Clocks Initialization wrong (SOLVED).

Hi all!,

I'm, triyng to program using CMSIS in order to learn how registers works.

If I use the SystemClock_Config() generated by STM32CubeIDE all works properly, but if I use my own rutine, the TFT wired to SPI3 dont show the fonts properly (I think it must be something about activate/set some missing clock)

This is the SystemClock_Config():

void SystemClock_Config(void)
{
 RCC_OscInitTypeDef RCC_OscInitStruct = {0};
 RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
 RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
 
 /** Initializes the RCC Oscillators according to the specified parameters
 * in the RCC_OscInitTypeDef structure.
 */
 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE;
 RCC_OscInitStruct.HSEState = RCC_HSE_ON;
 RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1;
 RCC_OscInitStruct.HSIState = RCC_HSI_ON;
 RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
 RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
 RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
 RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL4;
 if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
 {
 Error_Handler();
 }
 /** Initializes the CPU, AHB and APB buses clocks
 */
 RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
 |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
 RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
 RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
 RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
 RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
 
 if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
 {
 Error_Handler();
 }
 PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_USART1|RCC_PERIPHCLK_I2C1;
 PeriphClkInit.Usart1ClockSelection = RCC_USART1CLKSOURCE_SYSCLK;
 PeriphClkInit.I2c1ClockSelection = RCC_I2C1CLKSOURCE_HSI;
 if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK)
 {
 Error_Handler();
 }
}

And this is my own rutine to set all clocks. Can you see what I'm doing wrong?

void MyClockInit(void)
{
	/*
	 * Use a crystal 8/16MHz on HSE, to work at 64MHz.
	 */
 
	//Start HSI
	RCC->CR |= RCC_CR_HSION;
	while(!(RCC->CR & RCC_CR_HSIRDY));
 
	//SystemClock =l HSI, in order to stop PLL and change it.
	RCC->CFGR &= ~RCC_CFGR_SW;
	while(RCC->CFGR & RCC_CFGR_SWS );
 
	//Stop PLL and wait.
	RCC->CR &= ~RCC_CR_PLLON;
	while(RCC->CR & RCC_CR_PLLRDY);
 
	//PLL = HSE/PreDiv
	RCC->CFGR |= RCC_CFGR_PLLSRC_HSE_PREDIV;
 
	//HSE Input to PLL divided by 1
	RCC->CFGR2 &= ~RCC_CFGR2_PREDIV;
	RCC->CFGR2 |= RCC_CFGR2_PREDIV_DIV1;
 
	//PLL x8 = 64MHz for 8MHz crystal
	//PLL x4 = 64MHz for 16MHz crystal
	RCC->CFGR &= ~RCC_CFGR_PLLMUL;
	RCC->CFGR |= RCC_CFGR_PLLMUL4;
 
	//Frec. AHB = 64MHz
	RCC->CFGR &= ~RCC_CFGR_HPRE;
 
	//Frec. APB1 = 32MHz
	RCC->CFGR &= ~RCC_CFGR_PPRE1;
	RCC->CFGR |= RCC_CFGR_PPRE1_DIV2;

	RCC->CFGR &= ~RCC_CFGR_PPRE2;
	RCC->CFGR &= ~RCC_CFGR_PPRE2_DIV1;
 
	//Start HSE and wait for HSE_RDY
	RCC->CR |= RCC_CR_HSEON;
	while(!(RCC->CR & RCC_CR_HSERDY));
 
	//Start PLL and wait for PLL_RDY
	RCC->CR |= RCC_CR_PLLON;
	while(!(RCC->CR & RCC_CR_PLLRDY));
 
	//adjust LATENCY = 2 for 64MHz
	FLASH->ACR &= ~FLASH_ACR_LATENCY;
	FLASH->ACR |= FLASH_ACR_LATENCY_1;
 
	//SystemClock = PLL
	RCC->CFGR &= ~RCC_CFGR_SW;
	RCC->CFGR |= RCC_CFGR_SW_PLL;
	while((RCC->CFGR & RCC_CFGR_SWS_0) && !(RCC->CFGR & RCC_CFGR_SWS_1));
 
	//USART1 = SystemClock
	RCC->CFGR3 |= RCC_CFGR3_USART1SW_0 | RCC_CFGR3_I2C1SW ;
 
	RCC->APB2ENR |= RCC_APB2ENR_SYSCFGEN | RCC_APB2ENR_USART1EN ; //hABILITA EL SYSTEM CLOCK.
	RCC->APB1ENR |= RCC_APB1ENR_SPI3EN | RCC_APB1ENR_I2C1EN| RCC_APB1ENR_TIM2EN| RCC_APB1ENR_TIM4EN;
	//Set GPIOA to GPIOF
	RCC->AHBENR |= RCC_AHBENR_ADC12EN | RCC_AHBENR_ADC34EN | RCC_AHBENR_GPIOAEN | RCC_AHBENR_GPIOBEN | RCC_AHBENR_GPIOCEN | RCC_AHBENR_GPIOFEN;
 
	SystemCoreClockUpdate();
	//Set the SystemCoreClock variable.
}

Thanks in advance!
