Unable to compile blink project when board Maple(RET6) is selected from Arduino studio

[yuanb]

Hi,

I hope this is the right place to log this issue, if not please close this issue and tell me where to log it

Environment:
OS: Mac OS X
Arduino Studio 1.18.12
STM32duino: 2020.6.20
Board: Leaflabs Maple RET6
Additional Board Manager URLs: http://dan.drown.org/stm32duino/package_STM32duino_index.json

Please check attached image for details. The same code compiles fine when Maple Rev3 is selected.
My remedy is to add the following to the beginning of Arduino15/packages/stm32duino/hardware/STM32F1/2020.6.20/cores/maple/sdio.cpp. Sample blink project, rtos blink project compiled and runs fine with this change.

Note, if I uncomment the #ifdef __cplusplus block, the code wont compile, same error.

//#ifdef __cplusplus
// #include
// using namespace std;
//#else // C
#include <stdlib.h>
#ifndef min
#define min(a,b) ((a)<(b)?(a):(b))
#endif // min

#ifndef max
	#define max(a,b) ((a)>(b)?(a):(b))
#endif // max

//#endif // __cplusplus

OK, I will have a look on this.

Your core files are from: http://dan.drown.org/stm32duino/package_STM32duino_index.json
This error is related to the Roger's core: https://github.com/rogerclarkmelbourne/Arduino_STM32
I think this is fixed by this commit: rogerclarkmelbourne@58ca12a
Please check out the new file sdio.cpp and try to compile again.

@stevstrong I don't understand how Arduino studio manage its packages. Are you saying I'm actually not using your code?

[stevstrong]

Yes, that is what I am saying.
If you want to use my core files, then you have to install it manually, identically as described here: https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Installation
just that the package you have to download is this one: https://github.com/stevstrong/Arduino_STM32/archive/master.zip

[yuanb]

I have tried both. Roger's core downloaded from this link, worked.
https://github.com/rogerclarkmelbourne/Arduino_STM32/archive/master.zip

Your master core failed with some errors

[stevstrong]

It is good that it works with Roger's core, use that, you don't need to use my core, I do not support all board types.
Can you please post the error messages as text?

[stevstrong]

I will close this as it seems to be resolved.
