AWR1243BOOST: Interfacing TM4C1294 and AWR1243 with SPI read & write function

Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243
Hi,
To establish SPI communication between TM4C1294 & AWR1243, we have tried porting the code from mmwavelink
libraries, but for the function rlsSpiRead() we have the below part of the code in mmwl_ftdi_port.c,
which is dependent on OS[API functions],but we are porting the code without API functions.
Can you suggest how to use this function without using OS and to establish communication using SPI with
TM4C1294 and AWR1243?
[status = FT_Read(pDevCtx->spiHandle, (preadbuffer + i),
(DWORD)spiWordSize, (LPDWORD)&tempByteRecv);
tempData = *(preadbuffer + i);
*(preadbuffer + i) = *(preadbuffer + i + 1);
*(preadbuffer + i + 1) = tempData;]
Regards,
Nitesh
