot find 'ld'
compilation terminated.
exit status 1
Error compiling for board Generic STM32F103C series.

If I remove the reference to Serial2 I can compile without issue - so it seems that Serial2 has changed somehow...

Attempting to understand why, I have updated A_IDE to 1.8.16, uninstalled deprecated Core files and changed my Additional Board Manager URLs to the latest I can find:
https://github.com/stm32duino/BoardMana ... index.json, http://dan.drown.org/stm32duino/package ... index.json

I am stumped; can anyone shed any light on, and proffer a solution to this issue?

Indicates that you used Rogers's core.
Dan drown package is not official. Try the repo as described in the wiki of Rogers's core.

Ok.
I added one line before the defines

Code: Select all

HardwareSerial Serial2 (PA2, PA3);

which was not needed before last week - and hey, presto!

Thank you for your input.
