Is STM32F7508-DK board supported?

It looks like that STM32F7508-DK board is supported (STM32F7508-DK — PlatformIO latest documentation). I customized cmis-blink example (given here http://github.com/platformio/platform/raw/master/examples/cmsis-blink/platformio.ini) and ran pio run but ran into the following:

My platformio.ini is following

[env:disco_f750n8]
platform = ststm32
board = disco_f750n8
framework = cmsis

Any pointers?

The link is dead.

I think you mean platform-ststm32/examples/cmsis-blink at develop · platformio/platform-ststm32 · GitHub.

If you are using the code from

You can see that it has these custom #ifdef STM32F7 etc blocks. These get activated by defining that macro in the environment for the specific microcontroller.

E.g.

So either use a platformio.ini like

[env:disco_f750n8]
platform = ststm32
board = disco_f750n8
framework = cmsis
build_flags = -DSTM32F7

And the thing will compile.

Or, just delete all condition ifdef blocks except the STM32F7 and then make it unconditional, aka just the main.c as

#include "stm32f7xx.h"
#define LEDPORT (GPIOB)
#define LED1 (0)
#define ENABLE_GPIO_CLOCK (RCC->AHB1ENR |= RCC_AHB1ENR_GPIOBEN)
#define _MODER    MODER
#define GPIOMODER (GPIO_MODER_MODER0_0)

void ms_delay(int ms)
{
   while (ms-- > 0) {
      volatile int x=500;
      while (x-- > 0)
         __asm("nop");
   }
}

//Alternates blue and green LEDs quickly
int main(void)
{
    ENABLE_GPIO_CLOCK;              // enable the clock to GPIO
    LEDPORT->_MODER |= GPIOMODER;   // set pins to be general purpose output
    for (;;) {
    ms_delay(500);
    LEDPORT->ODR ^= (1<<LED1);  // toggle diodes
    }

    return 0;
}

Thanks. I should have looked under the hood a bit. Setting build flags did the trick.
