Hello, everyone.

AccessPort app was used for test. AccessPort prints ''0x00, 0x55, 0x55, 0x55, 0x55, 0x55, 0x79, 0x3D'' Test code is as follows; int main(void) {     char szTemp[8] = {0x55, 0x55, 0x55, 0x55, 0x55, 0x0D, 0x0A, 0};     uart_init();     led_init();     //Uart_SendString(''hello STM32F205..!!!\r\n\0'');     Uart_SendString(szTemp);     /* Infinite loop */   while (1)   {       Delay_ms(500);         GPIOC->BSRRH |= (1 << 2);         Delay_ms(500);         GPIOC->BSRRL |= (1 << 2);           } }

What is ''AccessPort app''? And what exactly is the problem?

Assume for a second it is not an issue with the code shown, show the code that actually outputs the string.

Use a debugger, confirm that the static data in memory reflects the data you expect to be sent.
