FPGA2HPS SDRAM Bridge Appears to Be Working but data is Zeros

SOLVED !!!!!

I switched my allocation of the memory buffers to:

static char * dmakbuf1; "kbuf"

static char * dmakbuf2;

static dma_addr_t handle;

static dma_addr_t handle2;

static size_t size = (1024 * PAGE_SIZE);

dmakbuf1 = dma_alloc_coherent(NULL, size, &handle, GFP_KERNEL);

if ( dmakbuf1 == NULL ) printk( KERN_ALERT "dma_alloc_coherent FAILED !!!! BUF1 \n" );

dmakbuf2 = dma_alloc_coherent(NULL, size, &handle2, GFP_KERNEL);

if ( dmakbuf2 == NULL ) printk( KERN_ALERT "dma_alloc_coherent FAILED !!!! BUF2 \n" );

THE RETURN VALUES == "handle" the physical address is what I give to the FIRMWARE

and the "dmakbuf" is what the user space code needs (NO ioremap)

Hope this helps someone else.
