I have just updated to Cube v4.0 which I also think updated the firmware package for the chip I am using (STM32F030RCTx). There is a bug in the initialisation code for the DMA that causes the project not to be compiled at all.
Pre-update:
__HAL_DMA1_REMAP(HAL_DMA1_CH3_SPI1_TX);
Post-update:
if (__HAL_DMA1_REMAP(HAL_DMA1_CH3_SPI1_TX) != HAL_OK)
{
Error_Handler();
}
The macro
__HAL_DMA1_REMAP
is defined as:
#define __HAL_DMA1_REMAP(__REQUEST__) \
do { assert_param(IS_HAL_DMA1_REMAP(__REQUEST__)); \
DMA1->CSELR &= ~((uint32_t)0x0F << (uint32_t)(((__REQUEST__) >> 28) * 4)); \
DMA1->CSELR |= (uint32_t)((__REQUEST__) & 0x0FFFFFFF); \
}while(0)
It's easy to see why this will not work in an if statement. I am having to edit the code manually every time I generate the code.
