STM32F0 - The second HAL_SPI_Transmit() call hang the program

[Ciuffoly]

void BSP_SPI_Write(uint8_t ValueL, uint8_t ValueR)
{
 char txData[2];
 char rxData[2];

 txData[0] = 0b10101011;
 txData[1] = (uint8_t *)&ValueL;

 HAL_GPIO_WritePin(GPIOD, GPIO_PIN_2, GPIO_PIN_RESET);
 TIM6delay_us(10);
 HAL_SPI_Transmit(&hspi1, (uint8_t *)&txData, 2, HAL_MAX_DELAY);
 TIM6delay_us(10);
 HAL_GPIO_WritePin(GPIOD, GPIO_PIN_2, GPIO_PIN_SET);

 TIM6delay_ms(100);

 txData[0] = 0b10110011;
 txData[1] = (uint8_t *)&ValueR;

 HAL_GPIO_WritePin(GPIOD, GPIO_PIN_2, GPIO_PIN_RESET);
 TIM6delay_us(10);
 HAL_SPI_Transmit(&hspi1, (uint8_t *)&txData, 2, HAL_MAX_DELAY); // <<< this hang the program
 TIM6delay_us(10);
 HAL_GPIO_WritePin(GPIOD, GPIO_PIN_2, GPIO_PIN_SET);
}
