Test projects compiled with GCC doen't work properly #5

Closed WiseLord closed 2 years ago

WiseLord commented 3 years ago

I purchased the board and tried to compile the examples under GCC arm-none-eabi. I converted the following two projects into "Makefile" project type via STM32CubeMX:

Than, I added missing Drivers/BSP/ST7735/*.c files into Makefile, as well as missing defines (TFT96) found in .uvprojx

My results:

So, the question: have the developers ever tried to build their examples in something different than Keil? It would be wonderful to have the examples really OS- and IDE-independent.

1.The compiler overoptimizes 2.just going to step through and see what's wrong with the code 3.This is a bug in our code, need to optimize

WiseLord commented 3 years ago

Actually, I also tried to disable optimization at all, with no effect. When I have some more free time, I'll try to look through it again.

On the other hand, you could also try recent GCC on your side.

OK, If I have time, I will try!

I purchased the board and tried to compile the examples under GCC arm-none-eabi. I converted the following two projects into "Makefile" project type via STM32CubeMX:

  • SDK/HAL/03-LCD_Test/03-LCD_Test.ioc
  • SDK/HAL/08-DCMI2LCD/08-DCMI2LCD.ioc

Than, I added missing Drivers/BSP/ST7735/*.c files into Makefile, as well as missing defines (TFT96) found in .uvprojx

My results:

  • 03LCD_Test compiled with gcc-arm-none-eabi <= 7 works, while one compiled with gcc-arm-none-eabi >= 8 doesn't work. I can see brightness changing (so timer PWM is OK), but display initialization is failed whwn recent GCC is used.
  • 08-DCMI2LCD has the same situation regarding LCD, while camera doesn't work in any case (it's detected, but nothing is shown on the screen even with "good" compiler).

So, the question: have the developers ever tried to build their examples in something different than Keil? It would be wonderful to have the examples really OS- and IDE-independent.

I believe the newest pull request has solved this problem, you can have a try!
