error message in compiling STM32F030C8T6> RBOARD_32F030C8T6 >variant.h error

[GitHubedklam]

hello; I am new to using STM32F030C8T6 with arduino IDE. I followed r-pv instruction (r-pv/rSTM32F030C8T6_ProMiniPlus) . When I compile a sample sketch "blink" I received the following error >
" Warning: Board STM32:stm32:Nu030F4cleo_64 doesn't define a 'build.board' preference. Auto-set to: STM32_NU030F4CLEO_64
c:/users/edward/appdata/local/arduino15/packages/stm32/tools/xpack-arm-none-eabi-gcc/9.2.1-1.1/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: cannot open linker script file C:\Users\Edward\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.9.0\variants\RBOARD_F030C8T6/ldscript.ld: Invalid argument
collect2.exe: error: ld returned 1 exit status

Error compiling for board Generic STM32F0 series. "

Please help me to resolve this.Thank in advance.

Hi, do you select the board RBOARD_F030C8T6 on the arduino IDE? selecting "generic stm32f0 series" on the "board" menu, then pick "RBOARD_F030C8T6" on the "board part number" menu.

The error sounds like the board it's not selected and/or the editing of the board.txt file failed.

I checked and I am sending you clip shots so you can double check to see what I missed. The arduino ide under "generic stm32f0 series" on the "board" menu > no RBOARD_F030C8T6 . instead it has STM32F030C8T6 STProMiniPlus so I choose this as it matches the board. During compile the first warning almost immediately " Warning: Board STM32:stm32:Nu030F4cleo_64 doesn't define a 'build.board' preference. Auto-set to: STM32_NU030F4CLEO_64" it this normal ? finally failure with warning as noted earlier.

Hi, yes, the last screen shows a boards.txt really mess up, it shows like lines were added at the end of other lines instead of just add the code at the end of one block of text.

Your boards.txt looks like:

line0line4
line1line5
line2line6
line3line7

line8
line9
...

and, per instructions, should look like:

line0
line1
line2
line3

line4
line5
line6
line7

line8
line9
...

so the idea it's that you'll find this text:

and just add the text on the instructions to leave it as:

Did you make a copy of the boards.txt to start again? if not I'm afraid that you'll have to reinstall arduino to start again.

I did have make a backup. I made the change as per your instruction. I selected "STM32F030C8T6 STProMiniPlus" in "Board part number".
I compiled and upload. It uploaded ok and my test program " Blink" works. :)
Many thanks for your help and saved me many frustration. I was about to trash this (bought by mistake) and buy the STM32F103C which I wanted at the first place.

Glad that you make it work.
I like this MCU, when I got them was like 5pieces x$3usd, the bare IC of course, isn't as powerfull as the F103C but it's cheap and still it's way super-charged than, lets say, an atmega328p.

BTW, the ST Core v2.0 it seems that will have support for this MCU, so it won't be needed any modification.

thanks for the insight

Thanks for sharing and provide details. Your post is the only one I could find ( after searching for hours ! )on how to use this board F030C with Arduino IDE.
