Hi Jatin

I find the focus of Flash was changed... When programm run normally, Then make the crystal stop to self_oscillate(Such as: finger touch crystal pin) a moment...poweroff...poweron...The flash was changed, programm did not go on. I used some code at beginning of main() as follow: //----------- int main(void) { _asm(''sim\n''); // Disable interrupt FLASH_PUKR = 0x00; // LOCK flash RST_SR = 0x1F; // Clear reset flag CLK_CKDIVR = 0x00; // HSI_DIV = 1; HSE_DIV = 1 CLK_ECKR = 0x01; // HSE clock on CLK_SWCR = 0x06; // Enable switch and interrupt CLK_SWR = 0xB4; // HSE as the master clock. _asm(''rim\n''); // Enable interrupt while(!gFlag_run); ...... return 0; } //------------ volatile unsigned char gFlag_run = 0; @near @interrupt void CLK_IRQHandler(void) { CLK_SWCR &= ~0x08; // clear SWIF gFlag_run = 1; // Set run flag return; } //------------ But the Devil is still live.

Hello

Faint! The evil was killed...When I kick out 'static @inline' key of all fuctions declare. That wiil be appreciated from the mail of Joyce Yan Mentioned it! Thanks for help of all ST Engineers, STM8A is good 8bit MCU, But I am not sure Whether STVD(Comsic) need be improved ...The dangerous of flash changed has be resolved Completely?

Glad to know that the problem is solved at your end.

But we would like to investigate it in detail. Joyce will contact you for this. Thanks Regards, Jatin
