Hi all, 

I have a very interesting problem that I havent been able to solve for days. I have two different computers and they are setup to be the same.

On one computer, the RX FIFO buffer (RX_FIFO_RD) can be corrected referenced to /mtb_shared/mtb-pdl-cat1/release-v3.7.0//devices/COMPONENT_CAT1A/include/ip/cyip_scb.h. It builds compiles and runs.

On the second computer, the same RX_FIFO_RD cannot be resolved, and asks me to select which header to use cyip_ble.h, cyip_i2c.h and cy_scb.h from COMPONENT_CAT1A, COMPONENT_CAT1B or COMPONENT_CAT1C. It seems that it just cant make the link to the correct header after using 'Device Configurator'.

I cannot for the life of me find out why this isn't working properly on the second computer. Thanks for your help

Code snippet is below:

void configure_rx_dma(uint32_t* buffer_a, uint32_t* buffer_b, cy_stc_sysint_t* int_config)
{

cy_en_dma_status_t dma_init_status;
const cy_stc_sysint_t intRxDma_cfg =
{
.intrsrc=sRx0_IRQ,
.intrPriority = 7u
};
// -------------------------------------------------------------------------------------------------
// SCB0 Slave 0
// -------------------------------------------------------------------------------------------------
/* Initialize SCB0 descriptor 1 */
dma_init_status = Cy_DMA_Descriptor_Init(&sRx0_Descriptor_0, &sRx0_Descriptor_0_config);
if (dma_init_status!=CY_DMA_SUCCESS)
{
handle_error();
}

/* Initialize SCB0 descriptor 2 */
dma_init_status = Cy_DMA_Descriptor_Init(&sRx0_Descriptor_1, &sRx0_Descriptor_1_config);
if (dma_init_status!=CY_DMA_SUCCESS)
{
handle_error();
}

// Initialise DMA channel 20 (corresponds to SCB2 rx)
dma_init_status = Cy_DMA_Channel_Init(sRx0_HW, sRx0_CHANNEL, &sRx0_channelConfig);
if (dma_init_status!=CY_DMA_SUCCESS)
{
handle_error();
}

/* Set for (SCB0) source and destination address for descriptor 1 */
Cy_DMA_Descriptor_SetSrcAddress(&sRx0_Descriptor_0, (uint32_t *) &sSPI0_HW->RX_FIFO_RD);
Cy_DMA_Descriptor_SetDstAddress(&sRx0_Descriptor_0, (uint32_t *) buffer_a);

/* Set for (SCB0) source and destination address for descriptor 2 */
Cy_DMA_Descriptor_SetSrcAddress(&sRx0_Descriptor_1, (uint32_t *) &sSPI0_HW->RX_FIFO_RD);
Cy_DMA_Descriptor_SetDstAddress(&sRx0_Descriptor_1, (uint32_t *) buffer_b);

// All the lines above sets stuff for the descriptor structure
// The follow line sets the current(starting) DMA descriptor state, so will start with descriptor 0
Cy_DMA_Channel_SetDescriptor(sRx0_HW, sRx0_CHANNEL, &sRx0_Descriptor_0);

/* Initialize and enable interrupt from RxDma */
Cy_SysInt_Init(int_config, &rx_dma_complete); // system interrupt for CPU
NVIC_EnableIRQ(int_config->intrSrc);

/* Enable DMA interrupt source. */
Cy_DMA_Channel_SetInterruptMask(sRx0_HW, sRx0_CHANNEL, CY_DMA_INTR_MASK);

/* Enable channel and DMA block to start descriptor execution process */
Cy_DMA_Channel_Enable(sRx0_HW, sRx0_CHANNEL);
Cy_DMA_Enable(sRx0_HW);
