STM8 w/SPL linking problem on blinky

Hi, I’m trying to compile a simple blinky with SPL on my STM8 board (with an stm8s003f3p6 on it). It’s a linking problem, i share my code:

#include "stm8s.h"
#include "stm8s_it.h"
#include "stm8s_gpio.h"

void main()
{
    GPIO_Init(GPIOD, GPIO_PIN_3, GPIO_MODE_OUT_PP_HIGH_FAST);
    while (1)
    {
        GPIO_WriteReverse(GPIOD, GPIO_PIN_3);
        for (volatile uint16_t i = 0; i < 16000; ++i);
    }
}

and this is de output:

*** [.pio/build/stm8sblue/firmware.elf] Error 1

my folder has this files:

blinky
  |-- src
  |    |-- main.c
  |    |-- stm8s_it.c    // from github example
  |-- include
       |-- stm8s_conf.h  // from github example (I commented USE_FULL_ASSERT)
       |-- stm8s_it.h    // from github example

So, the only way I could compile this is by copying the stm8s_gpio.c file from .platformio/packages/framework-ststm8spl/Libraries/STM8S_StdPeriph_Driver/src/ into my project’s “src” folder.

Can I fix this? I’m doing something wrong? Thanks in advance.

PS: I’m using Linux with codium btw.

Per https://github.com/platformio/platform-ststm8/tree/develop/examples/spl-blink/src that file should be in src/ not include/, maybe PIO can then figure out the configuration.

I missed that one, why is that? It compiles now but with 130% of flash memory usage :crazy_face:

The link-time optimizer of sdcc is extremely bad, basically every function / global variable from every compiled file is linked into the final target, even if you use none of the functions. You can see from the compile log that you’re compiling the components CLK, EXTI, FLASH, GPIO, I2C, ITC, IWDG, RST, SPI, TIM,… --> flash overflow.

As this line says

Try commenting out all the unneccsary component in the config file header until the code minimally fits.

Thank you very much, this is rustic compiling then… Is preatty bad, I used SDCC long time ago w/AT89x51, and worked fine because has no HAL, just defines for the SFR, so I never notice the bad optimization.
