"Cache New" Nut My_system_stm32h7.c file for Clock config: 4 Lines too much

[flyer31]

Sorry, I just recognized that in the file I appened to the "Cache New" Nut question, I kept 4 test lines to get this "Code 32 alignment" done before the for wait loop ... .

But this does not work ... this will unfortunately be refused by the compiler.

So please change this in line 192..200:

Wrong state:

//  __asm("ALIGN 32\n");
  iDelay= 0;
  __asm {
    AND iDelay, iDelay, #0
    ALIGN 32
    
  }
  while( !(PWR->D3CR & PWR_D3CR_VOSRDY))
  { if( iDelay++ > IFLOOPEND_1ms) return 0; } 

Correct it should look like this:

  iDelay= 0;
  while( !(PWR->D3CR & PWR_D3CR_VOSRDY))
  { if( iDelay++ > IFLOOPEND_1ms) return 0; }

Hello @flyer31​ ,

Could you please precise where exactly is this code? which compiler are you using?

Thanks,

It was Keil, using functionality not supported by the in-line compiler, and require changes in the segment alignment settings in a .s file. These questions were cross-posted here http://www.keil.com/forum/64067/arm-code-alignment-for-stm32h7-flash-access-loops/
